Doxepin – USA


On June 24, 2020, District Court of Delaware largely accepted Magistrate Judge’s recommendation & granted Defendants motion for damages because of breach of Settlement and License Agreement.

Background:

Somaxon and ProCom (Plaintiffs) filed Hatch-Waxman suit against Mylan as well as three other generic pharmaceutical companies (Actavis, Par & Zydus) for filing ANDA against Silenor® (Doxepin) tablets. Plaintiffs and Mylan entered into the Agreement on July 17, 2012 & as a result it granted license to Mylan to sell Authorised Generic (AG) starting from Jan. 01, 2020 for 180 days.  But in Oct.2019, Currax informed Mylan that Currax planned to launch its own AG product “on or around Jan. 1, 2020.” Mylan filed this motion to enforce the Agreement on Dec. 23, 2019. The Court said that it must determine whether Currax’s plan to market and sell its own AG constitutes a breach of the parties’ Agreement, if § 5.1(a) of the Agreement is enforceable, and if Defendants are entitled to specific performance.

Court’s analysis:

Court said that there is no dispute that there is contract & Plaintiffs breached an obligation in the Agreement. The parties only dispute is whether the breach was material. The law gives rise to a remedy for both non-material breach and material breach of contract; it is not necessary for the Court to determine if Plaintiffs’ breach was material to enforce the Agreement. Thus, Plaintiffs has breached the agreement. With respect to its enforcement, Plaintiffs argued that § 5.1(a) is illegal under current antitrust law (F.T.C. v. Actavis, Inc.. 570 U.S. 136 (2013)), which would make it unenforceable. The Court said that the plaintiffs must prove “payment for delay” to prove anticompetitive effects in the context of reverse settlement agreements. At this stage of the proceedings, it is not sufficient to allege a harm; Plaintiffs must offer evidence that there is one. Plaintiffs submitted two declarations in connection with their opposition to the motion but neither one offers any evidence of any anticompetitive harm. Moreover, “no-AG” provision in the agreement may be subject to the rule-of-reason analysis “when it represents an unexplained large transfer of value from the patent holder to the alleged infringer.” Here, Plaintiffs have not shown that § 5.1(a) of the Agreement fulfills this criterion. Second, even if the Court determines a given “no-AG” provision is subject to rule-of-reason analysis, the ultimate outcome of that analysis turns on myriad facts. (describing the fact-intensive inquiry required for rule-of-reason analysis). The Plaintiffs have not presented any facts that indicate there were anticompetitive effects in this case. The Court thus found that the Plaintiffs have failed to meet their burden to show anticompetitive effects.

With respect to damages Court said that Defendants have sufficiently proven damages. By virtue of this breach Plaintiffs have conceded that Defendants incurred damages in the form of a decreased market share. Defendants now have to compete with Plaintiffs’ AG and Actavis’ AB-rated generic rather than with just the Actavis generic. Defendants here asked for specific performance of § 5.1(a) of the Agreement. Court said that “Specific performance is an extraordinary remedy” that is appropriate when “assessing money damages would be impracticable or would fail to do complete justice.” Defendants asserted that the harms that flows from the breach are: “lost revenues, loss of market share, price erosion, and loss of customer goodwill” as well as the loss of the first mover advantage. The Magistrate Judge recommended that an order of specific performance is an appropriate remedy in this matter. But Court said that while that recommendation made sense at the time the Magistrate Judge made it, the passage of time leads court to conclude that the balance of the equities does not now weigh in favor of granting specific performance. Defendants have already lost the majority of their semi-exclusive window for selling the AG of Silenor®. (Defendants were granted 180 days of semi-exclusivity for their AG starting on January 1, 2020. It is now late-June of 2020) By the time Plaintiffs are able to pull their AG from the market the Defendants’ exclusivity period will likely have lapsed. An order of specific performance is not appropriate when monetary damages would be sufficient to compensate the injured party, and when it is possible to arrive at a legal measure with a reasonable degree of certainty. The Court thus found the more appropriate remedy is monetary damages. Defendants are free to pursue damages for their breach of contract claim.

Weekly Patent Litigation Round-Up


Kymab Wins Supreme Court Case Against Regeneron

Cambridge, UK; 24 June, 2020: Kymab, a clinical-stage biopharmaceutical company developing fully human monoclonal antibody therapeutics, is pleased to announce that the Supreme Court of the United Kingdom has held that all of the claims of two patents (European Patents EP(UK) 1 360 287 and EP(UK) 2 264 163, the ‘Murphy patents’) owned by Regeneron Pharmaceuticals Inc that were asserted against Kymab are invalid. The Court’s decision upholds the February 2016 decision of the High Court trial judge, Mr. Justice Henry Carr to revoke the claims and reverses the Appeal Court’s determination that they were valid. It was held that the relevant claims of the Murphy patents were invalid for insufficiency because they did not enable the ordinary skilled person to work the claimed invention across the breadth of the claims, in line with established jurisprudence of the UK courts and European Patent Office…


Mylan, seeking to market Victoza generic, convinces panel to start up patent review

Mylan, coming off a big patent win against Biogen, aims to launch a copycat version of Novo Nordisk's diabetes drug Victoza. Now, a U.S. patent office panel says there's a "reasonable likelihood" that Mylan could successfully nix a Victoza patent that covers the blockbuster med through early 2026. The U.S. Patent Trial and Appeal Board instituted an inter partes review on patent No. 8,114,833, which covers Victoza's formulation and methods for producing it effectively. Mylan claims the patent is invalid because it covers an obvious invention. After hearing initial arguments over the patent, the board found a “reasonable likelihood” Mylan would win the case. The review process is set to play out through late 2020 and early 2021, according to a scheduling order...


IPAB stays revocation of Pharmacyclics’ patent on anti-cancer drug Ibrutinib

The Intellectual Property Appellate Board (IPAB) has granted an interim stay on an order issued by the Indian Patent Office removing a patent of Pharmacyclics for anti-cancer drug Ibrutinib. Ibrutinib sold by Pharmacyclics Inc, a Silicon Valley-based biopharmaceutical company and part of AbbVie under the brand name ‘Imbruvica’ is used to treat adults with mantle cell lymphoma (MCL), chronic lymphocytic leukaemia (CLL)/small lymphocytic lymphoma (SLL), Waldenström’s macroglobulinemia (WM), marginal zone lymphoma (MZL), and chronic graft versus host disease (cGVHD). NR Meena, Joint Controller of Patents and Designs, in an order issued on March 4, 2020 revoked the patent based on a post-grant opposition filed by Laurus Labs. The patent office observed the claims made by Pharmacyclics are obvious to an ordinary person skilled in the art and that the drug lacks any inventive step that would make it superior to other existing formulations…


Neurim v. Mylan: UK Court of Appeal denies interim injunction in face of a launch-at-risk, but are damages really adequate?

As this Kat was strolling home Wednesday afternoon, he received a call from his old pal Joost Duijm. On the ball as always, Joost told me that the appeal in Neurim Pharmaceuticals v. Mylan had been handed down [first instance decision here, appeal decision here]. The Court of Appeal has upheld the decision by Marcus Smith J. to deny an interim injunction against a generic company that launched at risk. Big news indeed. The UK patent courts are known across Europe, among many other things, for having developed a clear-the-way doctrine: if a generic entrant does not institute invalidity proceedings against the patent well in advance of a product launch, that is a strong argument in favour of granting an interim injunction awaiting trial and the status quo is maintained…


Bayer inks largest settlement in pharma history with $10B Roundup deal

Bayer volunteered for quite a headache with its 2018 pickup of Monsanto and weedkiller Roundup, what with lawsuits piling up and investors chomping at the bit. Now, it's looking to relieve the pain of that multibillion-dollar legal overhang with an enormous deal to escape the Roundup litigation. Bayer will dole out between $10.1 billion and $10.9 billion—the single largest settlement in pharma history—to put an end to thousands of lawsuits tied to its acquisition of Monsanto and glyphosate-based Roundup. As part of its agreement, Bayer will pay between $8.8 billion and $9.1 billion to settle roughly 125,000 Roundup lawsuits combined in a California multi-district litigation and multiple state bellwether trials, Bayer said. The deal will settle roughly 75% of all Roundup suits and includes an allowance to pay out claims that have not been resolved…

Mifepristone - USA


Claim Construction (District of New Jersey): Jun. 23, 2020
Civil Action No.: 18-3632
Plaintiff: Corcept Therapeutics, Inc.
Defendants: Teva Pharmaceuticals USA, Inc.

Before the Court are the briefs and supporting materials of Plaintiff and Defendant regarding their request for patent claim construction pursuant to Local Patent Rule 4.5(a). The Court held a Markman hearing on March 5, 2020 regarding patent claims in Plaintiff’s U.S. Patent Nos. 8,921,348 (“the ʼ348 Patent”) and 9,829,495 (“the ’495 Patent”). After carefully considering the parties’ written and oral arguments, this Court construes the three disputed claim terms as discussed below.

Claim construction:

(1) “achieve mifepristone blood levels greater than 1300 ng/mL,” (claim 1 of the ’348 Patent)

Plaintiff’s: “ensure mifepristone blood levels remain greater than 1300 ng/mL”
Defendants: Plain and ordinary meaning; no construction required. Alternatively, plain and ordinary meaning, which is: “ensure that the patient’s mifepristone blood levels are greater than 1300 ng/mL”
The Court: Plain and ordinary meaning; no construction required.

(2) “a method of concurrently treating Cushing’s syndrome and differentially diagnosing adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome,” (claim 1 of the ’495 Patent)

Plaintiff’s: “a method of concurrently treating Cushing syndrome and [differentially diagnosing adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome / obtaining a measurement indicative of differential diagnosis of adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome] in order to recommend transphenoidal surgery or appropriate imaging to identify source of the ectopic ACTH secretion”
Defendants: Plain and ordinary meaning; no construction required. Alternatively, plain and ordinary meaning, which is: “a method of concurrently treating Cushing’s syndrome and [distinguishing between different types of ACTH-dependent Cushing’s syndrome / obtaining a measurement to distinguish between different types of ACTH-dependent Cushing’s syndrome]”
The Court: Plain and ordinary meaning; no construction required.

(3) “a method of concurrently treating Cushing’s syndrome and obtaining a measurement indicative of differential diagnosis of adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome,” claim 18 of the ’495 Patent

Plaintiff’s: “a method of concurrently treating Cushing syndrome and [differentially diagnosing adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome / obtaining a measurement indicative of differential diagnosis of adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome] in order to recommend transphenoidal surgery or appropriate imaging to identify source of the ectopic ACTH secretion”
Defendants: Plain and ordinary meaning; no construction required. Alternatively, plain and ordinary meaning, which is: “a method of concurrently treating Cushing’s syndrome and [distinguishing between different types of ACTH-dependent Cushing’s syndrome / obtaining a measurement to distinguish between different types of ACTH-dependent Cushing’s syndrome]”
The Court: Plain and ordinary meaning; no construction required.

Naloxone - USA


On Jun. 22, 2020 in an unsealed opinion New Jersey court found Narcan® patents invalid as obvious over prior disclosure of claimed elements.

Adapt pharma / Opiant pharma (Plaintiffs) owns NDA for Narcan® (Naloxone, 4mg) Nasal Spray which was approved by USFDA on Nov. 18, 2015. Narcan is a branded nasal spray used to treat patients suffering from an opioid overdose. Teva (Defendant) filed ANDA with P-IV certification to market generic version of the drug. Plaintiffs sued Teva for infringement of patents, US 9,468,747 US 9,561,177, US 9,629,965 and US 9,775,838. Teva stipulated to infringement but asserted that patents-in-suit are invalid under obviousness. The Court held a two-week bench trial beginning on Aug. 26, 2019, and concluding on Sep. 6, 2019.

The asserted claims in the Patents-in-Suit relate generally to the pharmaceutical compounds, delivery methods, and devices used with Narcan. The compound consists of about 4.4mg of naloxone hydrochloride dihydrate, between about 0.005mg and about 0.015mg of benzalkonium chloride (“BZK”), between about 0.1mg and about 0.5mg of disodium edetate (“EDTA”), between about 0.2mg and about 1.2mg of sodium chloride, and an amount of acid sufficient to sustain a pH balance of 3.5–5.5 in about 100 microliters of solution. That solution is delivered into a single nostril of a patient by the Aptar Unit-Dose device.

Before the priority date of the patents certain things were known such dose of naloxone, excipients, device etc in different prior arts. The Court found the asserted claims of the Patents-in-Suit are obvious in light of the references such as Strang / Kulkarni / Djupesland combination. Strang discloses an intranasal form of naloxone formulated for the treatment of opioid overdoses. Strang noted that the volume of liquid delivered to the nostril should be less than 250 microliters and specifically preferred volumes of 50, 100, 150, and 200 microliters. The device described by Djupesland is filled with 125 microliters of solution and administers a dose consisting of 100 microliters of fluid, which is delivered in a single actuation. Strang states that “[i]t can be preferred to start with an amount equivalent to 4mg” of naloxone. Strang estimated that an intranasal dose of 3mg to 4mg would be bioequivalent to the FDA-approved 1mg injectable dose. As to the pH of the formulation, Strang prefers a pH that is less than or equal to 5.5, and Strang and Kulkarni specifically discuss using hydrochloric acid as an agent. As to the use of BZK as a preservative, Strang generally describes typical pharmaceutical excipients used in intranasal formulations. Kulkarni discusses specific preservatives that can be used to stabilize a nasal formulation in more detail and discloses a range of BZK with an upper limit of 0.119%. As to the use of EDTA, Kulkarni states a concentration of 0.5% of EDTA and describes using hydrochloric acid to adjust the pH of the formulation.

Alternatively, the Court found the asserted claims of the Patents-in-Suit are obvious in light of the Davies / Kerr 2009, Kerr Formulation / Bahal combination. Davies discusses formulations and devices that can be used to treat opioid overdoses and states that while intravenous administration is the standard method of administering naloxone, it poses significant difficulties in the community setting where naloxone is likely to be administered by individuals lacking medical training. It teaches that intranasal naloxone “can be given quickly and effectively without the need for the first-aider to find a blood vessel and give an intravenous injection.” As to the dose of naloxone, Davies describes a range of 0.2mg to 5.0mg as being appropriate. As to a tonicity agent, the Kerr Formulation used sodium chloride. Both Davies and Kerr discuss a sodium chloride concentration between 0.2 to 1.2mg per 100 microliters of solution. Bahal preferred formulations that included sodium chloride as a tonicity agent and hydrochloric acid to adjust the pH of the solution. The Kerr Formulation used BZK. Davies also states that formulation should have a slightly acidic pH and uses BZK as a preservative in one of his formulations. Bahal stated that the “addition of a chelating agent, such as [EDTA], to the commercial formulation prevents naloxone degradation, even in the presence of oxygen and after autoclaving.” Bahal preferred a range of 0.0001% to 1.0%.

Intranasal Naloxone Was Known to Be Safe and Efficacious, and Was Widely Used Prior to March 16, 2015:

Court said that intranasal naloxone was known to be safe and efficacious, and was widely used before priority date of the invention. Naloxone was initially approved for the treatment of opioid overdoses in 1971 as an injection. It was known to be “an extremely safe drug” and it was known in the prior art that naloxone could be administered intranasally. Intranasal administration was popular in the community setting because it was needle-free and therefore did not pose the dangers associated with exposed needles that injectable naloxone did. To administer naloxone intranasally, individuals utilized a MAD Kit which consisted of a mucosal atomizer and a syringe of naloxone solution that had to be assembled prior to use. The MAD Kit was FDA-approved to deliver injectable formulations intranasally. When used to administer naloxone, the MAD Kit had numerous drawbacks which were well known to a POSA. Therefore, POSA would have looked to another device. The Aptar UnitDose Device used in Narcan® is an FDA-approved device that administers intranasal medications in 100 or 200 microliter volumes. The Aptar device was commercially available prior to March 16, 2015, and was not invented by the inventors of the Patents-in-Suit. The shortcomings of the MAD Kit were discussed at the 2012 FDA Meeting, with one physician noting that the administration of naloxone “could be improved with a one-step affordable FDA-approved intranasal delivery device.” A POSA, therefore, would have been motivated to select a Aptar device that was as easy to use.

The Prior Art Does Not Teach Away from a Higher Dose of Naloxone or Using BZK With Naloxone:

Court said that a POSA would have thought a 4 milligram intranasal dose was safe and would have preferred a higher initial dose of naloxone in the community setting. The prior art indicated that naloxone could be administered safely in a doses of 0.5mg to 20mg. Among the initial doses recommended by Strang was an initial dose of 4mg. When FDA conducted meeting in 2012 the purpose was “to promote or encourage the industry to develop an intranasal naloxone product that could be FDA-approved.” The FDA noted that they were not overly concerned about the safety implications of a higher dose of naloxone because it is known to be a relatively safe drug. Prior to March 2015, a POSA would have known that naloxone has a lower bioavailability when administered intranasally compared to when it is administered in an injectable dose because an intranasal dose must first be absorbed through the nasal mucosa prior to be absorbed into the bloodstream. Intranasal naloxone, therefore, requires a higher dose of naloxone to achieve the same bioavailability as an intravenous dose. Prior to March 2015, a POSA would have known that a layperson using a MAD Kit to administer a 2mg dose of intranasal naloxone had to re-dose nearly half of the time (noting that 48% of cases in the study required a second 2mg dose of naloxone). Also the 4mg intranasal doses of naloxone were administered via a MAD Kit to reverse the effects of higher potency opioids. Moreover, a POSA would have known that the benefits of a higher initial dose outweighed the concerns about withdrawal side effects.

The Inclusion of BZK, EDTA, Hydrochloric Acid, and Sodium Chloride was obvious:

Court said that a POSA who was developing an intranasal naloxone product would have been motivated to optimize prior MAD Kit formulation for nasal delivery. Strang noted that “[t]ypical pharmaceutical excipients used in intranasal formulations are known to the skilled person and can be used for the formulations according to the present invention. Adapt argued the prior art, particularly Wyse, taught away from using BZK as a preservative in intranasal naloxone formulations and, therefore, a POSA would have not have been motivated to select it for their formulation. Court, however, found this argument unconvincing. Court said that the concentration of BZK used by Wyse was significantly higher than the amount used in every other FDA-approved intranasal product. Wyse used a formulation containing a 0.125% concentration of BZK, which is 8.5 times higher than the concentration used in the Patents-in-Suit. A POSA would have understood from Wyse that high concentrations of BZK can cause naloxone to degrade but would not have been dissuaded from using BZK in naloxone formulations in a lower dose. Therefore, in light of the testimony given at trial and the exhibits entered into evidence, the Court found by clear and convincing evidence, that before the priority date of the Patents-in-Suit, a POSA would have optimized naloxone for intranasal administration and found it obvious to use sodium chloride, hydrochloric acid, BZK, and EDTA. Thus, a POSA would have been motivated to combine strang / kulkarni / djupesland and davies / kerr 2009, kerr formulation / bahal and would have had a reasonable expectation of success.

Finally, Court also found that Plaintiffs failed to show any secondary considerations of nonobviousness to support patentability sufficient to overcome teva’s prima facie showing of obviousness.

CLENPIQ® - USA


On Jun. 22, 2020 Delaware Court granted Defendants’ Motion for Judgment on the Pleadings & did not find induced infringement of method of administration claims.

Civil Action No.   : 19-913
Plaintiffs               : Ferring Pharmaceuticals Inc. et al
Defendants          : Lupin Inc. et al

Before the Court is Defendants’ Motion for Judgment on the Pleadings pursuant to Federal Rule of Civil Procedure 12(c) for failure to state a claim upon which relief may be granted.

Background:

Plaintiffs filed this action on May 16, 2019, alleging infringement of U.S. Patent Nos. 9,827,23 and 9,669,110. The instant action is in response to Defendants filing an ANDA seeking FDA approval for a generic of Plaintiffs’ product, CLENPIQ® (sodium picosulfate, magnesium oxide, and anhydrous citric acid) Oral Solution. The ’231 patent claims a composition of sodium picosulfate, magnesium oxide, citric acid, and malic acid and methods for making and using the composition. The ’110 patent claims a method of timing a colonoscopy procedure. Only the ’110 patent is at issue in Defendants’ motion for judgment on the pleadings.

Claim 1 of the ’110 patent recites:

1. A method of timing a colonoscopy procedure performed on a patient in need thereof, comprising: administering a picosulfate bowel composition to the patient; and performing the colonoscopy procedure from about 3 hours to about 1 hour after the administration of the picosulfate bowel composition.

CLENPIQ® is indicated “for cleansing of the colon as a preparation for colonoscopy in adults.” The CLENPIQ® label describes a “Split-Dose Dosage Regimen,” which instructs:
First dose: administer during evening before the colonoscopy.
Second dose: administer the next day, during the morning prior to the colonoscopy.

The full prescribing information for the Split-Dose method for “second dose” reads:

Dose 2 – Next morning on the day of colonoscopy (start approximately 5 hours prior to colonoscopy):
• Continue to consume only clear liquids (no solid food or dairy).
• Take the second dose (the second bottle) of Sodium Picosulfate, Magnesium Oxide, and Anhydrous Citric Acid Oral Solution.
• Following the Sodium Picosulfate, Magnesium Oxide, and Anhydrous Citric Acid Oral Solution dose, drink at least three 8-ounce cups (cup provided) of clear liquids (24 ounces) at least 2 hours before the colonoscopy.

Court’ analysis:

Plaintiffs alleged that physicians and patients who use Defendants’ ANDA product in accordance with its label will directly infringe the claims of the ’110 patent by “performing the colonoscopy from about 3 hours to about 1 hour after administration of the picosulfate bowel composition.” Thus, Plaintiffs claim that Defendants will indirectly infringe the ’110 patent under 35 U.S.C. § 271(b) by inducing physicians who prescribe picosulfate solution, or patients who take it, to directly infringe. Defendants argued that Plaintiffs’ “complaint fails to state a claim [for induced infringement] because [Defendants’] ANDA label does not encourage, recommend, or promote anyone to perform the claimed use” of the ’110 patent. Regarding Dose 2, Defendants argued that because the label instructs physicians and patients to see the full prescribing instructions, and the full prescribing instructions direct that the 5.41-fluid ounce dose should be started “approximately 5 hours prior to colonoscopy,” the label therefore does not “encourage, recommend, or promote” that Dose 2 be taken less than 3 hours before the colonoscopy. Defendants continue that, even if “a patient could still be drinking the 5.41-fluid ounce dose within three hours of the colonoscopy” because the label is interpreted to “describe” or “permit” this use, the label does still not rise to the level of inducement because it is not encouraging, recommending, or promoting such use. Defendants claim that Plaintiffs cannot “create a material issue of fact” by asserting that it is possible for doctors and patients to infringe without showing that the label promotes or encourages that possible infringement.

Court agreed with Defendants & said that on its face, the label does not instruct that the Dose 2 picosulfate solution be administered less than 3 hours and more than 1 hour before the colonoscopy procedure. The label states that Dose 2 should be taken the “next day, during the morning of the colonoscopy.” It is a broad guideline for safe and effective timing of the second dose. The final step of the Split-Dose Regimen instructs that the patient should drink at least 24 ounces of clear liquid following the picosulfate solution but “at least 2 hours before the colonoscopy.” Logically, the instruction for the final step would require consumption of the picosulfate solution more than 2 hours before the colonoscopy. That instruction therefore cannot be interpreted as encouraging, recommending, or promoting consumption of the picosulfate solution less than 3 hours before the colonoscopy. The only reasonable reading of the full prescribing instructions is that they say to take the picosulfate solution no more than 5 hours before the colonoscopy and to finish it no later than 2 hours before the colonoscopy. The mere fact that the label may permit an infringing use is insufficient to show inducement, regardless of whether that fact is alleged in the complaint or stated later by an expert. See HZNP Medicines, 940 F.3d at 702. Thus, Defendants’ label cannot be the basis for a finding of any affirmative action or intent to induce infringement. Therefore Defendants’ label does not induce infringement of the ’110 patent.

Dimethyl fumarate – USA


On June 18, 2020, District Court of West Virginia found method of use patent covering Tecfidera® invalid for lack of written description support.

Background:

Biogen is the owner of US 8,399,514 patent entitled, “treatment for multiple sclerosis” expiring in Feb. 2028. This patent is listed in Orange Book for the product, Tecfidera® (Dimethyl fumarate) DR capsules. Biogen is the NDA holder & markets this product in USA.  Mylan sought approval of generic version & thus filed ANDA containing P-IV certification with USFDA to US’514 patent. Biogen sued Mylan within statutory period. Mylan also filed IPR in PTAB against same patent in Jul. 2018. PTAB issued final written decision in Feb. 2020 finding challenged claims not obvious over cited prior arts. Therefore, Mylan dropped obviousness challenge in district court & focused on lack of written description support under 35 U.S.C 112.

The independent claim 1 reads:

1. A method of treating a subject in need of treatment for multiple sclerosis comprising orally administering to the subject in need thereof a pharmaceutical composition consisting essentially of (a) a therapeutically effective amount of dimethyl fumarate, monomethyl fumarate, or a combination thereof, and (b) one or more pharmaceutically acceptable excipients, wherein the therapeutically effective amount of dimethyl fumarate, monomethyl fumarate, or a combination thereof is about 480 mg per day.

Court’s analysis:

Mylan argued that the ’514 Patent is invalid for lack of written description because the specification described in 2007 (priority date) bears no resemblance to the invention claimed in 2011. Specifically, at the time of filing POSA would not have expected the claimed invention——a 480mg/day dose of DMF (BID)——to effectively treat MS  and secondly when viewed as an integrated whole, the combination of selectively-plucked disclosures in the specification of the ’514 Patent fails to sufficiently describe the claimed invention. According to Mylan, it is only after Phase III trial in 2011 Biogen came to know the effectiveness of 480[mg/day] dose. Before the priority date of patent, only phase II results were known & that disclosed 720[mg/day] dose as effective dose to treat MS.

Court agreed with Mylan based on the facts, expert testimony & held that specification does not demonstrate that the Inventors “Possessed” the claimed invention at the time of filing of application. Court said that in order to satisfy the written description requirement of § 112, the inventor must “‘convey with reasonable clarity to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention, and demonstrate that by disclosure in the specification of the patent.’” Nuvo Pharm., 923 F.3d at 1376 (cleaned up) (citation omitted). Significantly, “actual ‘possession’ or reduction to practice outside of the specification is not enough.” Ariad Pharm. Inc., 598 F.3d at 1352. “[I]t is the specification itself that must demonstrate possession.” Court said that the specification of the ’514 Patent begins with a general discussion of MS but quickly turns to a discussion of how “the Nrf2 pathway may be activated in neurodegenerative and neuroinflammatory diseases as an endogenous protective mechanism.” The specification then provides five methods for screening of the compounds. Biogen argued that, “the ’514 Patent links through Method 4 each of the three recited elements of the asserted claims: (1) a method of treating MS with (2) DMF and/or MMF (3) at a dose of 480 mg per day.” But court said that Method 4 is limited in scope and makes no mention of treating MS with a 480mg/day dose of DMF (BID). Bioge then pointed out following paragraph from specification & argued that it provides support for the 480mg/day dose:

“For example, an effective dose of DMF or MMR to be administered to a subject orally can be from about 0.1 g to 1 g per pay [sic], 200 mg to about 800 mg per day (e.g., from about 240 mg to about 720 mg per day; or from about 480 mg to about 720 mg per day; or about 720 mg per day). For example, the 720 mg per day may be administered in separate administrations of 2, 3, 4, or 6 equal doses”.

Court said that this passage, however, neither “links” this “effective dose” to the treatment of MS, nor to a 480mg/day dose of DMF (BID). 480mg dosing is mentioned only once in this paragraph. Moreover, based on the results of Biogen’s Phase II study, as of the claimed priority date of February 8, 2007, a POSA would have known that 720mg/day of DMF (TID) is a therapeutically effective dose for treating MS, and that lower doses, such as 360mg/day of DMF (TID) and 120mg/day of DMF (QD), are not. Thus, on reading the specification, a POSA would be drawn to the 720mg/day dose of DMF because of its specific disclosure & not to 480mg dose. Moreover, this paragraph only discloses DMF & its dose. It does not discloses treatment of MS. Specification provides an exhaustive list of diseases that can be treated. Therefore, the method 4 can be used for a plethora of neurological diseases, and there are no “blaze marks” that would lead a POSA specifically to MS. Moreover, Biogen’s expert, Dr. Wynn, conceded on cross examination. Based on his reading of the ’514 Patent, he testified that he would not know which dose provided in this paragraph would be most effective for treating MS.

Biogen’s reliance on Example 3 fares no better which is an Experimental Autoimmune Encephalomyelitis (“EAE”) animal model used for MS. Dr. Wynn never explained how this experiment teaches a method of treating MS (in humans, not mice) with a therapeutically effective amount of DMF, i.e., 480 mg/day (BID). On the contrary, Dr. Lukashev credibly testified that the three examples in the ’514 Patent were part of his research, which “was separate from preclinical development” and unrelated to the clinical application of DMF in MS. Indeed, the results of Example 3 “provided evidence of [MMF] and [DMF] activation of NRF2 in vivo.”

Moreover, extrinsic evidence confirms the lack of written description. After getting the surprising results from phase III in 2011, Biogen filed different patent application (US 14/119,373) specifically covering the methods of treating Multiple Sclerosis with 480 mg/day dose. The specification provided and discussed in detail a wealth of data generated during Biogen’s Phase III study.  In contrast, the specification in the ’514 Patent included none of this data or information. But because of priority of May 2011, US’373 application would have faced strong invalidity challenges because of the ample availability of prior arts. Therefore, Biogen amended its title and claims of the US 12/526,296 application (parent of US’514 patent, now abandoned) without amending specification so that it can claim priority date of Feb. 2007. This strategy came with a cost, however, since Biogen was left with a specification written in 2007 that bore no resemblance to the ’514 Patent’s title and claimed invention——a method of treating MS with a therapeutically effective amount of DMF, i.e., 480mg/day —an invention that no one knew would work until April 2011 when Biogen received the results of its Phase III study.

Court said that, in sum, Biogen has attempted to satisfy the written description requirement of § 112 by selectively plucking specific words from the specification that correspond to each element of the claimed invention. The Federal Circuit has squarely rejected this approach. [Nuvo Pharm., 923 F.3d at 1380]. The ’514 Patent thus must be viewed as an integrated whole rather than a sum of its parts. As of February 8, 2007, inventors did not “possess” the claimed invention——a method of treating MS with a therapeutically effective amount of DMF, i.e., 480mg/day (BID) & thus Mylan has established by clear and convincing evidence that the asserted claims of the ’514 Patent are invalid for lack of written description.

Pemetrexed – Netherlands


On Jun. 12, 2020, Supreme Court of Netherlands followed Advocate General’s Opinion and upheld preliminary injunction (PI) decision of lower court by dismissing the appeal.

The heart of the issue was the scope of the EP (NL) 1313508 patent which is held by Lilly. The patent entitled, “Combination containing an antifolate and methylmalonic acid lowering agent”. This second medical indication patent claims treatment of cancer with pemetrexed disodium in combination with vitamin B12 & folic acid. The patent is valid in the Netherlands until Jun. 14, 2021. Lilly markets the medicine Alimta® (Pemetrexed disodium). The active ingredient in Alimta® (after solution) consists of pemetrexed anions. In Alimta®, the anions are bound to sodium ions to form the pemetrexed disodium salt. The active substance in Fresenius Kabi's Pemetrexed for injection is Pemetrexed diacid with tromethamine instead of Pemetrexed disodium as in Alimta 100 mg / 500 mg powder for concentrate for solution for infusion. When reconstituted and diluted for administration, the active moiety remains the same irrespective of the salt form. The marketing authorization for Pemetrexed Fresenius was granted on July 22, 2016.

On Aug. 03, 2017 Lilly has claimed an infringement prohibition & argued that Pemetrexed Fresenius falls under the scope of protection of EP 508. Preliminary Relief Judge of the District Court of The Hague on Oct 24, 2017 issued an injunction against Fresenius Kabi’s pemetrexed product.  Court of Appeal of The Hague on May 08, 2018 affirmed the decision. Fresenius then appealed the decision. Advocate General Van Peursem provided opinion on Apr. 01, 2020 on the said matter. The actual assessment was done to see whether Pemetrexed Fresenius falls within the equivalent scope of protection of EP 508. Specifically, the question was whether the limitation of the claims introduced by Lilly during prosecution could preclude infringement under equivalence. During prosecution Lilly amended claims from antifolate to pemetrexed disodium. AG opined that in the eyes of the average skilled person, there is no conscious choice based on a technical reason, which would lead them to understand that the intention here is to claim only the disodium salt. According to the court, this technical choice cannot be deduced from the description by the person skilled in the art nor does the person skilled in the art read any indications that a salt study was carried out on which the choice for disodium salt. The average skilled person would see that disodium was just a suitable salt form. The disodium salt was only mentioned because it already existed (Alimta). The professional does not see such a deliberate limitation as intended by Fresenius on the basis of his general professional knowledge.

Moreover, the inventive idea of EP 508 lies in the use of vitamin B12 and optional folic acid in combination with the antifolate pemetrexed (not limited to pemetrexed disodium), thereby reducing the serious toxic side effects of the pemetrexed anions while the efficacy of the pemetrexed anions in the inhibition of tumor growth is maintained. The person skilled in the art knows that only the anion is responsible for the efficacy (and toxicity) of pemetrexed, he also finds confirmation for the insight that the invention relates rather to the active form of pemetrexed after administration and not to the specific disodium salt form disclosed therein , in the description of the mouse model.

Court of Appeal correctly considered that amendment to claims made during the granting procedure at the direction of the Examiner does not prevent a patent holder from relying on the application of Article 2 of the Protocol (equivalence) when determining the scope of protection. Claims were amended to avoid Art. 123(2) rejection (added matter) raised by Examiner. Added matter and scope of protection are clearly distinguishable issues. A limitation of the claims under Article 123 paragraph 2 EPC would result in the patent holder never being able to claim protection of equivalents. This could lead to too limited scope of protection.

Therefore, the appeal in cassation was dismissed & PI upheld.

Dapsone – USA


On June 04, 2020, Federal Circuit denied Almirall’s request for attorney fees pursuant to 35 U.S.C. § 285.

Background:

Amneal filed IPRs against US 9,161,926 and US 9,517,219 patents in Feb. 2018 and in Oct. 2018 respectively. These patents are listed  in Orange Book for ACZONE® (dapsone) 7.5% topical gel. In Feb. 2019, Amneal filed ANDA with the FDA, submitting Paragraph IV certifications for the ’219 patent and the ’926 patent. Almirall sued amneal for infringement of ’219 patent only. Therefore, Amneal filed a counterclaim seeking declaratory judgment that the ’926 patent is invalid and is not infringed. After that parties engaged in settlement discussions between Apr. 22  - Apr. 29, 2019. It appeared that Almirall offered covenant-not-to-sue on the ’926 patent contingent on dismissal of this IPR. But the final settlement was not reached & in Aug. 2019 PTAB issued final written decision finding claims 1–6 of the ’926 patent not unpatentable. Amneal filed appeal on Oct. 28, 2019 & on Mar. 30, 2020, Amneal filed motion to voluntarily dismiss its appeal. Almirall thus sought attorney fees pursuant to 35 U.S.C. § 285. Almirall argued that Amneal litigated this matter in an unreasonable manner by continuing to litigate the IPR after the covenant-not-to-sue was offered, and Almirall had asked the FDA to remove the patent from the Orange Book. Almirall sought only fees and costs incurred during the relatively marginal window of time from [April 29, 2019], the date settlement negotiations were terminated, to the date of trial in the underlying IPR [June 5, 2019].

Court’s analysis:

Almirall specifically argued that Federal Circuit is authorised to award attorney fees in an appeal lies from the decision of PTAB. But, Federal Circuit disagreed & said that this court can award attorney fees under section 285 for work done in district court patent infringement actions. Appeals from the Board are a different matter as these are administrative proceedings. Moreover, the plain meaning of section 285’s reference to “[t]he court” speaks only to awarding fees that were incurred during, in close relation to, or as a direct result of, judicial proceedings. Though in some cases court has awarded attorney fees but these cases are different from present one. It is true that in Sullivan (Sullivan v. Hudson, 490 U.S. 877; 1989), the Supreme Court explained that fees could be awarded for administrative proceedings that are “intimately tied to the resolution of the judicial action and necessary to the attainment of the results Congress sought to promote by providing for fees.” But the “narrow class of qualifying administrative proceedings” that Sullivan was referring to were those “where ‘a suit has been brought in a court,’ and where ‘a formal complaint within the jurisdiction of a court of law’ remains pending and depends for its resolution upon the outcome of the administrative proceedings.” In another case, PPG (PPG Indus., Inc. v. Celanese Polymer Specialties Co., 840 F.2d 1565, 1569; Fed. Cir. 1988), this court allowed for the award of fees where Patent Office “proceedings substituted for the district court litigation on all issues considered by the PTO and the Board.” But it did so only with respect to fees incurred after the filing of a civil action, and the fees were awarded in that district court proceeding. The Patent Office proceedings were found by the district court to be intimately tied to the resolution of that action. Those are clearly not the circumstances here.

For these reasons, Federal Circuit rejected Almirall’s request for attorney fees under section 285.

Melatonin - UK


On Jun 03, 2020, UK high court denied Claimants, Neurim & Flynn’s application for interin injunction against Mylan.

Background:

Neurim owns patent, EP(UK) 1441702 which claims prolonged release pharmaceutical formulations of melatonin to improve the restorative quality of sleep in a patient suffering from primary insomnia characterised by non-restorative sleep. Flynn is the exclusive licensee under the Patent. The pharmaceutical formulation claimed by the Patent is sold under the brand name Circadin. More recently, Neurim has developed a paediatric version of prolonged release melatonin, Slenyto. The Patent is a “second medical use” patent & will expire on 12 August 2022. This patent was granted by EPO in May 2017 & was subsequently opposed by various opponents including Mylan. Patent was revoked by the EPO Opposition Division via written decision on 2 January 2020. Mylan intend to market a “generic” rival to Circadin as it got marketing authorisation in Dec. 2019.

Neurim and Flynn commenced proceeding for infringement and injunctive relief. Mylan counterclaims for revocation of the Patent on grounds of anticipation, obviousness and insufficiency. An expedited trial had been ordered, which is due to take place in a 5-day window floating from 26 October 2020. Hearing was held on the issue of interim injunction from May 20, 2020 to Jun 03, 2020.

Court’s analysis:

Neurim and Flynn argued that if an interim injunction were not granted, their losses would fall to be categorised under two broad heads, Period 1 (from hearing till trial i.e. from Jun. 2020 to Dec. 2020) and Period 2 (after trial till patent expiry i.e. Dec. 2020 to Aug. 2022). Mylan counterargued that the market would recover if Neurim and Flynn succeeded at trial and obtained a permanent injunction in Dec. 2020.

During hearing court heard both the parties & their respective submissions. Court said that the starting point for the current issue of interlocutory relief is the judgment given by Lord Diplock in “American Cyanamid Co v. Ethicon Ltd.” The court must weigh one need against another and determine where “the balance of convenience” lies. The balance of convenience involves a number of steps:.

Stage 1: A serious issue to be tried?

The applicant for interim relief, the claimant, must show that there is a “serious issue to be tried”.  Court said that looking simply at the issues in the proceedings, there is serious issue to be tried as to the validity of the Patent. In his oral submissions before me, Mr Vanhegan, QC, for Mylan, accepted that there was a serious issue to be tried.However, Mylan relied on the fact that the Patent had been revoked by the EPO Opposition Division in support of its contention that there was no serious issue to be tried. Mylan also argued that an interim injunction was refused in other jurisdictions. Court, however, said that in some cases, the decisions of courts of foreign jurisdictions or EPO are entitled to great weight but this is not one of those cases. The decisions of the these authorities are not binding on us.

Stage 2: Are damages an adequate remedy to the claimant?

If damages were an adequate remedy, a claimant should not obtain an interim injunction, even if the claim was very strong. Mylan contended that – even if, court found for the purposes of this application, the harm to Neurim and Flynn would extend beyond the period of competition between Circadin/Slenyto and the Generic Product in Period 1 – damages would nevertheless be an adequate remedy. Court agreed with Mylan and said that damages will prove to be an adequate remedy to both Neurim and Flynn for the following reasons:

    1.The general measure of damages in a patent infringement case is clearly stated. It is the standard tortious measure, the calculation of which was articulated in “Livingstone v. The Rawyards Coal Company”.

    2. Court see no reason why Neurim and/or Flynn’s losses during both Period 1 and Period 2 cannot properly be calculated. Clearly, Neurim and Flynn will have records of their sales to date of Circadin and Slenyto, and they will continue to keep such records. Equally, there is no difficulty in Mylan maintaining and (for the purposes of trial) providing to Neurim and Flynn records of its sales of the Generic Product.

    3. All of these losses/profits can be calculated by reference to information that is or will be in the hands of Neurim, Flynn & Mylan.

Stage 3: If damages are not an adequate remedy to the claimant, consider the adequacy of the undertaking in damages to the defendant?

If damages are an adequate remedy to the claimant, then the inquiry stops at Stage 2. However, the converse does not hold good. Court said that the question is whether Mylan’s loss, in being deprived of the opportunity of competing in the market for Circadin and Slenyto, is capable of being adequately compensated for in damages. Court said that Neurim and Flynn are prepared to offer the undertaking in damages; and that Neurim and Flynn are in a financial position to make good on that undertaking if called upon to do so. At first sight, just as in the case of Neurim and Flynn, this appears to be simply a case where damages can adequately be assessed. Instead of calculating what Neurim and Flynn lose by reason of Mylan’s competition, it is necessary in Mylan’s case to calculate what Mylan has failed to gain in being deprived of this opportunity. That said, there are a number of factors that render this assessment of damages more difficult. Therefore, it would be materially harder to assess Mylan’s loss than that of Neurim or Flynn.

Stage 4: no adequate remedy for either side

A court must consider all relevant factors when granting a discretionary remedy like an interim injunction. Court said that it already concluded that damages would be an adequate remedy for Neurim and Flynn, and a less adequate remedy for Mylan. Court said that it would merely go so far as to say that any award of damages to Mylan would be materially more uncertain than calculating Neurim and Flynn’s loss.

Court thus declined to grant interim injunction.
