The related patents claim priority from a 1998 application and concern drugs for treatment of spinal nerve injuries, often associated with herniated discs. Between spinal vertebrae are soft “spinal discs,” that permit the spine to flex and move by absorbing and distributing compressive forces. A spinal disc becomes herniated when tissue surrounding it tears and nucleus pulposus, normally inside the disc, leaks into the epidural space of the spine. Nucleus pulposus secretes TNF-α, a powerful signaler of inflammation and other injuries. The nerve roots that extend from the spinal cord pass through the epidural space; if they come into contact with TNF-a, back pain or numbness may result. Nerve root injuries may be reduced or eliminated by “inhibiting” the TNF-α. Tobinick brought an interference proceeding. The Patent Trial and Appeal Board dismissed, construing “administered locally” as administering the claimed therapeutic compound “directly to the site where it is intended to act, that is, to the location where the nucleus pulposus is causing the symptoms of the nerve disorder.” The Board found that Tobinick’s patent application did not contain written description support so that he lacked standing to bring the interference. The Federal Circuit reversed, finding that Tobinick’s application contained sufficient written description support for local administration; it describes administering the therapeutic compound to the epidural space adjacent to a herniated spinal disc, which is the site where it is intended to act and the location where the nucleus pulposus is causing symptoms of the nerve disorder.

Monsanto developed a genetic modification in soybean seeds (Roundup Ready® (RR)), known as the 40-3-2 event (RR trait), which enables soybean plants to tolerate application of glyphosate herbicide to kill weeds. Monsanto owns the patent for the RR trait and granted Pioneer a license to produce and sell seeds containing the traits. After Pioneer became a subsidiary of DuPont, Monsanto and Pioneer entered into an amended license, under which DuPont produced and sold RR trait seed. In 2006, DuPont announced that it had developed a glyphosate-tolerant trait, OGAT, expected to confer tolerance to both glyphosate and acetolactate synthase inhibitor herbicide. Testing indicated that OGAT alone did not provide sufficient glyphosate-tolerance for commercial use. DuPont then combined OGAT with the RR trait; the OGAT/RR stack provided increased yields in field trials. DuPont did not sell any OGAT/RR product, however, and discontinued development. Monsanto sued DuPont for breach of the license and patent infringement. The district court granted partial judgment to Monsanto, holding that the license was unambiguous and did not grant the right to stack non-RR technologies with the licensed” trait, but allowed DuPont to amend its answer to assert reformation counterclaims and defenses. The court ultimately told DuPont to “either voluntarily dismiss these reformation claims or produce … all documents … previously withheld.” DuPont continued litigating its reformation counterclaims and produced previously withheld internal e-mails that showed its awareness that it did not have the right to commercialize the OGAT/RR stack. The court found that DuPont’s position was not rooted in fact, that DuPont made misrepresentations and had perpetrated a fraud on the court, struck DuPont’s reformation defense and counterclaims, and awarded limited attorney fees to Monsanto. The Federal Circuit affirmed. View "Monsanto Co. v. E.I. du Pont de Nemours & Co." on Justia Law

The Drug Price Competition and Patent Term Restoration Act of 1984 (Hatch-Waxman Act), 21 U.S.C. 355(j)(2)(A)(vii)(IV) established procedures for identifying and resolving patent disputes between brand-name and generic drug manufacturers. One procedure requires a prospective generic manufacturer to certify to the FDA that any listed, relevant patent is invalid or will not be infringed by the manufacture, use, or sale of the generic drug (paragraph IV). Generic manufacturers filed paragraph IV applications for generic drugs modeled after Solvay’s FDA-approved, patented drug AndroGel. Solvay claimed patent infringement, 35 U.S.C. 271(e)(2)(A). The FDA approved the generic product, but the generic companies entered into “reverse payment” settlements, agreeing not to bring the generic to market for a number of years and to promote AndroGel to doctors in exchange for millions of dollars. The FTC sued, alleging violation of section 5 of the Federal Trade Commission Act by agreeing to abandon patent challenges, to refrain from launching low-cost generic drugs, and to share in Solvay’s monopoly profits. The district court dismissed. The Eleventh Circuit affirmed. The Supreme Court reversed and remanded, calling for application of a “rule of reason” approach rather than a “quick look.” Although the anti-competitive effects of the reverse settlement might fall within the exclusionary potential of Solvay’s patent, the agreement is not immune from antitrust attack. It would be incongruous to determine antitrust legality by looking only at patent law policy, and not at antitrust policies. The Court noted the Hatch-Waxman Act’s general pro-competitive thrust, facilitating challenges to a patent’s validity and requiring parties to a paragraph IV dispute to report settlement terms to antitrust regulators. Payment for staying out of the market keeps prices at patentee-set levels and divides the benefit between the patentee and the challenger, while the consumer loses. That a large, unjustified reverse payment risks antitrust liability does not prevent parties from settling their lawsuits; they may settle in other ways, e.g., by allowing the generic to enter the market before the patent expires without payment to stay out prior to that point.

Myriad obtained patents after discovering the precise location and sequence of the BRCA1 and BRCA2 genes, mutations of which can dramatically increase the risk of breast and ovarian cancer. The discovery enabled Myriad to develop medical tests for detecting mutations for assessing cancer risk. Myriad’s patents would give it the exclusive rights to isolate an individual’s BRCA1 and BRCA2 genes and to synthetically create BRCA composite DNA. The district court entered summary judgment, finding the patents invalid under 35 U.S.C. 101 because they covered products of nature. On remand following the Supreme Court’s decision, Mayo Collaborative Servs. v. Prometheus Labs, Inc., the Federal Circuit found both isolated DNA and composite DNA patent-eligible. The Supreme Court affirmed in part and reversed in part, noting that the case did not involve “method claims” for new applications of knowledge about the genes or the patentability of DNA in which the order of the naturally occurring nucleotides has been altered. A naturally-occurring DNA segment is not patent-eligible merely because it has been isolated, but composite DNA is patent-eligible because it is not naturally-occurring. Myriad did not create or alter the genetic information encoded in the genes or the genetic structure of the DNA. Even brilliant discovery does not alone satisfy the section 101 inquiry. Myriad’s claims are not saved by the fact that isolating DNA from the human genome severs chemical bonds that bind gene molecules together. The claims are not expressed in terms of chemical composition, nor do they rely on the chemical changes resulting from the isolation of a particular DNA section. Composite DNA, however, is not a “product of nature;” a lab technician unquestionably creates something new when introns are removed from a DNA sequence to make composite DNA.

Once the FDA has approved a brand manufacturer's drug, another company could seek permission to market a generic version pursuant to legislation known as the Hatch-Waxman Amendments. See Drug Price Competition and Patent Term Restoration Act of 1984, 98 Stat. 1585. The relevant statute at issue in this case provided that a generic company "may assert a counterclaim seeking an order requiring the [brand manufacturer] to correct or delete the patent information [it] submitted... under [two statutory subsections] on the ground that the patent does not claim... an approved method of using the drug." 117 Stat. 2452, 21 U.S.C. 355(j)(5)(C)(ii)(I). At issue in this case was whether Congress had authorized a generic company to challenge a use code's accuracy by bringing a counterclaim against the brand manufacturer in a patent infringement suit. The Court held that a generic manufacturer could employ this provision to force correction of a use code that inaccurately described the brand's patent as covering a particular method of using the drug in question. Therefore, the Court reversed the judgment of the Federal Circuit. View "Caraco Pharmaceutical Laboratories, Ltd. v. Novo Nordisk A/S" on Justia Law

The patent claims at issue covered processes that help doctors who use thiopurine drugs to treat patients with autoimmune diseases determine whether a given dosage level was too low or too high. The claims purported to apply natural laws describing the relationships between the concentration in the blood of certain thiopurine metabolites and the likelihood that the drug dosage would be ineffective or induce harmful side-effects. At issue was whether the claimed processes have transformed these unpatentable natural laws into patent-eligible applications of those laws. The Court concluded that they have not done so and that therefore the processes were not patentable. The steps in the claimed processes involved well-understood, routine, conventional activity previously engaged in by researchers in the field. At the same time, upholding the patents would risk disproportionately tying up the use of the underlying natural laws, inhibiting their use in the making of further discoveries. Therefore, the Court reversed the judgment of the Federal Circuit. View "Mayo Collaborative Services v. Prometheus Laboratories, Inc." on Justia Law

Dutasteride is useful in the treatment of androgen responsive diseases. Androgens are a class of hormones; testosterone is the major circulating androgen. Androgens are implicated in diseases including benign prostatic hyperplasia, prostate cancer, acne, male pattern baldness and hirsutism. In some target tissues, including prostate and skin tissue, testosterone produces certain effects by first being converted to dihydrotestosterone. Dutasteride inhibits the enzymes that catalyze the conversion, mitigating some of testosterone’s physiological effects. GSK markets Avodart® and Jalyn™, which contain dutasteride and are FDA-approved to treat benign prostatic hyperplasia. GSK’s patent covers dutasteride and any “pharmaceutically acceptable solvate thereof.” Defendants filed Abbreviated New Drug Applications under 21 U.S.C. 355(j), seeking FDA approval to market generic versions of the drugs. As authorized by 35 U.S.C. 271(e)(2), GSK sued for infringement. Defendants stipulated to infringement, but alleged that the asserted claims were invalid for anticipation, lack of utility, lack of enablement, and inadequacy of the written description. The district court construed “solvate” (of dutasteride), acknowledging considerable extrinsic evidence that, in the pharmaceutical field, “solvate” is limited to crystalline complexes, no matter how created, but concluded that the specification of this particular patent directly contradicted any such narrow usage. The Federal Circuit affirmed without addressing claim construction because no matter which construction is adopted, the term “solvate” involves no performance propertyView "GlaxoSmithKline LLC v.

Takeda owns patents that claim the formulation for the brand-name drug Prevacid® SoluTab,™ which contains the active ingredient lansoprazole, a proton pump inhibitor used to treat acid reflux. It is the only proton pump inhibitor available as an orally disintegrable tablet. A patient allows the tablet to disintegrate in his mouth, leaving behind thousands of granules which the patient swallows. The stated objective of the 994 patent is a formulation with granules small enough to avoid a feeling of roughness in the patient’s mouth upon disintegration. In 2010, Zydus filed an abbreviated new drug application (ANDA) with the FDA, seeking to manufacture a generic version of Prevacid® SoluTab.™ Takeda filed suit, alleging that the ANDA product infringed claims of several patents. Only claim 1 of the 994 patent remains at issue. Zydus counterclaimed, alleging that claim 1 was invalid for failure to comply with 35 U.S.C. 112. The district court construed the claim term “fine granules having an average particle diameter of 400 μm or less,” accepting Takeda’s argument that the term should be construed to include a deviation of ±10%, based on a “universally accepted” 10% standard of error for particle size measurements. The Federal Circuit reversed the finding of infringement and found no invalidity. View "Takeda Pharm. Co., Ltd. v. Zydus Pharm. USA, Inc." on Justia Law

Proveris owns the 400 patent, for a mechanism to evaluate aerosol spray plumes. The apparatus evaluates delivery of drugs by inhalers or nasal sprays, by triggering a spray and collecting data on the plume with an illumination device and an imaging device. Innova made and sold the Optical Spray Analyzer (OSA). Proveris sued, alleging that OSA infringed the 400 patent. Innova conceded infringement of certain claims (including claim 3), but disputed infringement of others. The district court ruled in favor of Proveris on invalidity. A jury found that Innova did not infringe the disputed claims and that no damages had been proven. Based on the conceded infringement, the district court enjoined Innova from making or selling OSA. Innova modified OSA and began selling the new Aerosol Drug Spray Analyzer (ADSA). Proveris filed a contempt motion. Innova argued that OSA allowed a user to identify what range of images he wanted to analyze before activating the spray, while ADSA requires the user to first activate the spray and later determine what he wants to analyze. The district court ruled that, because Innova could have raised claim construction issues in the underlying infringement action, the court would not construe claim 3; Innova could not raise new invalidity arguments in contempt proceedings. The court entered a contempt order against Innova, found that the violation had been willful, and ordered disgorgement of profits. The Federal Circuit vacated, holding that the court erred in failing to construe the disputed claim language. View "Proveris Scientific Corp. v. Innovasystems, Inc." on Justia Law

The products at issue in this appeal are formulations of Athena’s RevitaLash, all of which contain a prostaglandin derivative as an active ingredient. The FDA has not taken enforcement action against, or otherwise regulated, the products. Allergan sells a product called Latisse, which also contains a prostaglandin derivative. Latisse is an FDA-approved prescription drug used for the treatment of a condition that affects eyelash growth. Allergan sued Athena for patent infringement and a violation of the Unfair Competition Law (UCL), California Business and Professions Code 17200 by violating California’s Health and Safety Code 1115501 by “marketing, selling, and distributing [its] hair and/or eyelash growth products without [a new drug] application approved by the FDA or California State Department of Health Services.” The district court rejected Athena’s claim that the Federal Food, Drug, and Cosmetic Act preempts Allergan’s UCL claim and granted Allergan an injunction on its claim that the products at issue qualify as new drugs that lack the requisite approval. The Federal Circuit vacated and remanded. The FDCA did not preempt Allergan’s UCL claim and there is no genuine dispute that the products are drugs under California law, but the injunction was overbroad. View "Allergan, Inc. v. Athena Cosmetics, Inc." on Justia Law
