Natural owns patents relating to dietary supplements containing beta-alanine (an amino acid). Together with histidine, another amino acid, beta-alanine can form dipeptides that are involved in the regulation of intracellular pH during muscle contraction and development of fatigue. Variations in dipeptide concentrations affect the anaerobic work capacity of athletes. One dipeptide, carnosine, contributes to hydronium ion buffering. During certain sustained exercise, hydronium ions and lactate can accumulate and severely reduce intracellular pH; reduced pH interferes with the creatine-phosphorylcreatine system, part of the process by which energy is generated in muscle cells. Natural's patents generally relate to the use of beta-alanine in a dietary supplement to “increas[e] the anaerobic working capacity of muscle and other tissue.” The district court applied the Supreme Court’s 2015 two-part “Alice” test and held all of the asserted claims were directed to patent ineligible subject matter (35 U.S.C. 101_ and lacked an inventive concept. The Federal Circuit reversed. Under Natural’s proposed claim constructions, the Method Claims are not directed to an exception to section 101 under the first step of the Alice test, so judgment on the pleadings was inappropriate. The Product Claims contain a dietary supplement limitation, with the same proposed construction, which does not support the idea that this limitation was well-understood, routine, and conventional. The Manufacturing Claims are not directed to the natural law or product of nature, but are an application of the law and new use of that product. View "Natural Alternatives International, Inc.. v.

Drug manufacturers filed Abbreviated New Drug Applications with the Food and Drug Administration seeking to market generic versions of Saphris, a drug product sold by Forest Laboratories. Saphris is a sublingually administered, atypical antipsychotic containing asenapine maleate. Forest sued for patent infringement, asserting that the proposed generic products would infringe claims of its patents. The district court held the generic manufacturers had not established certain claims to be invalid and held Forest had not established infringement of certain claims as to two manufacturers. The Federal Circuit vacated and remanded the validity determination, and for reconsideration infringement under a corrected claim construction. The district court erred in treating “excitation” as being limited to “excitation disorders.” The court rejected claims concerning sufficient written description, obviousness, and the construction of other claims.

Shire manufactured and marketed the lucrative drug Vancocin, which is used to treat a life-threatening gastrointestinal infection. After Shire learned that manufacturers were considering making generic equivalents to Vancocin, it inundated the Food and Drug Administration (FDA) with allegedly meritless filings to delay approval of those generics. The FDA eventually rejected Shire’s filings and approved generic equivalents to Vancocin. The filings resulted in a high cost to consumers. Shire had delayed generic entry for years and reaped hundreds of millions of dollars in profits. Nearly five years later, after Shire had divested itself of Vancocin, the Federal Trade Commission (FTC) filed suit against Shire under Section 13(b) of the Federal Trade Commission Act, 15 U.S.C. 53(b), seeking a permanent injunction and restitution, and alleging that Shire’s petitioning was an unfair method of competition. The district court dismissed, finding that the FTC’s allegations of long-past petitioning activity failed to satisfy Section 13(b)’s requirement that Shire “is violating” or “is about to violate” the law. The Third Circuit affirmed, rejecting “the FTC’s invitation to stretch Section 13(b) beyond its clear text.” The FTC admits that Shire is not currently violating the law and did not allege that Shire is about to violate the law.

The Bristol-Myers Squibb (BMS) patent, entitled “Stable Protein Formulations,” describes and claims specific fluid formulations an immunosuppressive agent used in the treatment of immune system disorders such as rheumatoid arthritis. The product has the common name “abatacept” and the brand name Orencia®. Momenta sought Inter Partes Review of the Patent under the America Invents Act, 35 U.S.C. 311. Momenta was attempting to develop a biosimilar counterpart of Orencia®. The Patent Trial and Appeal Board sustained patentability of the patent claims. Momenta filed an appeal under 35 U.S.C. 319. BMS moved to dismiss for lack of standing because Momenta’s proposed product had failed its Phase 1 clinical trials and had been withdrawn. Momenta responded that it had not abandoned its intent to produce a counterpart of the Orencia® product and filed various exhibits concerning its intentions, ultimately submitting a form that was filed with the Securities and Exchange Commission in December 2018, indicating termination of Momenta’s collaboration agreement with respect to the development of a proposed biosimilar to ORENCIA®. Momenta did not withdraw its appeal. The Federal Circuit dismissed the appeal for lack of standing as moot. The cessation of potential infringement means that Momenta no longer has the potential for injury, thereby mooting the inquiry. View "Momenta Pharmaceuticals, Inc. v. Bristol-Myers Squibb Co." on Justia Law

Athena Diagnostics is the exclusive licensee of the 820 patent, covering methods for diagnosing neurological disorders by detecting antibodies to a protein called muscle-specific tyrosine kinase (MuSK), which is associated with Myasthenia gravis (MG), a neurological disorder where patients experience muscle weakness and symptoms including drooping eyelids, double vision, and slurred speech. Athena markets a test (FMUSK) that functions by evaluating those antibodies. After Mayo developed two competing tests, Athena accused Mayo of infringing its patent. The Federal Circuit affirmed that the asserted claims of the 820 patent are invalid under 35 U.S.C. 101, for claiming ineligible subject matter. The claims at issue are directed to a natural law and lack an inventive concept. View "Athena Diagnostics, Inc. v. Mayo Collaborative Services, LLC" on Justia Law

Plaintiff filed a personal injury action against Merck after she suffered cardiovascular injuries allegedly from taking a medication called Vioxx. The Eighth Circuit reversed the district court's dismissal of plaintiff's claims. The district court held that plaintiff's claims accrued prior to September 2001 and thus her September 29, 2006 suit was time-barred. In Missouri, the statute of limitations for personal injury claims is five years after the cause of action accrues.The court held that there was a genuine issue of fact as to whether the evidence was such that a reasonably prudent person was on notice of a potentially actionable injury before September 29, 2001. The court predicted that the state supreme court would conclude that mere knowledge in the medical community of a possible link between Vioxx and heart problems did not, as a matter of law, place a reasonably prudent person in plaintiff's position on notice of a potentially actionable injury.

RCT owns the 551 patent, which discloses and claims enantiomeric compounds and pharmaceutical compositions useful in the treatment of epilepsy and other central nervous system disorders. The Patent and Trademark Office Patent Trial and Appeal Board, in an inter partes review, concluded that claims 1–13 of the patent are not unpatentable. The Federal Circuit affirmed, rejecting an argument that an ordinary artisan would have recognized the methoxyamino group in compound 3l (disclosed in a prior reference) to be uncommon and to have potential synthetic and stability problems and that a person of skill in the art would then have been motivated to modify compound 3l by replacing the amine of its methoxyamino group with a methylene link to yield a more stable, synthetically accessible, pharmaceutically common and acceptable moiety. The Board’s findings are supported by substantial evidence. Even if a person of skill in the art would have been motivated to modify compound 3l, the evidence suggests that compounds without a methoxyamino or nitrogen-containing group at the αcarbon had reduced activity.

In these consolidated appeals arising out of two “off-label” prescription drug marketing cases aggregated for pretrial proceedings in the district court by order of a multidistrict litigation panel, the First Circuit reversed the dismissal of claims brought by two of the four plaintiffs, vacated the denial of Plaintiffs’ motion to compel the production of additional documents, and otherwise affirmed the district court's rulings.In their complaint, Plaintiffs claimed that Defendants, Forest Pharmaceuticals, Inc. and Forest Laboratories, Inc., engaged in an off-label marketing scheme aimed at fraudulently inducing doctors to write pediatric prescriptions of their antidepressant drugs when the FDA had not approved the use of these medications for minors. After discovery, the district court entered summary judgment for Defendant on Plaintiffs’ Racketeer Influenced and Corrupt Organizations Act (RICO), 18 U.S.C. 1962(c)-(d), claims and dismissed Plaintiffs’ state-based allegations as deriving from their noncognizable RICO claims. The First Circuit (1) reversed the district court’s entry of summary judgment on certain plaintiffs’ RICO and state-law claims and on another plaintiff’s RICO and unjust-enrichment claims on the basis that the evidence was insufficient on these claims; (2) vacated the denial of Plaintiffs’ motion to compel; (3) affirmed the denial of class certification; and (4) otherwise affirmed.

Dr. Barry’s patents, entitled “System and Method for Aligning Vertebrae in the Amelioration of Aberrant Spinal Column Deviation Conditions,” claim methods and systems for correcting spinal column anomalies, such as those due to scoliosis, by applying force to multiple vertebrae at once. Dr. Barry sued Medtronic, alleging that Medtronic induced surgeons to infringe the patents. The jury found infringement of method claims 4 and 5 of the 358 patent and system claims 2, 3, and 4 of the 121 patent, rejected Medtronic’s several invalidity defenses, and awarded damages. In post-trial rulings on the jury issues, the district court upheld the verdict, rejecting challenges as to induced infringement and associated damages for domestic conduct, invalidity of the asserted 358 patent claims under the public-use and on-sale bars, and invalidity of all asserted claims due to another’s prior invention. The district court then rejected Medtronic’s inequitable-conduct challenge and enhanced damages by 20 percent while denying attorney’s fees to Dr. Barry, The Federal Circuit affirmed, rejecting several arguments by Medtronics, principally concerning the public-use and on-sale statutory bars, but also concerning prior invention, inequitable conduct, and induced infringement and associated damages.

Bard manufactures a surgical patch, consisting of two pieces of mesh that surround a flexible plastic ring. During a hernia repair, the patch is folded to fit through a small incision, then the plastic ring springs back into its original shape and flattens the mesh against the abdominal wall. Bard recalled several versions of the patch in 2005-2006 following reports that the plastic ring was defective. Sometimes the ring broke, exposing a sharp edge that could perforate the patient’s intestines. Other times the ring caused the patch to bend and warp, exposing the patch’s adhesive to a patient’s viscera. Before the recall, Bowersock underwent hernia repair surgery, involving a Bard patch. Roughly one year later, she died of complications arising from an abdominal-wall abscess. Her estate sued. Unlike defective patches in other injured patients, Bowersock’s patch did not adhere to her bowel or perforate her organs. Plaintiff's expert tried to present a new theory of causation: the patch had “buckled,” forming a stiff edge that rubbed against and imperceptibly perforated her internal organs. The court excluded that testimony, finding the “buckling” theory not sufficiently reliable. The Seventh Circuit affirmed summary judgment for the defense. The novel theory of causation was not peer-reviewed, professionally presented, consistent with Bowersock’s medical records or autopsy, or substantiated by other cases. View "Robinson v.
