AstraZeneca, a manufacturer of pharmaceutical products, appealed from the district court's grant of summary judgment. AstraZeneca sought declaratory judgment that the FDA could not approve generic versions of its Seroquel product and sought to restrain the FDA from approving abbreviated new drug applications (ANDAs) for such competing products until the expiration of a period of exclusivity. As a preliminary matter, the court determined that its decision would affect AstraZeneca's actual rights and the case was not moot. On the merits, the court concluded that AstraZeneca's claims failed because the Federal Food, Drug, and Cosmetic Act (FDCA), 21 U.S.C. 301-99, only provided exclusivity for changes approved as part of a supplement. Because the FDA reasonably considered Table 2, a table summarizing previously submitted glucose data, as separate from the pediatric supplements, Table 2 was not a change approved in the supplement and therefore the statute did not entitle AstraZeneca to exclusivity for Table 2. Accordingly, the court affirmed the judgment. View "AstraZeneca Pharmaceuticals LP v. FDA, et al" on Justia Law

The 753 patent is directed to a heart rate monitor that purports to improve upon the prior art by effectively eliminating noise signals during the process of detecting a user’s heart rate. According to the patent, prior art monitors did not eliminate signals given off by skeletal muscles (EMG signals), which are brought about when users move their arms or squeeze the monitor with their fingers. Biosig, the assignee of the 753 patent, brought a patent infringement action against Nautilus. After claim construction of the disputed term ”space relationship,” the district court declared the patent invalid. The Federal Circuit reversed and remanded, finding the claims at issue not invalid for indefiniteness. View "Biosig Instruments, Inc. v. Nautilus, Inc." on Justia Law

In the mid-1990s, Biogen scientists discovered that patients with Chronic Lymphocytic Leukemia could be treated using anti-CD20 antibodies like Biogen’s Rituxan. Biogen obtained the 612 patent covering a method for treating patients with CLL involving administering a therapeutically effective amount of the anti-CD20 antibody, entitled “Treatment of Hematologic Malignancies Associated with Circulating Tumor Cells Using Chimeric Anti-CD20 Antibody.” The patent was not limited to any particular type of antiCD20 antibody. In 2002, GSK and Genmab developed a breakthrough anti-CD20 antibody, Arzerra, which is distinctly different from Rituxan in several respects. Unlike Rituxan, which is a chimeric antibody, Arzerra is a fully human antibody, with less risk that the body will reject it and it can bind longer, giving the antibody more time to kill the target B cell. In 2010, Biogen sued GSK for infringement. The district court applied a construction of “anti-CD20 antibody” that narrowed the term based on prosecution history disclaimer. Under that construction, Biogen stipulated that it could not prove infringement and appealed the claim construction. The Federal Circuit affirmed; the district court did not err in finding a clear and unmistakable disclaimer. View "Biogen Idec, Inc. v. GlaxoSmithKline, LLC" on Justia Law

First introduced in 1960, combined oral contraceptive (COC) “birth control pills,” deliver synthetic hormones that regulate the natural ovarian cycle and prevent pregnancy. Bayer filed an application directed to a low-dose, extended-regimen COC in 1993, which eventually led to the 564 patent. Bayer received final approval to market YAZ in the U.S. in 2006. Defendants filed Abbreviated New Drug Applications with the U.S. Food and Drug Administration seeking approval to market generic versions of YAZ, with certifications asserting that the 564 patent is invalid (21 U.S.C. 355(j)(2)(A)(vii)(IV). Bayer responded with patent infringement actions. The district court entered summary judgment that the patent’s claims are not invalid for obviousness in view of numerous cited prior art references. The Federal Circuit reversed, finding that Bayer did not present evidence that overcomes the plain disclosures and express motivation to combine those disclosures in the prior art.

Saffran is the owner and sole named inventor of the 760 patent, entitled “Method and Apparatus for Managing Macromolecular Distribution,” which concerns “treatment of injured tissues within human or animal bodies, specifically ... the way injured tissues are joined and the way macromolecules are directed to promote healing.” The patent discloses methods and devices for treating injured tissues by sequestering particles and macromolecules in a defined space using a selectively permeable barrier. The specification primarily describes the invention in terms of a strategy for treating serious bone fractures, known as complex or comminuted fractures, where the bone has been shattered into numerous fragments. The district court held Cordis liable for infringing multiple claims of the patent. The Federal Circuit reversed, holding that the district court erroneously construed the “device” and “release means” limitations of the asserted claims. View "Saffran v. Johnson & Johnson" on Justia Law

Plaintiff and others sought and received LASIK eye surgery with a Nidek EC-5000 Excimer Laser System ("Laser") to correct farsightedness. Plaintiff, on behalf of himself and a class of similarly situated individuals, claimed that, had they known that the FDA had not approved the Laser for this use, they would not have consented to the surgeries. The court held that the complaint did not state a claim under the California Protection of Human Subjects in Medical Experimentation Act, Cal. Health & Saf. Code 24171 et seq., because the surgeries were not "medical experiments" subject to the protection of the Act. Plaintiff did not have standing to sue for injunctive relief under the California Consumers Legal Remedies Act (CLRA), Cal. Civ. Code 1750 et seq., and his other substantive claim was preempted by the Federal Food, Drug, and Cosmetic Act (FDCA), 21 U.S.C. 301 et seq. Plaintiff's common-law fraud by omission claim was expressly preempted by the preemption provision in the Medical Device Amendments. Even if it were not, it was impliedly preempted because it amounted to an attempt to privately enforce the FDCA. Accordingly, the court affirmed the dismissal of the complaint. View "Perez, et al v. Nidek Co., Ltd., et al" on Justia Law

1999, Drs. Dawson and Bowman submitted the patent application that led to the issuance of the two patents at issue, which concern a method for topically treating and preventing infections of the eye. They claim to overcome difficulties in existing methods through a process for topically applying an azalide antibiotic to the eye. Both patents are entitled “Topical Treatment or Prevention of Ocular Infections.” In 2007, in order to provoke an interference, UCSF filed a patent application that named Dr. Dawson as the sole inventor and generally copied the specification and claims from the patents. Dr. Dawson declined to join UCSF’s submission. The Patent and Trademark Office’s Board of Patent Appeals and Interferences found that Dr. Dawson did not conceive of the claimed inventions by himself prior to his collaboration with Dr. Bowman. The Federal Circuit affirmed, noting that, apart from reduction to practice, conception requires that the inventor know how his “definite and permanent idea of the complete and operative invention ... is hereafter to be applied in practice.” View "Dawson v. Dawson & Bowman" on Justia Law

This case stemmed from Cytori's application to the FDA to market two new medical devices, the Celution 700 and the StemSource 900. Two devices that use adipose tissue as a source of stem cells that could later be used in lab analysis or, potentially, in regenerative medicine. The FDA concluded that the Celution and the StemSource were not substantially similar to devices on the market that extract stem cells from blood or bone marrow. Thus, the FDA ruled that Cytori must go through an extensive premarket approval process for new medical devices, rather than go through the streamlined premarket notification process for new devices that would be substantially equivalent to another device already on the market. Cytori appealed. As a preliminary matter, the court concluded that it was the proper forum for direct review of the FDA's substantial equivalence determination. On the merits, the court concluded that the FDA reasonably concluded and reasonably explained, for purposes of the Administrative Procedures Act, 5 U.S.C. 500 et seq., that the Celution and StemSource did not meet either the "intended use" requirement or the "technological characteristics" requirement for a substantial equivalence determination.

This case involved a confidential document called the Project Tulip Financial Analysis (Tulip FA), which projected profits, as well as discussed the appropriate terms and benefits from a settlement, involving Solvay's highly lucrative patent on AndroGel, a topical testosterone gel. Solvay subsequently appealed the district court's decision to modify an earlier protective order and unseal the Tulip FA. The court affirmed the district court's judgment, concluding that the district court did not abuse its considerable discretion to modify its own protective order. The district court found that the passage of time had altered the balance enough so that the value of public access to the Tulip FA exceeded the value of confidentiality to Solvay. The court also vacated the stay entered by a panel of the court. View "Federal Trade Commission v. AbbVie Products LLC" on Justia Law

Fulgenzi was prescribed the generic drug metoclopramide (FDA approved in 1980), sold originally under the brand name Reglan, a drug approved for short-term treatment of patients suffering from gastroesophageal reflux disease. In her suit, claiming failure to adequately warn of risks, she alleged that taking the drug caused her to develop tardive dyskinesia, an often-irreversible neurological disorder that causes involuntary movements, especially of the lower face. In 2009, the Supreme Court held that with respect to branded drug manufacturers, state failure-to-warn suits were not preempted by the federal Food Drug and Cosmetic Act , 21 U.S.C. 301. In 2011 the Court held that such suits could not go forward against generic drug manufacturers, as it is impossible to comply simultaneously with their state duty to adequately warn and their federal duty of sameness (federal law requires generic drug labels to be the same as their branded counterpart). The district court dismissed. The Sixth Circuit reversed, noting that after the branded-drug manufacturer of metoclopramide strengthened warnings on its label, the generic manufacturer failed to update its label as required by federal law, rendering compliance with both federal and state duties no longer impossible.
