Dr. David Jang, M.D., is the named inventor of the patent, which is directed to a coronary stent. Jang assigned the patent to BSC. BSC agreed to pay a royalty if it ever produced a product that would infringe the patent. Jang sued, based on BSC’s “Express stent.” BSC sought ex parte reexamination, then sought to include invalidity defenses in Jang’s suit. The district court denied the motion, deeming invalidity defenses “irrelevant” as to whether BSC owed royalties for past sales. The Patent and Trademark Office subsequently cancelled the asserted claims as unpatentable. The court denied BSC’s motion in limine to preclude Jang from presenting a doctrine of equivalents theory, finding that Jang’s experts sufficiently explained his doctrine of equivalents theory in their expert reports. The jury ultimately found no literal infringement, but found infringement under the doctrine of equivalents. Following through on its earlier decision, the district court conducted an evidentiary hearing on ensnarement. Concluding that Jang did not meet his burden of persuasion, which includes providing a proper hypothetical claim that does not ensnare the prior art, the district court vacated the jury verdict and entered judgment of non-infringement. The Federal Circuit affirmed the entry of judgment of non-infringement. View "Jang v. Boston Scientific Corp." on Justia Law

The Biologics Price Competition and Innovation Act, 42 U.S.C. 262, establishes a scheme for adjudicating claims of patent infringement in the FDA's approval of “biological products.” To obtain FDA approval, the sponsor of a new biological product must demonstrate that it is “safe, pure, and potent.” For a “biosimilar” product based on an approved “reference” product, a party may submit an abbreviated “subsection (k)” application that “piggybacks” on the showing made for an approved reference product but must provide the reference product's sponsor with its subsection (k) application and information that describes the manufacturing process. The parties then collaborate to identify patents for immediate litigation. The second phase is triggered by the applicant’s notice of commercial marketing and involves any patents that were included on the lists but not previously litigated. Hospira's subsection (k) application sought approval of a biosimilar of EPOGEN®, Amgen’s FDA-approved product, Although Amgen asserted that Hospira failed to disclose the composition of the cell-culture medium used during manufacturing, the parties began identifying patents. Amgen claimed that it could not assess the reasonableness of asserting infringement claims concerning other patents for culturing cells and moved to compel discovery on the composition of Hospira’s cell-culture medium in its suit on listed patents. The court denied Amgen’s motion, stating that the information had no relevance to the asserted patents. Amgen appealed that interlocutory order. The Federal Circuit dismissed, holding that it lacked jurisdiction under the collateral order doctrine and that Amgen failed to satisfy the prerequisites for mandamus. View "Amgen, Inc.. v.

The specifications of the three Soft Gel patents describe a method for dissolving CoQ10. The patented inventions include a composition, a soft gelatin capsule, and a method of making such a soft gelatin capsule, each involving a solution of CoQ10 dissolved in a monoterpene. CoQ10, also called ubiquinone, is a coenzyme, i.e., a chemical compound that is required for the biological activity of certain proteins and is necessary for certain metabolic processes and for the production of cellular energy; it has a secondary role as an antioxidant. In clinical trials, CoQ10 has been shown to be effective in regulating blood pressure and cholesterol levels, improving cardiovascular health, and “thwarting various diseases such as certain types of cancers.” It is “sparingly soluble in hydrophilic solvents such as water.” According to the patents, at the time of the inventions, most solvents that were used to administer CoQ10 in liquid form could dissolve, at most, only about 5 to 10 percent of the CoQ10. Jarrow requested inter partes reexaminations of the three Soft Gel patents. The Patent Board invalidated several claims. The Federal Circuit affirmed, finding the claims invalid as obvious in light of prior references, 35 U.S.C. 103(a). View "Soft Gel Technologies, Inc. v. Jarrow Formulas, Inc." on Justia Law

Millennium developed the patented product for the treatment of oncology diseases, particularly multiple myeloma and mantle cell lymphoma. The product has the brand name Velcade®. Sandoz and others filed abbreviated new drug applications (ANDAs), admitting infringement and seeking to invalidate various claims of the 446 Patent. The district courts held that certain claims were invalid as obvious, 35 U.S.C. 103. In consolidated appeals, the Federal Circuit concluded that the district court erred and that invalidity was not established. Sandoz identified no reference or combination of references that show or suggest a reason to make the claimed compound. The district court clearly erred in its examination of the objective indicia of unexpected results and long-felt need. View "Millenium Pharmaceuticals, Inc. v. Sandoz, Inc." on Justia Law

The claims at issue involve testing methods for fetal aneuploidies, conditions in which a fetus either has an abnormally high number of chromosomes (e.g., Down’s syndrome) or an abnormally low number (e.g., Turner’s syndrome). Previously, physicians diagnosed fetal aneuploidies using invasive amniocentesis or chorionic villus sampling or less invasive methods, such as ultrasonography and biochemical marker detection that had suboptimal accuracy. In three interference proceedings between Stanford and Chinese University, the Patent Trial and Appeal Board found that Stanford’s claims were unpatentable for lack of written description. The Federal Circuit vacated, finding that the Board relied on improper evidence and did not cite other substantial evidence to support its key findings. Whether a patent claim satisfies the written description requirement, 35 U.S.C. 112, depends on whether the description clearly allows persons of ordinary skill in the art to recognize that the inventor invented what is claimed. On remand, the Board should examine whether a person of ordinary skill would have understood that the patent’s specification disclosed random MPS sequencing and would have known, as of the priority date, that the specification’s reference to Illumina products meant random MPS sequencing as recited in the claims, by examining the record evidence as to pre-filing date art-related facts on Illumina products.

When an artery is damaged or inflamed, the body releases the enzyme myeloperoxidase (MPO). Prior art taught that MPO could be detected in an atherosclerotic plaque or lesion that required a surgically invasive method; could be indirectly detected in blood; or could be detected in blood with results that were not predictive of cardiovascular disease. Cleveland Clinic purportedly discovered how to “see” MPO in blood and correlate that to the risk of cardiovascular disease. True Health, a diagnostic laboratory, purchased the assets of Diagnostics, which had contracted with Cleveland Clinic to perform MPO testing. Rather than continue that relationship, True Health performed its own MPO testing. Cleveland Clinic sued, asserting infringement of the patents. The district court found all the claims patent-ineligible under 35 U.S.C. 101; dismissed the contributory and induced infringement claims of the 260 patent; denied leave to amend; and held that it was proper to consider section 101 at the motion to dismiss stage.. The court found that the claims were directed to a law of nature, with no saving inventive concept. The Federal Circuit affirmed. Cleveland Clinic provided no proposed construction of any terms or proposed expert testimony that would change the analysis. The claims, whether considered limitation-by-limitation or as a whole, do not sufficiently transform the natural existence of MPO in a bodily sample and its correlation to cardiovascular risk into a patentable invention.
