Review of 2015 Trends in Fluid Catalytic Cracking Patents, Part I: Catalyst Additives

This is the first article in a review of patents issued in 2015 in the area of Fluid Catalytic Cracking (FCC). The summary below covers five patents relating to FCC catalyst additives. These include: two related to gasoline sulfur reduction catalysts; two related to metals deactivators/traps; and a ZSM-5 additive patent. Review of this collection of patents illustrates a somewhat subdued activity in additive research activity for the FCC, at least that devoted to patentable activities. To be fair, there are almost double the number of “catalyst” related patents, and some of these are directed to olefin production, which would boost the number in the olefin/octane area. These will be summarized next month. For the sulfur reduction and metals trapping areas, time will tell whether there is a resurgence in these areas.

Will Biosimilar Manufacturers Have to Wait? Sandoz Petitions Supreme Court for an Answer

Last week, Sandoz, the generic pharmaceuticals division of Novartis, petitioned the Supreme Court to review a Federal Circuit decision concerning a case involving Zarxio, its biosimilar version of Amgen’s Neupogen. At issue is the court’s interpretation of the Biologics Price Competition and Innovation Act (BPCIA). The BPCIA establishes an alternative pathway for FDA approval of biosimilars and patent-dispute resolution, allowing litigation prior to FDA approval and marketing of biosimilars.

The Emergent Microbiome: A Revolution for the Life Sciences – Part V, Patents Relating to Obesity and Metabolic Disorders

This is the fifth installment in a series on advancements in microbiome research and development. This article will summarize issued U.S. microbiome-based patents that describe therapies relating to obesity and other metabolic disorders. It is a follow-up to the fourth part of the series, which reviewed important research and development in this subject area. The patents reviewed herein are neatly summarized in the table at the end of this installment.

The diet and nutrition industry is big business: the industry brings in over $60 billion dollars from the nation’s 100 million-plus dieters. Yet, years of R&D have failed to produce a blockbuster weight loss drug. Clearly, there is a big incentive to develop new and effective therapies for this area, particularly considering the risks and adverse events that have plagued previous prescription therapies, and companies are looking to the untapped potential of the microbiome for an elusive wonder drug.

The Emergent Microbiome: A Revolution for the Life Sciences – Part IV, Obesity and other Metabolic Disorders

Some of the earliest evidence for the relationship between the microbiome and obesity came from studies of antibiotics and their association with weight gain in livestock, which pointed to a link between microbiome composition and weight maintenance. A 2006 study from the laboratory of the prominent researcher Jeffrey Gordon uncovered a mechanism by which some gut bacteria trigger obesity. Lead author Peter Turnbaugh and his colleagues noted that obese mice had different microbiomes than their lean littermates. The same was true of lean and obese human twins. When Gordon’s team characterized this phenomenon, they found that the microbiomes in obese mice and humans obtain more calories from food as compared to the microbiomes of their lean counterparts. In addition, when the researchers transferred the gut bacteria of an obese mouse to a germ free one, the formerly germ free mouse became obese.

Upcoming Free Webinar on Patent and Regulatory Issues for Pharmaceuticals

Dr. Anthony Sabatelli, head of Dilworth IP’s Pharmaceutical and Biotech Patent Practice, will be hosting the second of this year’s Dilworth IP Webinar Seminars. This session, entitled At the Intersection of Patent and Regulatory Law – Navigating the Challenges for Pharmaceuticals, will address the special challenges pharmaceutical products present for companies and their multidisciplinary teams. These challenges exist because pharmaceuticals, unlike most other chemical products, sit at the intersection of patent and regulatory law. In this webinar, Dr. Sabatelli will provide a basic introduction to the applicable patent and regulatory laws, focusing on their interplay over the product life cycle of a pharmaceutical product, from its inception in the lab, through R&D, human clinical testing, marketing, and eventual generic competition. Concepts such as patent term extension (35 USC 156), and the regulatory and market exclusivity periods granted upon approval of a NDA (21 USC 355) will be discussed. An example of a timeline for a pharmaceutical product will be presented to illustrate the fascinating interplay of these concepts and their importance for those multidisciplinary teams needing to make high stakes business decisions.

Dilworth IP’s Dr. Schuchardt Featured in the IP Litigator

Dilworth IP’s Dr. Jonathan Schuchardt has recently had an article published in the bi-monthly publication IP Litigator. His article, entitled “The Federal Circuit Sees Nova’s Light,” considers the effects of the Supreme Court’s decision in Nautilus Inc. v. Biosig Instruments, Inc. on the issue of “indefiniteness,” especially with regard to previous cases involving patents filed by Dow Chemical.
