OSI Pharmaceuticals Decision Has Limited Use in Supporting Patentability of Method of Treatment Claims

Earlier this month, Mallinckrodt succeeded in its inter partes review (IPR) challenge against patent owner Biovie, Inc. (Biovie). The Patent Trial and Appeal Board’s (PTAB’s) final determination held that all claims of Biovie’s U.S. Patent No. 9,655,945 (the ‘945 patent) were unpatentable. The claims of Biovie’s ‘945 patent, directed to administering terlipressin to ascites (abnormal buildup of fluid in the abdomen) patients, were deemed anticipated and/or obvious over the prior art. During the IPR, Biovie attempted to use the recent Federal Circuit decision from OSI Pharmaceuticals v. Apotex (OSI) as a shield to patentability, but the shield was unsuccessful. As such, OSI is unlikely to be a cure-all for pharmaceutical method of treatment claims, in IPR proceedings or otherwise.

What Petitioners and Patent Owners Need to Know About the Scope of IPR Estoppel

In the recent case of Intellectual Ventures v. Toshiba, Judge Robinson noted that “the Federal Circuit has construed the language quite literally” in the use of the word “during.” The term is spelled out as “any ground that the petitioner raised or reasonable could have raised during that inter partes review” in § 315(e)(1). The judge noted that while extending the logic of non-instituted grounds as not being able to be raised “during” an IPR proceeding to prior art references that were never presented to the Patent Trial and Appeal Board at all “confounds the very nature of this parallel administrative proceeding, the court cannot divine a way around the Federal Circuit’s interpretation in Shaw.” Thus, she did not estop Toshiba from presenting the grounds never presented to the PTAB in a pair of orders in December and January, and heavily implied that the Federal Circuit should weigh in to clarify the issue.

Biologics Applicant Must Give Post-Approval Notice to Reference Product Sponsor

The Federal Circuit held that there was no statutory language that made section (8)(A) non-mandatory. Further, Amgen v. Sandoz disposed of Apotex’s argument that (8)(A) would extend the 12-year exclusivity period given to a sponsor by 180 days (six additional months). Even when market entry is delayed under (8)(A) by 12 years plus 180 days, the result is the same, because the 12-year date is established as the earliest date, not the latest date, on which a biosimilar license can take effect. The Court affirmed that section (8)(A) covers applicants that filed (2)(A) notices as well as those that did not. This is to ensure that the necessary decision-making regarding further patent litigation starts from when the applicant’s product, uses, and processes are fixed by the FDA license. The 180-day period gives the sponsor essential time to assess its infringement position for the final FDA approved product and the as to yet-to-be-litigated patents. This is confirmed by the legislative history of the Biologics Act. Thus, an applicant must provide a reference product sponsor with the 180-day notice under 8(A), after approval and before commercial marketing begins, whether or not the applicant previously provided a (2)(A) notice of the FDA review.

Valid but Not Infringed, Merck’s Loses Blockbuster Nasonex®

Last week, on Friday, June 15, 2012, Merck (NYSE: MRK) announced the U.S. District Court for the District of New Jersey (Judge Peter G. Sheridan) ruled against the company on the issue of patent infringement in its suit against Apotex Inc. According to Merck, global sales of Nasonex® in 2010 topped $1.2 billion. See Merck News. A variety of Internet sources place the Nasonex® market share of the inhaled steroid market at 47%. Therefore, this patent loss some 6 years before the Nasonex® patent expires is a big deal.
