U.S. Federal Trade Commission releases final report on authorized generic drugs

On August 31, 2011, the United States Federal Trade Commission issued a final report on authorized generic drugs, "Authorized Generic Drugs – Short-Term Effects and Long-Term Impact." An authorized generic is a lower-cost, generic-label version of a brand-name drug that is already sold by the same manufacturer. The report examines how competition and drug prices are affected by authorized generics.

Teva's leave application to clarify scope of section 8 damages dismissed. As reported in the July 2011 edition of Rx IP Update, Teva sought leave to appeal to the Supreme Court the decision of the Federal Court of Appeal upholding the Federal Court decision to strike portions of Teva's claim. Those paragraphs sought recovery for permanent loss of market share relating to ramipril (sanofi-aventis's ALTACE). The Supreme Court dismissed Teva's leave application.

Patent Appeal Board decisions

Canadian Patent Office rejects claims to monoclonal antibodies for insufficiency and lack of sound prediction. In Genentech, Inc. Patent Application No. 2,407,304 (Re) (Commissioner's Decision #1314), the Commissioner of Patents further considered the applicant's comments after issuing her decision in #1307 in November 2010. The applicant alleged that it had not been able to fully address two issues: (i) whether the scope of claim 1 in relation to the target polypeptides is overly broad; and (ii) whether there is a sound prediction with respect to use of the claimed antibody as an anti-inflammatory agent. The Commissioner largely followed her previous decision in #1307. In particular, she found that claim 1 is overly broad for including antibodies that recognize a large class of target polypeptides, which polypeptides may bind to unknown ligands and required that the claim be limited to antibodies that cross-react with the particular target polypeptides disclosed. She also found that there is no sound prediction to support the claimed therapeutic utility as an anti-inflammatory agent.
