On August 13, the Federal Circuit issued a precedential ruling in Allergan USA Inc. et al. v. MSN Laboratories Private Ltd. et al., Case Number 24-1061, U.S. Court of Appeals for the Federal Circuit.
Federal Circuit Decision Clarifies Obviousness-Type Double Patenting and Patent Term Adjustments In Allergan v. MSN Laboratories
On August 13, the Federal Circuit issued a precedential ruling that reversed the District of Delaware's application of the Federal Circuit precedent in In re: Cellect to invalidate a claim in an earlier-filed parent application over admittedly patentably indistinct claims in later-filed (and earlier-expired) child patents. This decision has resolved some substantial questions about the application of obviousness-type double patenting that had been raised by last year's In re Cellect decision.
