In a recent turn of events, patent owners have filed an amicus brief in support of Cellect’s rehearing petition. This move comes on the heels of a significant U.S. Court of Appeals decision, with substantial implications on obvious-type double patenting (“ODP”).
The precedential decision in question, arising from In re Cellect, ruled that when expiration dates of patents within a family differ solely due to patent term adjustment (“PTA”), earlier-expiring family patents may serve as the basis for an obvious-type double patenting attack on the later-expiring family patents. JD Supra relayed this information to the public.
The filing of the amicus brief intriguingly reveals the community of patent owners lining up to champion Cellect’s petition for rehearing. Given the use of the earlier family members in a ODP attack on the later expiring patents, this could potentially redefine the landscape of patent protection, particularly where patent families are concerned.
Though the future fate of Cellect’s rehearing petition remains a topic of conjecture, the considered perspective of patent owners brings a compelling dimension to the dialogue surrounding fair implementation of the ODP doctrine. Even as we watch this space for unfolding developments, the scenario offers an immersive lens into the dynamic world of patent law and policy.
