Double Patenting and Patent Term Adjustment

Patent, , ,

by Dennis Crouch

The Federal Circuit recently issued an important decision in In re: Cellect, LLC (Fed. Cir. Aug. 28, 2023) regarding how Patent Term Adjustment (PTA) interacts with terminal disclaimers and obviousness-type double patenting (ODP). This case establishes binding precedent that a terminal disclaimer cuts off any extended patent term granted through PTA.

This holding contrasts with the court's prior rulings regarding Patent Term Extension (PTE), where the extended term is calculated from the disclaimed expiration date, not the original expiration date. Thus, PTE extends beyond a disclaimed term, while PTA does not.

This result was expected by many patent experts, although some in the pharmaceutical industry had pushed for PTA to extend beyond disclaimed terms similarly to PTE. In the end, the statutory language expressly addressing disclaimers in the context of PTA proved decisive. This precedent will apply to all patents already in-force as well as those issued in the future.  Thus, applicants will want to carefully consider PTA and terminal disclaimer strategy for patent families.

Patent, ,

Feb 1, 2023, is the new deadline for providing comments to the USPTO on this RFC.

Topics: The USPTO invites written responses to the following questions and requests. Commenters are welcome to respond to any or all of the questions.

1. Identify any specific sources of prior art not currently available through the Patents End-to-End Search system that you believe examiners should be searching. How should the USPTO facilitate an applicant's submission of prior art that is not accessible in the Patents End-to-End Search system ( e.g., “on sale” or prior public use)?

2. How, if at all, should the USPTO change claim support and/or continuation practice to achieve the aims of fostering innovation, competition, and access to information through robust and reliable patents? Specifically, should the USPTO:
