Double Trouble: IPO asks for Supreme Court review of PTA/ODP Cellect dispute

by Dennis Crouch

A second amicus brief has been filed - this one from the Intellectual Property Owners Association (IPO) - encouraging the Supreme Court to grant certiorari in Cellect, LLC v. Vidal, No. 23-1231. The case concerns the interplay between the Patent Term Adjustment (PTA) statute, 35 U.S.C. § 154(b), and the judicially-created doctrine of obviousness-type double patenting (ODP).

The NYIPLA Brief: Advocating for Patent Term Adjustments

by Dennis Crouch

The Federal Circuit's 2023 decision in In re Cellect, LLC, 81 F.4th 1216 (Fed. Cir. 2023) has set the stage for a potentially significant Supreme Court case on the interplay between the Patent Term Adjustment (PTA) statute, 35 U.S.C. § 154(b), and the judicially-created doctrine of obviousness-type double patenting (ODP). Cellect is now seeking certiorari, and the New York Intellectual Property Law Association (NYIPLA) has stepped in with an amicus brief supporting the petition, arguing that the case presents "questions of exceptional importance." Brief for New York Intellectual Property Law Association as Amicus Curiae Supporting Petitioner at 23, Cellect, LLC v. Vidal, No. 23-1231 (U.S. May 28, 2024).

Cellect or Reject? SCOTUS Asked to Consider Fate of ODP Doctrine

by Dennis Crouch

In its new petition for certiorari in Cellect LLC v. Vidal, No. __ (U.S. May 20, 2024), Cellect argues that the Federal Circuit erred in upholding the PTAB's (PTAB) invalidation of Cellect's four patents based on the judicially-created doctrine of obviousness-type double patenting (ODP). The key issue is whether ODP can cut short the patent term extension provided by the Patent Term Adjustment (PTA) statute, 35 U.S.C. § 154(b). Meanwhile, Dir. Vidal is looking to extend the power of ODP via rulemaking. This is an important case coming at an important time.

Patent Term Adjustment and Obviousness-Type Double Patenting: Cellect’s Bid for Supreme Court Review

by Dennis Crouch

The Federal Circuit's August 2023 decision in In re Cellect, LLC has set-up a significant question regarding the interplay between the patent term adjustment (PTA) statute, 35 U.S.C. § 154(b), and the judicially-created doctrine of obviousness-type double patenting (OTDP). Now, Cellect is seeking Supreme Court review, recently filing a petition for an extension of time that also indicated its intent to file. Cellect's petition is now due May 20, 2024, and I expect significant support from the patent owner community.

Patentees often receive PTA due to USPTO delays that otherwise eat into the 20-year patent term.  A fundamental issue in Cellect boils down to whether a patentee must forfeit their PTA term extensions to avoid an OTDP invalidity finding.  This comes up in situations where a patentee has two patents that cover only slightly different inventions.  Most often this is seen in family-member continuation applications, but it can also arise when applicants file several applications all within a short period.
