Federal Circuit Finds Wyeth Restenosis Claims Invalid As Not Enabled

Posted in Enablement; Federal Circuit Decisions

In Wyeth v. Abbott Laboratories, the Federal Circuit affirmed the district court’s decision that the claims at issue are invalid for failing to satisfy the enablement requirement of 35 USC § 112. The court took only 10 pages to explain why a specification that describes one specific compound did not enable claims encompassing tens of thousands of compounds.

District Court Denies Equitable Tolling, Fifth Amendment Taking In Novartis Patent Term Adjustment Case

Posted in District Court Decisions

In another significant Patent Term Adjustment (PTA) case decided last week (Novartis AG v. Kappos, Civ. Action No. 10-cv-1138 (Nov. 15, 2012)), the U.S. District Court for the District of Columbia found that Novartis could benefit from “ordinary tolling” but not “equitable tolling” in its efforts to obtain additional PTA for 23 patents.

An Appealing Patent Term Adjustment Issue

Posted in Patent Office Practice; Patent Term Adjustment

Since the Federal Circuit decision in Wyeth v. Kappos, we have been applying greater scrutiny to the USPTO’s interpretations of the Patent Term Adjustment (PTA) statute. While we previously reviewed the USPTO’s calculations to ensure that the USPTO delays and Applicant delays were correctly counted in accordance with the rules, we find ourselves more frequently questioning whether the rules themselves are in accord with the statute. Just like the Federal Circuit determined that the USPTO’s interpretation of 35 USC § 154(b)(2)(A) was inconsistent with the statute, I think that the USPTO’s interpretation of 35 USC § 154(b)(1)(B)(ii) improperly excludes time that has nothing to do with an actual appeal to the Board.
