Federal Circuit: Pfizer v. Lee

Patent, Procedure

Claim not waived, as it was referenced in briefs and at argument below.

The time that should have been added to the end of the patent was appropriately tolled during the interval between the notice of insufficiency and the revised notice of insufficiency, as the initial notice put the petitioner on notice of the shortcomings in the claim.

Dissent: A response to an incomplete notice might have itself been incomplete.
