No Sugar-Coating: Post-AIA Patent on Secret Process Barred by Pre-Filing Sale of Product

by Dennis Crouch

Although the result could have been guessed, the Federal Circuit has issued an important decision interpreting the scope of post-AIA 35 U.S.C. 102 -- and the meaning of the "claimed invention." Celanese Intl. Corp. v. Intl. Trade Comm'n,  22-01827 (Fed. Cir. August 12, 2024).   In particular, the court affirmed the precedent of D.L. Auld -- i.e., the on-sale bar continues to block patenting of an otherwise secret process when the patentee makes pre-filing sales of product made using that process.

Com. for Intell. Prop., 579 U.S. 261 (2016) provided the patent office with Chevron deference for its determinations regarding AIA trials, including issues such as its approach to claim construction.  But Chevron has now been overruled, and many are wanting the Federal Circuit to revisit the USPTO approach.

Although I expect that the outcome

Veterans’ Benefits at the Supreme Court: The Battle Over Benefit-of-the-Doubt

by Dennis Crouch

In April 2024, the Supreme Court granted certiorari in the consolidated cases of Bufkin v. McDonough and Thornton v. McDonough, two veterans’ benefits cases on appeal from the Court of Appeals for the Federal Circuit. The cases involve the "benefit-of-the-doubt" rule, a longstanding principle that is codified in veterans law that requires the VA to resolve close or unclear issues in a veteran's favor when adjudicating benefits claims.

Both Bufkin and Thornton are veterans who were denied disability benefits by the VA.
