Federal Circuit Reverses US$200M+ Jury Verdicts Because Asserted Claims Are Unpatentable Under § 101

According to 35 U.S.C. § 101, “any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof” may be patentable. Courts and litigants often struggle in determining what falls outside this scope—i.e., what is unpatentable subject matter. The Federal Circuit Court of Appeals dealt with this issue in a series of appeals between USAA v. PNC Bank (CAFC Nos. 2023-1639, 2023-1778, 2023-1866, 2025-1276, 2025-1277, and 2025-1341), held that the claims in the patents at issue recite unpatentable subject matter, and reversed the entries of judgment for the US$218M and US$4.3M jury verdicts that issued out of the Eastern District of Texas.

What Is the Patent Trial and Appeal Board?

The Patent Trial and Appeal Board (PTAB) is a tribunal within U.S. Patent and Trademark Office. The PTAB oversees trial proceedings, namely: inter partes review (IPR), post-grant review (PGR), covered business method (CBM) review, and derivation proceedings. The Board also hears appeals from adverse patentability decisions by patent examiners in original applications, reissues, and reexaminations. And, while phasing out since the passage of the America Invents Act (AIA) in 2011, the PTAB is also responsible for deciding interferences. The PTAB was previously referred to as the Board of Patent Appeals and Interferences and was renamed by the AIA....Read more
