Federal Circuit Changes Standard for Covered Business Method Review

The Federal Circuit found that the Patent Trial and Appeal Board (PTAB) used an overly broad definition of financial activity in conducting a Covered Business Method Review in Secure Access v.

Cir. 2016), i.e., 'a specific improvement—a particular database technique—in how computers could carry out one of their basic functions of storage and retrieval of data,' regardless of subject matter or the use to which that functionality might be put, Elec. Power, 830 F.3d at 1354 (describing Enfish). Here, the claims are directed to selecting and sorting information by user interest or subject matter, a longstanding activity of libraries and other human enterprises."
