CAFC Vacates PTAB Obviousness Decision, Nonobviousness Nexus Established by Patent Owner

The Federal Circuit recently issued a non-precedential decision in LiquidPower Specialty Products v. Baker Hughes, vacating and remanding a final written decision from the Patent Trial and Appeal Board (PTAB), which had invalidated claims of a LiquidPower patent in an inter partes review (IPR) proceeding. In a nutshell, the Federal Circuit found there to be substantial evidence supporting PTAB determinations relating to specifically what the prior art taught, and what the prior art motivated those of skill in the art to do vis-a-vis motivation to combine. However, the panel, made up of Chief Judge Sharon Prost and Circuit Judges Todd Hughes and Kimberly Moore, determined that substantial evidence did not support the PTAB’s finding that the patent owner failed to establish a nexus between the claimed invention and objective evidence of nonobviousness, or secondary considerations as they are sometimes called. The case is now remanded to the PTAB for proper consideration of the objective evidence of nonobviousness presented by the patent owner.

Expansion of the Blocking Patent Doctrine: Trading Logic for Gremlins

Since Merck & Co. v. Teva Pharmaceuticals, blocking patent arguments have arisen in the Federal Circuit primarily in the pharmaceutical patent context, and until now have largely been limited to undermining evidence of commercial success. But just like gremlins fed after midnight, this doctrine inevitably spawned unwanted offspring that are now wreaking havoc… Assuming that no one would ever develop a product that might infringe a patent is inconsistent with numerous Federal Circuit realities. It’s right up there with the Tooth Fairy (sorry, kids).
