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The Federal Circuit recently issued a non-precedential decision in LiquidPower Specialty Products v. Baker Hughes, vacating and remanding a final written decision from the Patent Trial and Appeal Board (PTAB),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. 

Best Mode Patent-Raptor Claims Another Victim in Wellman

What is startling about Wellman is how the patentee put the ‘863 and ‘317 patents squarely in the path of the “best mode” Patent-Raptor by deliberately keeping the Ti818 recipe a trade secret. As I’ve instructed numerous clients, you have a clear choice on “best mode” issue: (1) disclose the “best mode” and file the patent; or (2) don’t file the patent if you want to keep the “best mode” as a trade secret. There is simply no “in between” on this issue. The only question now is whether the Tyrannosaurus Rex of patent law (inequitable conduct) will devour what is left of the Wellman patents.
