In Univ. of Strathclyde v. Clear-Vu Lighting LLC, the Federal Circuit grappled with the issue of whether claims directed to methods and systems for inactivating bacteria using blue light were obvious in view of a prior art combination that taught the claimed elements but lacked an indication of success. Ultimately, the Federal Circuit found that the patent’s success where the prior art failed – inactivation of the bacteria without a photosensitizer did not support a finding of obviousness.

The Federal Circuit’s recent ruling in MaxPower Semiconductor Inc. et al v. Rohm Semiconductor USA, LLC highlights the interplay between the liberal federal policy favoring arbitration agreements and the Patent Trial and Appeal Board’s (“PTAB”) authority as an agency tribunal having a broad role to protect the public interest in ensuring the quality of patents.

Challenging the validity of a patent through the inter partes review (IPR) process at the PTAB is a conventional alternative to litigating invalidity in federal court. MaxPower addressed the question of whether the PTAB will defer to an agreement to arbitrate that did not expressly preclude the parties from proceeding before the PTAB.
