Patent Trial and Appeal Board

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.

On August 23rd, the Federal Circuit upheld in part and reversed in part a decision from the Patent Trial and Appeal Board’s (PTAB or Board) concerning Ethicon’s patent on a robotic surgical tool, holding that the Board’s finding of no motivation to combine is not supported by substantial evidence. In doing so, the court determined the PTAB “went too far” in its holding of non-obviousness by requiring Intuitive to specifically identify a preexisting surgical device performing as many functions as required by the Ethicon patent; it was enough that the prior art established such a device was “at least possible.”

In Apple v. Qualcomm, Federal Circuit Finds No Standing to Challenge Validity of a Few Patents When Many Were Licensed

The development timeline for small-molecule drugs and biologics is lengthy, estimated to take between 10 and 15 years. As a result, pharmaceutical companies need to consider freedom to operate issues long before they receive FDA approval or market their new product. These considerations might lead a company to take a license, seek to invalidate a competitor’s patent, or some combination of the two. The Patent Trial and Appeal Board (“PTAB”) is a popular venue for challenging patent validity and in 2020, Bio/Pharma and Chemical Patents accounted for 12% of petitions filed at the PTAB.
