Is the United States’ Nonobviousness Test ‘Plausibly’ Similar to the EPO/UK Inventive Step Standard?

Recent cases in the European Patent Office (EPO), the UK, and United States illustrate substantive differences between these jurisdictions as they continue to develop their inventive step/nonobviousness frameworks. In particular, the EPO and UK have recently provided guidance on a concept known as “plausibility,” i.e., whether the scope of the patent must be justified by the patentee’s technical contribution to the art in solving an identified problem. “If it is not plausible that the invention solves any technical problem then the patentee has made no technical contribution and the invention does not involve an inventive step.” Sandoz Limited v. Bristol-Meyers Squibb Holdings [2023] EWCA Civ 472. That standard, however, is quite dissimilar from the United States’ statutory standard of whether “the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious…”

The Inventive Step in Chinese Patent Law Compared With the U.S. Non-Obviousness Standard

While China is becoming an increasingly attractive patent filing destination for foreign companies, foreign counsels are often confused by the country’s inventive step requirement. Indeed, Chinese patent examiners often use abstract legal terms, such as “prominent substantive features” and “notable progress,” in their inventive step analysis. This article provides an overview of the inventive step requirement in China, in comparison with the non-obviousness standard in the United States.

The quest for patent quality: European inventive step and US obviousness

In Europe and the US, patentability depends on a showing of inventiveness that is based on similar legal requirements but practice differs substantially and the resulting patent quality varies… At the USPTO, patent applications are rejected for obviousness (35 USC §103) already in a first Office Action by an examiner and his/her supervisor… Over in Europe the examination of inventive step begins with an opinion following which the applicant is invited to comment/amend.
