Written by Mark Terry In its first decision on this Friday the 13th, the Board of Patent Appeals and Interferences (BPAI), reversed an Examiner’s 103 obviousness rejection based on the Examiner’s faulty inherency logic. I like this reversal because it highlights the Examiner’s burden and the consequences of not meeting that burden – i.e., a win for the Applicant. With regard to inherency, recall M.P.E.P. 2112 states that where an Applicant claims a composition in terms of a function, property or characteristic and the composition of the prior art is the same as that of the claim but the function is not explicitly disclosed
