With the EPO and UPC adopting different frameworks for inventive step, is there potential for conflicting decisions?
IP analysis: The European Patent Office (EPO) regularly applies the problem and solution approach when deciding whether an invention involves an inventive step. Central to this approach is identifying the technical differences between the invention and the closest prior art, and determining the objective technical problem to be solved in the light of the technical effect linked to those differences. The question of whether the technical solution of an invention is obvious is analysed with this technical problem in mind. Furthermore, a reasonable expectation of success is often required before a prior art teaching can be considered as an obvious solution to the technical problem. Hsu Min Chung, partner and patent attorney at HGF, considers the implications of the growing diverging inventive step frameworks adopted by the EPO and UPC, and whether there is potential for conflicting decisions.
