Please refer to this post as: , ‘Patent case: Ruling No. 159/2017, Spain’, Kluwer Patent Blog, May 23 2018,

In preliminary injunction proceedings, the influential Barcelona Court of Appeal held that reasons of “congruence” bind the court to basing the assessment of inventive step strictly on the particular prior art document chosen as the closest prior art by the party challenging its validity, regardless of whether that choice is technically and objectively justified. This could kick start a worrisome trend in Spanish revocation proceedings that is deeply inimical to the proper application of the problem-solution approach. The Court also made findings on the impact of decisions of the Opposition Division on Spanish injunctions.
