Questão jurídica principal
Whether a site inspection could be ordered as precautionary evidence under Art. 158 ZPO in a patent dispute.
Decisão extraída
Yes, a site inspection may be ordered under Art. 158 Abs. 1 lit. b ZPO in patent matters if a protected interest is made plausible; Art. 77 PatG is not an exclusive prerequisite.
Fundamentação extraída
The general ZPO mechanism applies independently of the special patent description measure. However, the applicant must make plausible a concrete substantive claim and a protected interest in taking evidence; mere abstract desire to explore chances is insufficient.
