Unified Patent Court Agreement

ARTICLE 55

Reversal of burden of proof

(1) Without prejudice to Article 24(2) and (3), if the subject-matter of a patent is a process for obtaining a new product, the identical product when produced without the consent of the patent proprietor shall, in the absence of proof to the contrary, be deemed to have been obtained by the patented process.

(2) The principle set out in paragraph 1 shall also apply where there is a substantial likelihoodthat the identical product was made by the patented process and the patent proprietor has been unable, despite reasonable efforts, to determine the process actually used for such identical product.

(3) In the adduction of proof to the contrary, the legitimate interests of the defendant in protecting its manufacturing and trade secrets shall be taken into account.
