1. Life Sciences and Pharma/ Biopharma Patent Litigation 1.1 Claimants/Plaintiffs to an Action The standing to bring patent infringement actions lies with the registered patent holder. Established case law confirms that exclusive licensees have the autonomous right to initi - ate patent infringement proceedings, provided they can demonstrate their status as exclusive licensees when filing the case in court. This can be achieved by either submitting a copy of the exclusive license agreement along with the initial statement of claim or, preferably, by registering a confirmatory license with the Italian Patent Office.

A statement that the party filing for revocation or declaratory relief is interested in doing business in the technical field relevant to the patent will normally suffice. A higher threshold normally applies to declara - tory actions of non-infringement when filed in the form of preliminary proceedings in that an addi - tional layer is required in relation to the urgency of the action, ie, the petitioner needs to estab - lish it would suffer irreparable harm absent the requested preliminary declaratory relief. 1.2 Defendants/Other Parties to an Action Patent infringement actions in the life sciences industry would normally target the infringing MA holder and the related Italian affiliate distribu - tor, along with any further party involved in the manufacturing and supply chain of the infringing generic or biosimilar product, as long as they are active on the Italian territory.
