NL – Nikon v. ASML / Case No. 3

Posted: August 2nd, 2018

Nikon Corporation v. ASML Holding N.V., ASML Netherlands B.V. and ASML Systems B.V., District Court of The Hague, 1 August 2018, Case No. ECLI:NL:RBDHA:2018:9236

This is case no. 3 of 11 patent cases between Nikon and ASML.

Nikon unsuccessfully claims that ASML infringes Nikon’s EP 734 relating to an ‘Exposure apparatus, exposure method, and method for producing device’.

According to the Court, Nikon did not sufficiently establish that ASML in its machines uses a reference which is covered with a light-transmissive material.
