ASML : expresses disappointment that Nikon has opted for unnecessary and unfounded legal action over patents

• ASML believes Nikon's claims are without merit and will defend itself vigorously
• This sort of unnecessary patent litigation distracts from driving technology forward for the benefit of chip makers
• ASML has made repeated efforts to negotiate an extension of its patent cross-license agreement with Nikon
• Nikon has not engaged seriously with ASML and has instead chosen to commence legal proceedings

VELDHOVEN, the Netherlands, 24 April 2017 - ASML Holding NV (ASML) notes the announcement by Nikon that Nikon has filed a legal claim for alleged patent infringement against ASML in three countries. ASML has not yet received a notification of a legal action and categorically denies any infringement allegations.

ASML believes that Nikon's claim is without merit. We will defend ourselves vigorously against the allegations and we will consider all means at our disposal.

As disclosed in further detail in our annual report and on Form 20-F, ASML and Nikon in 2004 concluded a patent cross-license agreement. Some patents were perpetually licensed; for others, the license period ended on 31 December 2009. A transitional period, during which the parties had agreed not to bring suit, ended on 31 December 2014.

Peter Wennink, ASML President and Chief Executive Officer, said: "Nikon's litigation is unfounded, unnecessary and creates uncertainty for the semiconductor industry. Over the past years, ASML has made repeated attempts to negotiate an extension of its cross-license agreement with Nikon. We are disappointed that Nikon did not make any serious efforts to negotiate and has opted for legal action instead. We continue to believe that a negotiated outcome would have been preferable for the industry, which thrives on innovation and collaboration. This sort of unnecessary patent litigation distracts from what is truly important: driving technology forward for the benefit of chip makers. We should compete in the marketplace and not in court."
