Nikon is suing ASML and Carl Zeiss for using their chip know-how. ASML is denying that it has infringed any of Nikon’s patents. Zeiss is considering Nikon’s legal action unfounded.
Update – ASML also issued a press release on Nikon’s lawsuit, here are their main points:
- 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
