According to LawStreet, Applied Materials recently filed a lawsuit requesting the court to make a declaratory judgment of non-infringement on two patents owned by the defendant Demaray LLC. The reason for this lawsuit was Applied Materials’ concerns about the lawsuits Demaray filed against several of its customers, accusing them of infringing on semiconductor manufacturing patents and involving Applied Materials.

Application materials pointed out in the litigation document that Demaray’s lawsuit against its customers cast a “dark cloud” on the company’s products, threatening the company’s business, its relationships with customers and partners, and the sales of reactors. There was a dispute between Demaray that could be tried by the court.

The complaint alleges that Applied Materials is an American company that provides technology and products for semiconductor manufacturing, including but not limited to reactors in the "Endura" product line. Demaray is a company founded by Dr. Richard Ernest Demaray, who is the designated inventor of the patent in this case. Demaray was established to provide portfolio-related R&D activities, intellectual property demonstration and development, and new product applications.

It is reported that Demaray mentioned the name of Applied Materials in the previous lawsuits against Samsung and Intel. Applied Materials feared that it might be sued next, and therefore requested the court to make a non-infringement judgment. For example, Applied Materials cited a complaint in which Demaray accused Applied Materials’ customers of manufacturing, using, selling, supplying, or causing the supply of semiconductor manufacturing equipment including magnetron sputtering reactors to "infringe its patent rights and was also identified in the complaint as "From Applied Materials."

In addition, Applied Materials stated that the company’s reactors in the “Endura” product line did not directly or indirectly infringe any claimed patent rights of Demaray, and briefly explained the differences in the composition and process of its products.
