3M patent suit over metal mesh touch screen tech

3M and 3M Innovative Properties Co. filed a patent infringement lawsuit in federal district court in Wilmington, Delaware, against Elo Touch Solutions Inc.

The suit alleges that certain Elo Touch projected capacitive products infringe 3M’s US Patents 8,179,381, 8,274,494, 8,704,799 and 9,823,786.

“Metal mesh conductor technology is widely used in the construction of projected capacitive touch sensors for consumer and commercial applications,” said 3M.

“Metal mesh conductors have broad applicability across touch sensors of all sizes, in particular, large-format touch sensors often utilized in interactive whiteboards, conferencing systems, casino gaming machines, digital signage displays, and fast-food self-ordering systems.”

Makoto Ishii, vice president and general manager, 3M Display Materials and Systems Division, said: “3M strives to provide its customers with the most innovative materials and solutions for their products.

“The company is committed to protecting its investments in research and development for projected capacitive technology and vigorously defends its intellectual property rights.”
