Yamaha Motor Co., Ltd. (The "Company") filed a patent infringement lawsuit against IAI Corporation ("IAI", head office: 416-4, Obane, Shimizu-ku, Shizuoka City, Shizuoka Prefecture, Japan) today in the Osaka District Court, in which the Company contends that the robot controllerNote1 and linear-motor single-axis robotNote2 manufactured and sold by IAI infringe the Company's patent rights* (Patent Nos. 3542615 and 4105586) and seeks prohibition of the manufacture and sales of both products, as well as compensation for damages in respect to the infringement.
The Company had been trying to reach an amicable resolution of the patent infringement issue through negotiation, but IAI rejected the Company's proposal for an out-of-court settlement. Under the circumstances, the Company determined that it would be difficult to resolve the issue through negotiation; thus, it was compelled to file the lawsuit.
The Company counts its intellectual property rights as core management resources, and will continue to vigorously defend against any infringement upon them.
