Bridgestone announced that it has received a favorable ruling from the Shanghai Intellectual Property Court in its lawsuit regarding the infringement of patent rights against major Chinese tire manufacturer, Fangxing Rubber.

In September 2017, the Company filed a lawsuit with the Shanghai Intellectual Property Court. The lawsuit claimed that tire manufacturing and sales activities conducted by Fangxing utilized the tread pattern of truck tires for which the Company has taken out a patent and that these activities were therefore in violation of the Company’s patent rights. In May 2018, the Shanghai Intellectual Property Court upheld Bridgestone’s claim and ordered Fangxing to cease activities that are in violation of the Company’s patent rights and pay damages to the Company in the amount of approximately 620,000 Chinese yuan (US$90,000).

The violated patent rights pertained to Bridgestone’s R118 truck tire tread pattern (see diagram below). The R118 truck tire tread pattern was developed proprietarily by Bridgestone for China and other Asian markets.
