PI Advanced Materials Wins Appeal in Non-Infringement Confirmation Lawsuit Against Kaneka
[Asia Economy Reporter Hyunseok Yoo] PI Advanced Materials, a specialized manufacturer of polyimide (PI) films, PI Advanced Materials, announced on the 17th that it won the appeal in the patent non-infringement confirmation lawsuit regarding PI (Polyimide) films against the Japanese chemical company Kaneka (KANEKA).
On August 10, 2016, PI Advanced Materials filed a patent non-infringement confirmation lawsuit at the United States Central District Court of California, asserting that the products currently produced and sold by PI Advanced Materials are uniquely developed products that do not infringe Kaneka's patents. Subsequently, on July 1, 2019, the United States Central District Court of California ruled in the first trial that PI Advanced Materials won and Kaneka lost, concluding the first trial.
Kaneka filed an appeal on July 29 of the same year, but on the 16th, the Federal Court of Appeals upheld the final ruling of the Central District Court, delivering a victory to PI Advanced Materials. Through this victory, PI Advanced Materials has once again legally confirmed that the PI products it currently produces and sells do not infringe on other companies' patents.

A company official stated, “This non-infringement confirmation lawsuit was conducted strategically and proactively to secure the continuity of the company's business activities while completely eliminating any grounds for dispute,” adding, “The victory is significant in that it removed patent issues related to the products currently produced and sold by the company.” The official further emphasized, “As aggressive sales activities have become possible in some regions and specific application markets where responses had been restrained, we plan to use this victory as a stepping stone to expand the market and sales, thereby solidifying our position as the undisputed global No. 1 PI company.”
