Kaneka Intends to Appeal Invalidity Decision in Lawsuit Against CoCrystal
Kaneka Corporation announced its intention to appeal an invalidity decision concerning its lawsuit against CoCrystal. The decision was issued by the U.S. Patent and Trademark Office.
Kaneka Corporation intends to appeal a decision by the U.S. Patent and Trademark Office (USPTO) regarding the invalidity of patents in a lawsuit filed against CoCrystal Technology (Jiaxing) Co., Ltd. The decision was issued on September 2, 2026.
Kaneka Corporation originally filed a complaint against CoCrystal in the U.S. District Court for the Eastern District of New York on October 5, 2023. The complaint alleged that CoCrystal had infringed upon certain Kaneka patents. The company has been involved in various patent disputes previously.
The USPTO's decision addresses the validity of the Kaneka patents that formed the basis of the initial complaint. This invalidity ruling presents a significant setback to Kaneka's efforts to protect its intellectual property in the relevant technology sector.
Kaneka has stated its intention to seek reconsideration of the ruling and to present further evidence supporting its patents. The company remains confident in the validity of its patents and plans to pursue its legal actions to safeguard its technological advantage.
