Shanghai, China May 21, 2019 --- The Shanghai Intellectual Property Court has carried out a seizure on Suzhou Crystal Clear Chemical Co., Ltd. (“SCCC”) E-Grade H2O2 factory in Suzhou on May 20th, to preserve evidence of suspected patent infringement. Solvay S.A. (“Solvay”), the leading supplier of Electronic Grade (EG) hydrogen peroxide for the semiconductor industry, had filed a patent infringement lawsuit against SCCC on March 7, 2019, claiming infringement of Solvay’s granted patent ZL 200480028732.6. The patent is related to a purification process to manufacture electronic grade hydrogen peroxide (H2O2).

EG H2O2 is widely used in the wet cleaning step of semiconductor manufacturing process as well as other electronics applications. The most advanced semiconductor producers require extremely consistent and exceptionally high purity H2O2 down to single digit parts per trillion metallic impurities.

The Solvay Group is also manufacturing several grades of EG H2O2, amongst others in PRC, including Interox® Pico and PicoPlus grades.

Solvay enforces its intellectual property rights against suspected unauthorized use. In that regard, Solvay has sued SCCC for allegedly infringing a Solvay’s patent related to processes for purifying EG H2O2. Specifically, Solvay believes that SCCC’s EG H2O2 purification process infringes several claims under Solvay’s granted patent ZL 200480028732.6.
