Before, Shandong Bittel Electronic industrial co., LTD (Bittel) filed a lawsuit against Beijing Cetis Science and Technology co., LTD (Cetis) for trademark infringement to Beijing Chaoyang District People's Court. In the meantime, Cetis filed a trademark revoking application to Trademark Review and Adjudication Board (TRAB), asking for revoking Bittel's No 4359350 trademark "TELEMATRIX". After the trademark "TELEMATRIX" revoking, Bittel filed an administrative lawsuit against TRAB to Beijing First Intermediate People's Court. The Court affirmed TRAB's revoking adjudication. In January 2014, Bittel appealed to Beijing Higher People's Court. In March 2014, the Court rejected Bittel's appeal and maintained TRAB's revoke adjudication. Then, Bittel filed a review application to China's Supreme People's Court, and the court affirmed the effective judgments and dismissed Bittel's application, on the ground that trademark "TELEMATRIX" of Cetis was famous on telephones; Bittel should be aware of "TELEMATRIX" trademark; Bittel's trademark was infringement for Cetis's trademark.
