In the invalidation action against the trademark No. 24725443, PATMARK ATTORNEYS, on behalf of GUANGZHOU TIGER HEAD BATTERY GROUP CO., LTD, filed a response. The applicant claimed that they have prior copyright and have put the copyright into use and made certain influence. PATMARK ATTRONEYS accepted the entrustment of TIGER HEAD BATTERY GROUP and undertook extensive evidence collection. It can prove that the actual use of the subject mark by TIGER HEAD BATTERY GROUP can be traced back to 1980s through massive fact and evidence, which is earlier than the formation time of applicant’s prior copyright and prior use time. Thus, the applicant did not have any prior right.
