The Trademark Law and its implementing regulations do not clearly stipulate the starting point of "three consecutive years". According to the current trademark trial practice, the starting point is generally the date when the applicant puts forward the claim for revocation of the application (the actual acceptance date of the Trademark Office), and three years are calculated forward. For example, if the applicant applies for cancellation and the Trademark Office accepts it on June 1, 215, the time limit for judging whether to save or not to use it is from June 1, 212 to May 31, 215. As long as the state of non-use lasts for more than three years, it conforms to the provisions of the second paragraph of Article 49 of the Trademark Law.
