Yes, you can. 1. You can object to a trademark that has not been successfully registered. If you find that your trademark has been registered by others first, but the application of the cybersquatter has not been approved, you can remedy it by raising an objection. According to the provisions of China's Trademark Law, the trademark application shall be preliminarily examined by the Trademark Office of the State Administration for Industry and Commerce, and those who pass the examination shall enter the announcement period, and the announcement time shall be 3 months. Within these three months, eligible subjects can raise trademark objections. Those start-up companies that have registered their trademarks can prepare evidence materials through professional trademark agencies and file trademark objections with the Trademark Office within these three months. 2. A trademark that has been successfully registered may apply for invalidation. If a registered trademark has been approved for registration after a three-month announcement period, the company may request the Trademark Review and Adjudication Board of the State Administration for Industry and Commerce to declare the registered trademark invalid according to the provisions of Article 45 of the Trademark Law. The Trademark Law has a time limit of five years for the application for invalidation, that is, if the trademark has been registered for more than five years, it cannot apply for invalidation on the grounds of squatting (well-known trademarks are not limited by this time limit). If a party refuses to accept the ruling of the Trademark Review and Adjudication Board, he may also bring an administrative lawsuit to the people's court.
