Trademark infringement is ubiquitous, but for some businesses, they will not take it seriously if it does not cause substantial harm to their interests. However, if a trademark infringement lawsuit is filed against him, there is a statute of limitations for trademark infringement lawsuits. So how long is the statute of limitations for trademark infringement lawsuits? There is nothing special about the statute of limitations for trademark infringement and general infringement. According to the general principles of my country's civil law, the statute of limitations for trademark infringement is two years, and the statute of limitations is calculated from the time when the person knew or should have known that the right had been damaged. If the infringement is a one-time infringement, there will generally be no problem in applying the two-year statute of limitations. However, if the infringement is continuous and the trademark owner knew or should have known about it for more than two years, the question of whether protection is needed will arise. One opinion is that the provisions of the General Principles of Civil Law should be strictly applied. Since the trademark owner clearly knows that there is infringement but ignores the statute of limitations and fails to take timely measures, he should naturally bear the consequences of not being protected; another opinion is that for continuous trademark infringement, he should bear the consequences of not being protected. If an intellectual property infringement has been committed for more than two years from the date the right holder knew or should have known to the date the right holder filed a lawsuit in the People's Court, the People's Court will not simply reject the right holder's action on the grounds that the statute of limitations has expired. Litigation claim. During the period when the intellectual property rights are protected by law, the People's Court shall order the defendant to stop the infringement. The amount of infringement damages shall be calculated forward two years from the date when the right holder files a lawsuit with the People's Court. Infringement damages exceeding two years shall not be protected. .
