Lawyer Ma Yingqiu’s answer: The above is the answer to “Is it possible to use a trademark without authorization? What are the risks of not authorizing the use of a trademark?” I hope it can help you. First, by law, your friend is the trademark owner. Your unauthorized use of this trademark is infringement of your friend's trademark rights. Therefore, it is recommended that you apply for trademark authorization according to normal procedures. Trademark authorization, also known as trademark license, means that the trademark registrant authorizes others to use its registered trademark by signing a trademark use authorization contract. The authorized person engages in business activities (usually producing and selling a certain product or providing a certain service) as stipulated in the contract, and pays the licensor the corresponding fees - royalties; at the same time, the licensor provides personnel training, organizational design, operation management, etc. guidance and assistance. Secondly, if you use someone else’s trademark without trademark authorization, it will constitute trademark infringement and you may need to compensate others for their losses. According to the Trademark Law, the benefits obtained by the infringer due to infringement during the infringement period can be calculated based on the product of the sales volume of the infringing goods and the unit profit of the goods. Or the losses suffered by the infringed party due to the infringement during the period of infringement, including the reasonable expenses paid by the infringed party to stop the infringement, including investigation fees and attorney fees, can be based on the reduction in product sales caused by the infringement or the infringement. It is calculated by multiplying the product sales volume and the unit profit of the registered trademark product. Or the people's court may award a compensation of less than 500,000 yuan based on the circumstances of the infringement. The above are the answers to your questions, I hope they can help you.
