According to relevant regulations, generally if you want to use your own trademark, you need to register your trademark with the relevant department, but there will also be a certain number of years, so the longest period after the trademark license contract expires How many years can’t be exceeded? According to relevant regulations, the maximum term of a trademark use license shall not exceed ten years. Let’s learn more about it together below. 1. The maximum term of the registered trademark license contract between the two parties cannot exceed 10 years and can be renewed. 2. Article 39 The validity period of a registered trademark is ten years, calculated from the date of approval of registration. Article 40 If a registered trademark expires and needs to be continued to be used, the trademark registrant shall go through the renewal procedures in accordance with the regulations within twelve months before expiration; if it fails to do so during this period, a six-month extension period may be granted . Each renewal of registration is valid for ten years, starting from the day after the expiration of the previous term of validity of the trademark. If renewal procedures are not completed upon expiration, the registered trademark will be cancelled. The Trademark Office shall announce the renewal of registered trademarks. 3. Article 43 of the Trademark Law: A trademark registrant may authorize others to use its registered trademark by signing a trademark license contract. The licensor shall supervise the quality of the goods used by the licensee using its registered trademark. The licensee shall ensure the quality of the goods using the registered trademark. If the registered trademark of another person is used with permission, the name of the licensee and the place of origin of the goods must be marked on the goods using the registered trademark. If the licensor permits others to use its registered trademark, the licensor shall submit its trademark use license to the Trademark Office for record, and the Trademark Office shall announce it. The trademark use license shall not be used against bona fide third parties without registration. 4. The licensee’s sale of inventory goods does not constitute trademark infringement. First, judging from the nature of the licensee’s behavior of selling trademarked goods, the sales behavior is not a direct trademark use behavior. Whether the product sales behavior constitutes infringement should be based on the goods sold by the seller. Determine whether the use of the above trademark is authorized. According to the provisions of Article 48 of my country's Trademark Law, the use of trademarks as mentioned in the Trademark Law refers to the use of trademarks on goods, commodity packaging or containers, and commodity transaction documents, or the use of trademarks in advertising, exhibitions, and Behavior used to identify the source of goods in other commercial activities. As far as product sellers are concerned, their behavior is not to use the trademark on the products, but to purchase the products from the manufacturer that have been affixed with the right holder's trademark and then put them into the market. Therefore, the seller has not implemented the trademark use behavior, and the product sales behavior is only a continuation of the trademark use behavior. Whether the sales behavior constitutes infringement depends on whether the previous trademark use behavior was licensed. If a product manufacturer uses the right holder's trademark on the products it produces without permission, the product will naturally be a product that infringes the trademark right, and the seller's subsequent sales of the infringing product will naturally also constitute infringement. On the contrary, if the goods sold by the seller are not infringing goods, the trademark owner naturally has no right to ban them. After the trademark license contract expires, although the licensee sells goods bearing the right holder's trademark, since the goods were legally produced during the duration of the license contract, they are not infringing goods. The licensee's subsequent sales The behavior does not constitute trademark infringement.
