1. A registered trademark can be sold if it is not used. After a trademark is approved for registration, it should be used as soon as possible, and the evidence of use (such as production, sales, processing, etc.) should be kept. Article 49 of the Trademark Law stipulates that any unit or individual has the right to apply to the Trademark Office for cancellation of a registered trademark after it has been successfully used for three consecutive years without justifiable reasons.

2. When using a trademark, don't change too much at will. The trademark logo used shall be consistent with the registered trademark logo applied for approval at that time. In the process of using a trademark, an enterprise can only enlarge or shrink it in proportion, and cannot change the text of the trademark by itself. Tip: You may not change the traditional characters of a trademark into simplified characters. If the appearance after the change is similar to the registered trademark of others, it may also constitute trademark infringement.

3. When the company changes its name, it shall change its trademark in advance. Where the ownership of a trademark changes, it shall go through the corresponding transfer formalities at the Trademark Office in time. For example, if some companies cancel their trademarks, they will not be able to transfer them.

4. The trademark license shall be filed. A trademark owner may authorize others to use his registered trademark by signing a trademark license contract. Here, it is suggested that if the trademark owner is allowed to use another person's registered trademark, he should urge the trademark owner to go through the trademark license filing procedures in time, which is a layer of protection for his trademark license.

5. In order to prevent dilution of the distinctiveness of their trademarks, trademark registrants should not rely entirely on the examiners of the Trademark Office. If your competitors or your original partners apply for a trademark similar to yours, you should raise an objection in time. Otherwise, if his application is successful, it will be difficult for you to pass. Note: After the trademark is announced, the objection period is only three months. During this period, any objection can be raised, otherwise it will be out of date.

6. In order to expand the scope of use, a registered trademark should be added. The application for registration must be classified in accordance with the relevant provisions. After approval, the approved goods or services shall prevail. If a registered trademark needs to be used in other different kinds of goods or services, it must apply for registration separately.

7. The registration of Class 35 is a universal trademark, so registration is right. If an enterprise does not want to invest too much money in trademarks at the beginning of its operation and ignores the registration of the 35th category, it must be registered after the enterprise has developed for a period of time. Because these 35 categories of trademarks are comprehensive, such as e-commerce, online sales and online services, they are all in these 35 categories, so even if they are not used, they must be registered. It is troublesome to be maliciously squatted by others.

8. The trademark shall be renewed as soon as possible, and the validity period of the trademark is 1 years. After the expiration of a trademark, an application for renewal shall be filed with the Trademark Office within the first 12 months or the last 6 months. A trademark that has not been renewed will be declared invalid. After successful trademark registration, it is not once and for all. We should continue to pay attention to the trend of the Trademark Office and guard against similar trademarks and different types of similar trademarks in the market!
