Jiangsu trademarks are registered first and then approved by the Trademark Office, so that they can be used normally in the market. However, the approval of trademark registration is not the end of trademark application, but a turning point. At this time, the trademark means that the enterprise has a dominant position, and it can be protected by law, but what does the enterprise need to do after approval?

One of the most important points is that the use of trademarks cannot be changed without authorization. In other words, when an enterprise uses a trademark, it must be consistent with the trademark logo at the time of registration. It can be enlarged and reduced, but it cannot be modified. If an enterprise changes the original trademark text, it may infringe upon the trademark rights of others. Similarly, when the enterprise information changes, the trademark will also change.

Secondly, the trademark license is filed in time. A trademark owner may license his trademark to others by signing a trademark license contract, but the trademark owner must go through the corresponding filing procedures at the Trademark Office. If the trademark owner forgets, the licensee should also urge him in time, which is also the protection of his trademark license.

Proper market monitoring is also necessary. If similar trademarks are found, enterprises should raise objections in time. Enterprises should note that trademark objections have three months, during which any objections can be raised.

Moreover, which categories of trademarks are registered by enterprises can only be protected in these categories. If the trademark owner uses more goods or services than those originally approved for registration, it does not belong to the use of a registered trademark and is not protected by law. Unless the trademark owner increases the registration in the category to be involved, the trademark can still be protected by law after successful registration.
