British trademark law comes from tort law, which is different from most countries in continental Europe. The current Trademark Law was promulgated on 1938.

Since Britain began to protect the exclusive right to use trademarks by common law and equity in the17th century, it has been indirectly protecting trademark rights by prohibiting counterfeiting other people's goods for more than 200 years. 1862 promulgated the first written trademark law without introducing the registration system.

1875 after the introduction of the registration system, unregistered trademarks are still protected by prohibiting counterfeit goods (that is, common law), while registered trademarks are protected by both traditional protection and statutory law, that is, double protection. In this way, the fundamental difference between an unregistered trademark and a registered trademark is that the trademark owner of the former has the right to sue only when others counterfeit his goods, while the trademark owner of the latter has the right to sue under any circumstances, as long as his trademark is illegally used, whether it is counterfeiting his goods or other circumstances (such as using his trademark in advertisements or importing goods without permission).

In Britain, the examination of registration application is strict and time-consuming, while the scope of registered trademarks is narrow, such as service trademarks, which cannot be registered. When examining the application for registration, the competent authority mainly determines the identifiability and degree of the trademark, secondly determines whether the trademark is deceptive, and also observes whether it conflicts with the law, public order and prior rights. Among them, more than 10 review items are deceptive reviews, such as; Whether there are deceptive tips on product quality, product origin, product business scope, legal status or other exclusive rights of trademark owners; Whether it will be confused with the trademark of the original user, resulting in deceptive consequences, etc.

The validity period of a registered trademark in Britain is 7 years, which can be extended indefinitely, and each extension period is 14 years.

According to the British trademark law, as long as one of the registered joint trademarks has not stopped using in trade activities, the whole joint trademark meets the requirements of "use" and remains valid. If a registered trademark has not been suspended for seven years, there is no dispute or the dispute cannot be established, it can become an undisputed trademark.
