Joint trademarks generally refer to several similar trademarks registered by the same trademark owner on the same or similar goods. Among these trademarks, the one registered first or mainly used is the main trademark, and the rest are joint trademarks.

We should know that after a trademark is successfully registered, especially after it becomes famous, other similar trademarks will often appear intentionally or unintentionally on the same or similar goods. In our country, which has a vast territory, many enterprises, a late start to the market economy, and people's awareness of trademark law is in the "primary stage" and is still very immature, this phenomenon is inevitable. In addition, because different individuals have different intuitive feelings about the pronunciation, meaning, implication, composition, etc. of the words and graphics formed by the trademark, different subjective judgment results will appear. Therefore, it is very complicated to accurately judge whether two or more trademarks are similar. , so it is quite difficult.

Although, for these situations, we can, in accordance with the relevant provisions of the "Trademark Law", through the National Trademark Office, the Trademark Review and Adjudication Board for objection, dispute, improper cancellation of registration, or through the industrial and commercial administration department for "Anti-Unfairness" Competition Law (September 2, 1993) and other legal means to address protection. However, this kind of protection is always passive, the scope is limited, and it requires long-term and huge efforts for enterprises, especially cases such as objections, disputes, and improper cancellation of registration. It will take at least 2 years or more. If you are not careful, it is very likely that all your efforts will be wasted and the impact will be huge.

Therefore, the purpose of registering a joint trademark is not to use each registered trademark, but to build a firewall around the main trademark to play an active defense role and prevent others from registering and using similar trademarks. Trademarks allow those with impure motives to take advantage. At the same time, these trademarks can also serve as a reserve of trademarks. Once the market needs it, the trademark strategy can be proactively and conveniently adjusted and backup trademarks launched.
