1. Use other people's registered trademarks without their permission.
This kind of situation is a common infringement at present, because some trademarks are well developed, with high popularity and reputation, and there are more natural consumers. In order to attract these customers, some enterprises directly use other people's trademarks to mislead consumers, and then choose these enterprises to consume, but these enterprises actually infringe other people's trademarks.
2. Damage to the registered trademark of others.
Generally speaking, some small companies are maliciously attacking some trademark brands through some means, which leads to the decline of the brand's trademark reputation, and these small companies profit from it. However, once this situation is found out, it will also be judged to have infringed on other people's trademarks, and the infringer will bear certain legal responsibilities.
Third, make changes on the basis of other people's trademarks.
All trademarks have been confirmed that there are no identical or similar trademarks at the time of application. If you find that someone else's trademark is similar to your own trademark, it may be that someone else's trademark has just been changed on the basis of your own trademark, forming an approximate trademark, so this kind of behavior also belongs to infringement.
Fourth, there is a causal relationship between trademark infringement.
Because the fact of damage is no longer a constituent element of trademark infringement, causality is no longer a constituent element of trademark infringement for direct infringement of trademark rights. Only when trademark infringement damage occurs, the causal relationship between damage and damage facts should be considered.
These are the reasons for trademark infringement. If you encounter these situations in your life, you can take up legal weapons to safeguard your legitimate rights and interests. If there is no registered trademark, in order to avoid infringing on other people's trademarks, it is necessary to obtain the right to use the trademark through trademark registration or trademark transfer.
