1, trade name and trademark are two different things, and there is no necessary connection. Trade name is the name of the company, which is generally the responsibility of the local industrial and commercial bureau. The same trade name can be used in different fields, such as "Xi 'an Ren Hao Catering Company, Xi 'an Ren Hao Technology Company"; Trademarks are symbols representing goods or services, which are registered and managed by the State Trademark Office. Once a trademark is registered on the same kind of goods or similar goods, it enjoys the exclusive right nationwide, and others cannot use the trademark on the same kind of goods or similar goods without permission.
2. Sometimes they are the same, sometimes they are different. For example, well-known Haier and Gree, the trademarks of their main products are also Haier and Gree; Another example is Taobao, Ant Financial, and Box Horse Fresh Life. Everyone knows that it is the brand of Alibaba. This is the inconsistency between the company name (trade name) and the trademark. There are a lot of two situations, so I won't list them one by one.
From the above two points, we can basically see that there is no necessary connection between the two, not to mention your situation, one is in Tianjin and the other is in Xi 'an.
3. However, we should pay attention to one thing. For example, Tianjin Ren Hao Science and Technology Company registered the trademark of "Good Man" in the category of science and technology products, while Xi 'an Ren Hao Technology Co., Ltd. was not registered, but they were habitually confused. If shorthand methods such as "good man" and "good man technology" are applied to similar scientific and technological products, there is a risk of infringement.
4. There are two other special cases. 1. When a company's trademark becomes a well-known trademark, a company with the same trademark or the same brand name registered in other fields after that time may be considered as infringement if it is malicious. I have had such a lawsuit and lost it in malicious circumstances. 2. The enterprise has a registered company in the State Administration for Industry and Commerce, such as "Good Man Technology Co., Ltd.", and the company name does not contain geographic information. Generally speaking, other local industrial and commercial bureaus no longer accept the registration of "good people" companies with the same brand; This situation may also happen when the other party has a well-known trademark.
5. If you exclude special circumstances, your situation can be considered as risk-free or extremely low. There are so many commonly used Chinese characters that companies with the same name are very common. As long as the other party is not a well-known enterprise, there will be no problem if you don't do bad things maliciously.
