Two or more trademarks can be registered for the same product. There is no limit to the number of countries that can register trademarks on the same product.

There are two situations for your reference:

1. A trademark has been registered on a certain product, and it has gained a certain reputation after a period of market operation. In order to prevent Others use the same or similar trademark as one's own on the same or similar goods, that is, registering several similar trademarks on the same goods. For example, Wahaha Group not only registered the Wahaha trademark for children's drinks, but also registered Hahawa, Wahawa, etc. If these names are not registered, it remains to be determined whether it constitutes infringement when others use these names on the same product. But once registered, it will inevitably constitute infringement.

Second, focus on one trademark and use different trademarks on different series of products of the same type, thereby segmenting the market and increasing the share of the entire market. For example, Wuliangye Group is guided by the Wuliangye trademark, and has continuously launched Wulianghuang, Wangliangchun, etc. under it to achieve the occupation of different levels of the market.
