Legal analysis: It depends on the specific situation. The right to name is one of the basic rights of citizens. It belongs to the right of identity and is an absolute right. If your pen name overlaps with that of a well-known person, and that person's pen name is used before yours, it may constitute infringement.

Legal basis: "Trademark Law of the People's Republic of China" Article 52 Infringement of the exclusive right to register a trademark mainly includes the following types:

1. The owner of a registered trademark authorizes the use of a trademark that is identical or similar to the registered trademark on the same or similar goods.

2. The act of replacing a registered trademark without the consent of the trademark registrant and putting the goods with the replaced trademark back on the market. This behavior is also called reverse counterfeiting in theory.

3. The act of selling goods that infringes upon the exclusive rights of registered trademarks.
