If someone else steals your company's name (trademark, company name, etc.) and uses it in commercial activities, it is an infringement. This is because a trademark or company name is one of the intellectual property rights of a company and has independent legal status and protection rights.

If others use your company's font name without permission, it may cause the following problems:

Cause market confusion: others steal your company's font name and use it in their commercial activities. It will cause confusion in the market and have a negative impact on your company's reputation and customers.

Infringement of intellectual property rights: Trademarks or company names are one of the intellectual property rights of a company. Using other people’s names without authorization will infringe on other people’s intellectual property rights.

Violation of relevant laws and regulations: Misappropriating other people's names for commercial activities violates the "Trademark Law" and other relevant laws and regulations, and may be subject to legal sanctions.

Therefore, if you find that someone has misappropriated your company's name, you can file a complaint with the relevant department, apply for a trademark, etc. to protect your own rights and interests.
