Whether it is an infringement to use someone else’s trademark for store advertising depends on whether the other party’s trademark has been registered and whether it will cause misunderstanding to the public. According to Article 76 of the "Regulations for the Implementation of the Trademark Law", any use of a mark that is identical or similar to another's registered trademark on the same or similar goods as a trade name or product decoration to mislead the public shall fall under Article 5 of the Trademark Law. Infringement of the exclusive right to use a registered trademark as stipulated in Paragraph 2 of Article 17. Therefore, the other party's trademark has been registered and the perpetrator's behavior is enough to mislead the public, so using someone else's trademark for facade advertising is an infringement. However, if the perpetrator’s behavior does not mislead the public and is only used in good faith, then using someone else’s trademark for facade advertising does not constitute infringement. If the other party's trademark is not registered, then using someone else's trademark for store advertising is not an infringement, but it may involve unfair competition.
