What should I do if the advertising language is stolen by the enterprise?

XD, look on the bright side. This is a common occurrence for a small advertiser like me. Don't say a slogan Sometimes the whole case is copied (at most, the place where the broken parts are changed). Be busy with life every day. How can I have the time and energy to go to court with them? Find a place where no one is crying and continue to leave my figure in every corner of the city!
