What are the advantages of a lawfully registered trademark in Los Angeles?

Hi everyone, I am about to start a business and am in the process of gathering all the necessary documentation. When I consulted with the experts, the lawyer could not explain to me why I need to register a trademark. He just said that it is necessary if I don't want to get a fine. Of course, I was not satisfied with this answer, so I am now in search of a technology lawyer who can answer my question - what are the advantages of a lawfully registered trademark in Los Angeles?

It's a good thing you didn't work with an incompetent attorney, or it could have been much worse. In fact, it is mandatory to register a trademark for your own safety and the safety of the company. David Sharifi, a reputable tech lawyer https://techandmedialaw.com/ was interviewed about trademarks, and he mentioned that if you don't register it, if you plagiarize it, you can't sue in any way, but you can be sued for copyright infringement. And you won't be able to prove anything, even though your company has been using that trademark longer than the competitor. And if you do everything according to the law, you can use the main registration symbol, and your company will be on the list of the Patent and Trademark Office of the country, so no one can use your trademark.
