Can I sue for short video without applying for a patent?

I can't. Short videos can't be sued if they don't apply for a patent, and they can't be held accountable if they don't apply for a patent and are imitated. They are not protected by law, and only by owning patents can they be held accountable according to law; Prosecution is the act of bringing a lawsuit to the court according to law and asking the court to hear a specific case. The prosecution of criminal cases is to ask the court to convict and sentence the defendant through trial.
