Utah and other states have laws that specifically state anything you create on you own time with your own equipment that is unrelated to your employer is yours, regardless of what any contract says. Unfortunately, there's plenty of room for ambiguity around what "unrelated" means. Not as good as California's law, but still something. See section 1, about half way down the first page: https://le.utah.gov/xcode/Title34/Chapter39/C34-39_1800010118000101.pdf https://le.utah.gov/xcode/Title34/Chapter39/C34-39_180001011... Check your own state's laws.
