I'm wondering if I need to start protecting the IP of my app and would appreciate any thoughts you more experienced developers may have. My user base is only about 120 users, but it's a specialized high priced app. Recently I saw someone saying they were going "Make a spreadsheet version of xyz app" I mean seriously...more power to them if they want to try black box 40,000 lines of code...spend 1000 hours doing it to save a couple hundred bucks...have at it. I just don't want to them to use the name of my app. Patent is out of the question, I'd never make the money back. Could I copyright or trademark the app name/ip. Again, appreciate any thoughts or links to study materials.
