That question is a little off topic for these forums, but the short answer is: “Yes” in most countries. In the US, once a thing is in any fixed form - in a Word doc, a recording, a doodle on the back of a napkin - that is a work that can be copyrighted. The task then is to protect/enforce your copyright…which is a whole ‘nother conversation that’s far too large for me to coherently cover (or care about, on a weekend afternoon). THAT will differ from country to country, also.
