In theory patterns would protect the small innovative inventors - but in reality software patterns are used like nuclear weapons - to frighten anyone to not sue - or you would be sued back with a bunch of pattern like round corners, comments in source code, a program that can accept connections, etc... We however have copyright. So the big companies can't just copy your software and sell it as is... unless you open source it using a MIT licence, then they will copy it, make some closed source changes and compete with you.
