Would a serious competitor ever risk being sued by copying your code verbatim? Would copying just parts of your likely obfuscated codebase and trying to integrate it into their own codebase be more difficult than reverse engineering it? I don't think it's something to worry about. Someone that is smart enough to steal and use your code is smart enough to use a legal alternative.
