that in theory is correct but in practice a sentence or few lines of code don't let me fight for them in court.
Pls dont bother to answer if you do not have a proof that a simple sentence or a simple line of code has any meaning for copyright in the court. And no i dont mean the few sentences that are actually copyrighted since they are catchphrases to specifics. No i mean a general sentence, or line of code.
Try to copyright "i = i + 1". Then we can continue this talk.
