Bad English Warning!
The reason why I'm worrying about it is copyright infringement proplem.
what if someone copies my design in illegal way. Can I protect my copyright then without getting a patent?
Or, is it an idle fear?
/Sorry for all of you. I missed to make public that my mean is 'in puzzles I invented'
Without that word this post is very weird. I made a confusion to most of you. I'm sorry once more.
If I take picture of my puzzle's structure and post this, someone copies my design in illegal way. This post is questioning about it.
