I am looking for some online tools to help me preventing my digital products from cloning/copying under DMCA legally. I am a PHP/WordPress developer, selling some premium plugins on my site, I found a man who is selling the items matching with a couple of items I coded originally but I am confused how I will verify my ownership if I proceed legally?
I apologize if I posted this question on wrong place, but any help regarding my question/request will be highly appreciated.
Thanks.
