Is their a way to check if a certain product or information is registered with intellectual property rights?. well I bought a package online from some guy on a forum it included links to other public websites and information on how to obtain more information from public records. He made this information into a package and sold it on his site. I bought it and i sold it on ebay. Nowhere in the package or on the site is it implied that he has intellectual proprty rights. Is their a way to find out if he copyrighted it? if he didnt can he still sue me?
