If you or your company is thinking of entering the US market, you should familiarize yourself with what constitutes copyright, trademark, or trade secret material, and what is protected/not protected within each Intellectual Property (IP) category in the United States.
Doing so will go a long way to preventing you from unintentionally violating the IP rights of someone else (or some other entity), which could cost you thousands of dollars in fines and delay or prevent your entry into US markets.
