You must ensure that your project and all of its content does not infringe on existing trademarks and patents. This includes product name, ideas, images, videos, animations and so on.
The easiest way is to google your product name and check to see if there are any existing registered companies or applications that go by the same name and/or functionality. You should also use the United States Patent and Trademark Office website at http://www.uspto.gov/ and ensure that you are not in violation of any existing trademarks and patents.
Failure to adhere to the above, is legally termed as being “willfully ignorant” and may lead to legal action against you and your team.
