Following are some common traps in determining intellectual property rights, from Sharon K. Sandeen’s Intellectual Property Deskbook for the Business Lawyer (American Bar Association, 2008).
1. Ownership of a work of authorship (e.g., a painting or a book) does not include ownership of the copyrights.
2. Registered copyrights in pre-1978 works may exist even if a copyright registration certificate suggests they have expired.
