Copyright protection is available to literary works, audiovisual works, motion pictures, phono-records, pictorial, graphic and sculptural works, sound recordings, and for the display and performance of such works. The term literary works include works expressed in words, numbers or symbols, including computer programs, and the term audiovisual works is not limited by the type of media that the work is stored on or in. Since March 1989, copyright protection has not required registration, but the United States provides significant incentives and additional protection for copyright owners who register their works and thus it makes sense to obtain such registration if there is a concern about infringement by others. We assist clients in determining what works warrant registration, how frequently to obtain additional registrations and prosecuting such registrations. We also represent clients when a claim of infringement has been asserted against the client and when the client needs to assert such claims against others.
