Copyrights expert witnesses may opine on copyright infringement, copyright notice, and copyright limitations. On their website, the ABA Section of Intellectual Property Law defines what copyright is:
Copyright is a form of protection provided by the laws of the United States (title 17, U.S. Code) to the authors of “original works of authorship” including literary, dramatic,
musical, artistic, and certain other intellectual works. This protection is available to both published and unpublished works. Section 106 of the Copyright Act generally gives the owner of copyright the exclusive right to do and to authorize others to do the following:
To reproduce the copyrighted work in copies or phonorecords;
To prepare derivative works based upon the copyrighted work;
To distribute copies or phonorecords of the copyrighted work to the public by sale or other transfer of ownership, or by rental, lease, or lending;
To perform the copyrighted work publicly, in the case of literary, musical, dramatic,
and choreographic works, pantomimes, and motion pictures and other audiovisual works;
To display the copyrighted work publicly, in the case of literary, musical, dramatic,
and choreographic works, pantomimes, and pictorial, graphic, or sculptural works, including the individual images of a motion picture or other audiovisual work; and
In the case of sound recordings, to perform the work publicly by means of a digital audio transmission.
In addition, certain authors of works of visual art have the rights of attribution and integrity as described in section 106A of the 1976 Copyright Act. For further information,
