15.13 Infringement-Elements-Ownership-Generally is a legal term used to describe the four elements that must be established in order for a claim of copyright infringement to be successful. These elements are: (1) ownership of the copyright; (2) copying of the copyright material; (3) substantial similarity between the two works; and (4) an intent to infringe. Ownership of the copyright may be established by showing that the copyright owner had legal title to the work or that the owner created the work. Copying of the copyright material may be established by showing that the defendant had access to the copyrighted material, or that the defendant had the opportunity to copy the work. Substantial similarity may be established by comparing the two works and showing that they have significant similarities. Finally, intent to infringe may be established by showing that the defendant was aware that his or her activities constituted copyright infringement.
