The question is whether you can copyright computer programs and videogames. The Copyright Act was amended to expressly include the right to register computer programs and videogames.
What is a computer program and how can you copyright it?
A computer program is a set of statements or instructions to be used in a computer to provide a result. See 17 U.S.C. § 101; Stern Electronics, Inc. v. Kaufman, 669 F.2d 852, 855 (2d. Cir. 1982). Copyright protection extends to the copyrightable expressions embodied in the computer program. Computer programs are classified as literary works for the purposes of copyright. See Whelan Associates v. Jaslow Dental Laboratory, 797 F.2d 1222, 1234 (3d Cir. 1986). Also, copyright laws do not protect the functional aspects of a computer program (e.g., algorithms, formatting, functions, logic, system designs).
