Drafting a patent application, including the claims and specification, is generally considered to be an art rather than a skill because no set guidelines govern the process. The attorneys involved, especially in big organisations, often prepare their own internal practices for drafting. Such practices evolve alongside the patent law in terms of legislation, case law, manuals and guidelines. This report outlines preferred practices for drafting software patent applications in view of a guideline for examining patent applications related to computer-related inventions (CRIs) published by the Indian Patent Office.
