The subject heading is a key to the subject of the patent or application for patent. The Notation of Content (NOC) rather than the title of the document is used to provide a better description of the subject matter. The NASA Case Number is the prime access point to patent documents. The subject category number indicates the subject category in Section 1. Abstracts in which the citation is located. The NASA accession number denotes the number by which the citation is identified within the subject category. The NOC's are arranged under each subject heading in ascending accession number order.
