Abstracts and Abbreviatures are U.S. Patent and Trademark Office publications of abandoned applications. Defensive Publications (the O.G. defensive publication and search copy) are U.S. Patent and Trademark Office publications of provisionally abandoned applications wherein the applicant retains their rights to an interference for a limited time period of 5 years from the earliest effective U.S. filing date. On May 8, 1985, the U.S. Patent and Trademark Office stopped accepting Defensive Publication requests and began accepting applications for Statutory Invention Registrations (SIRs), although there was an overlap period where both Defensive Publications and Statutory Invention Registrations were processed; see MPEP § 711.06 and § 711.06(a). Statutory Invention Registrations replaced the Defensive Publication program. However, requests for a statutory invention registration filed on or after March 16, 2013 will not be processed, as the provisions of pre-AIA 35 U.S.C. 157 governing Statutory Invention Registrations were repealed. See MPEP § 1101. Statutory Invention Registrations are numbered with document category “H,” beginning with “H1.” Defensive Publications and Statutory Invention Registrations are included in subclass lists and subscription orders.
Distinct numbers are assigned to all Defensive Publications published December 16, 1969 through October 1980.
For Defensive Publications published on and after November 4, 1980, a different numbering system is used.
A conversion table from the application serial number to the distinct number for all Defensive Publications published before December 16, 1969 appears at 869 O.G. 687. The distinct numbers are used for all official reference and document copy requirements.
