The Defensive Publication Program allowed patent applicants to request publication of an abstract of their pending applications provided they waived their rights to a patent. The Defensive Publication Program was abolished in 1985 and the last defensive publication was published in 1988. Approximately 5,002 unexamined applications were published under the Defensive Publication Program during its twenty-year span.
Defensive publication numbers consist of three parts.
T 123 01
The prefix “T” indicates a technical disclosure. This is followed by a three digit number corresponding to the volume of the Official Gazette in which the defensive publication was included and a two or three digit document number.
The Statutory Invention Registration (SIR) Program was established in 1985 and abolished in 2013. Like the Defensive Publication Program, it allowed patent applicants to request publication of their pending applications provided that they waived their patent rights. Approximately 2,266 SIR documents were published from 1985 through 2014.
