On August 6, the USPTO reached another milestone, issuing patent no. 8,500,000. Design patents are rapidly approaching the 700,000 mark; it is likely that D700,000 will be issued in February 2014.
The USPTO abolished the Statutory Invention Registration (SIR) Program in March. The number of SIRs published during the 28 years the program was in existence was approximately 2,260. The number of SIRs per year has steadily decreased since the USPTO began publishing applications in 2001. Only 13 SIRs were published this year, almost twice as many as in 2012.
