On September 19, 2009, Oleg Zaitsev filed his patent application directed to a computer-hardware implemented anti-virus system. Zaitsev included a petition for accelerated examination along with pre-examination search results and an examination support document explaining the validity of the drafted claims.
In a December 10, 2009 telephonic interview, the applicant (through his attorney) agreed to add an additional limitation into the independent claims via examiner amendment. On December 17, 2009, the examiner from Art Unit 3685 issued a notice of allowance. The patent then issued February 2, 2010.
The less-than-three-month notice of allowance is especially important since patent applications from AU 3685 have an average pre-issuance pendency of over 5.5 years.
See Patent No. 7,657,941.
