Analysis

William Wong presents a more rigorous prosecution profile in Art Unit 2123. With 407 resolved cases, his allowance rate is 30.7 percent. This lower rate, combined with a median days to allowance of 1630, suggests that applicants face a difficult and lengthy path to securing a patent in Tech Center 2100. The 1630-day figure is particularly notable for its duration, requiring significant persistence from the applicant.

Despite these challenges, the interview lift is 27.8 percent. This is a significant figure, indicating that interviews are a vital tool for success with this examiner. Given the 30.7 percent baseline, an interview may be the most effective way to improve the odds of a grant. Practitioners should prioritize direct communication to navigate the prosecution timeline and leverage the 27.8 percent boost in allowance probability.
