This examiner grants 37% of resolved cases

Analysis

Rajesh Khattar, based in Tech Center 3600 and Art Unit 3626, has resolved 559 cases with an allowance rate of 36.7 percent. This is a relatively low allowance rate, indicating a difficult prosecution environment. Furthermore, the median days to allowance is 1584, which is a very long timeline for the 36.7 percent of cases that successfully reach a grant.

Despite these challenges, the interview lift is 35.2 percent. This high lift suggests that interviews are a critical tool for success with this examiner. While the 36.7 percent baseline allowance rate is low and the 1584-day timeline is long, the significant impact of interviews indicates that direct communication is the most effective way to overcome rejections and move toward a patent grant.

Strategy for this examiner must focus on persistence and the use of interviews. The 35.2 percent lift is essential for improving the odds of success. Practitioners should advise clients of the 1584 median days to allowance and use interviews as a primary tactic to resolve rejections and potentially shorten the lengthy prosecution cycle in Art Unit 3626.
