This examiner grants 36% of resolved cases

Analysis

Pierre Paul Eleniste serves in Art Unit 1622 of Tech Center 1600 and has managed 93 resolved cases. The examiner has an allowance rate of 35.5 percent. This lower rate indicates a challenging prosecution environment where applicants must be prepared for rigorous scrutiny of their claims and a higher likelihood of initial rejections. The 93 resolved cases provide a clear picture of the examination hurdles in this unit.

The median time to allowance is 1317 days, reflecting a long-term engagement for those seeking a patent. However, the data highlights the effectiveness of interviews, which provide an interview lift of 31.2 percent. This substantial lift suggests that personal engagement with the examiner is an effective way to overcome rejections and improve the odds of a grant. Given the 35.5 percent allowance rate, leveraging the 31.2 percent lift is a critical tactical consideration for any practitioner appearing before this examiner.
