This examiner grants 34% of resolved cases

Analysis

Mehmet Yesildag is an examiner in Art Unit 3623 within Tech Center 3600. He has handled 303 resolved cases, resulting in an allowance rate of 34.0 percent. This low rate suggests a challenging environment for applicants, where the majority of cases do not result in a patent grant. The 34.0 percent allowance rate reflects a high level of scrutiny applied to patent applications in this art unit.

The median time to reach an allowance is 1477 days, which is one of the longer durations for patent prosecution. Despite the difficult baseline, the interview lift is 28.1 percent, indicating that verbal communication can significantly improve the chances of success. Practitioners should consider the 28.1 percent lift as a vital tool for navigating the 1477-day median pendency. Engaging in an interview may help clarify technical points and move the application toward a grant more effectively than written responses alone. With 303 resolved cases, the examiner's data highlights the importance of a persistent and communicative strategy.
