Tech Center 2800 • Art Units: 2838 2839
This examiner grants 80% of resolved cases
Shahzeb K. Ahmad examines applications in Art Unit 2838 within Tech Center 2800. The examiner has 395 resolved cases, which support an allowance rate of 79.7 percent. This high rate indicates a generally favorable environment for patent applicants.
The interview lift percentage is 4.2, suggesting that while interviews are helpful, they provide a specific statistical boost alongside the 79.7 percent baseline allowance rate. The median days to allowance is 832, reflecting the prosecution timeline. Practitioners can rely on the 395 resolved cases to gauge the examiner's consistency. The 832-day median duration combined with the 79.7 percent allowance rate suggests that most applications proceed toward allowance with or without the 4.2 percent lift from an interview. This 4.2 percent lift can still be useful for addressing specific technical rejections within the 832-day period.
