This examiner grants 38% of resolved cases

Analysis

Dennis Cherian George examines cases in Tech Center 1600 and Art Unit 1644. With 13 resolved cases, the examiner has an allowance rate of 38.5%, showing a challenging environment for applicants. This low rate indicates that more than half of the applications do not reach a grant, requiring practitioners to be well-prepared for potential rejections.

The interview lift is 72.7%, which is an exceptionally high figure. This indicates that interviews are an incredibly powerful tool for applicants to use when working with this examiner, as they dramatically increase the chances of success. The massive lift suggests that oral advocacy is far more effective than written correspondence alone in this examiner's practice.

The median days to allowance is 1308. This timeline indicates a standard prosecution duration for the tech center, requiring over three years to reach a final resolution. The combination of a low allowance rate and an extremely high interview lift suggests that while the process is difficult, oral advocacy is the most critical strategy for success.
