Analysis

Alison Claire Gerhard examines cases in Tech Center 1700 and Art Unit 1681. With 43 resolved cases, the examiner has an allowance rate of 39.5%, showing a challenging environment for applicants. This low rate indicates that the majority of applications do not reach a grant, requiring practitioners to be well-prepared for potential rejections and a rigorous examination process.

The interview lift is 24.4%, suggesting that interviews are a highly effective strategy for securing an allowance with this examiner. The substantial lift indicates that direct communication can help clarify complex issues and move the application toward a grant more effectively than written correspondence alone. Practitioners should consider scheduling an interview to address examiner concerns directly and improve the probability of success.

The median days to allowance is 1369. 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 a high interview lift suggests that while the process is difficult, oral advocacy is a critical strategy for overcoming rejections.
