Analysis

Examiner Ben M. Rifkin works in Tech Center 2600 and Art Unit 2122. The examiner has 328 resolved cases, providing a solid foundation for analyzing prosecution behavior. The allowance rate is 44.2%, which indicates a challenging environment for applicants. This 44.2% rate suggests that practitioners should be prepared for a detailed and potentially difficult examination process.

The interview lift is 17.1%. This figure shows that interviews provide a notable benefit, increasing the likelihood of an allowance. While the lift is not as high as some other examiners, the 17.1% increase still represents a valuable strategic option for advancing a case toward a successful conclusion.

The median days to allowance is 1822. This is a relatively long pendency, and practitioners should communicate this 1822-day timeline to clients to manage expectations. The 328 resolved cases suggest that the examiner's trends are consistent in Art Unit 2122. Given the long median pendency and the moderate interview lift, a focused prosecution strategy that includes early communication may be beneficial for navigating this environment.
