This examiner grants 14% of resolved cases

Analysis

Basia Anna Ridley serves in Tech Center 4100 and Art Unit 1723, where she has 37 resolved cases. Her allowance rate of 13.5 percent is very low, indicating a highly challenging prosecution environment. This 13.5 percent rate suggests that obtaining a patent from this examiner is a difficult outcome and requires a very strong and well-supported application.

The median days to allowance for the few successful cases is 1081. This 1081 day period shows that even when an allowance is achieved, the process takes a significant amount of time. With 37 resolved cases, the data highlights the substantial hurdles faced by applicants in Art Unit 1723 when trying to navigate the 1081 day timeline.

The interview lift is recorded at 1.7 percent. This 1.7 percent lift is minimal, suggesting that interviews have not historically provided a large boost in the probability of allowance. Given the 13.5 percent baseline allowance rate, practitioners should be prepared for a rigorous process where even direct communication may not significantly alter the 1081 day path to a resolution.
