Analysis

Kailey Elizabeth Cash is an examiner in Art Unit 1637 of Tech Center 1600. She has a total of 21 resolved cases in her profile. The allowance rate for these cases is 28.6%, which indicates a very challenging environment for securing a patent grant. This 28.6% rate suggests that a large majority of applications do not reach allowance. Practitioners should be prepared for a difficult prosecution path when their cases are assigned to this unit.

The data highlights a very high interview lift of 64.3%. This figure represents the increase in the probability of allowance following an interview compared to the baseline allowance rate of 28.6%. This 64.3% lift suggests that direct verbal communication with the examiner is an extremely effective strategy. Engaging in an interview may be the most critical step an applicant can take to improve their chances of success.

The median days to allowance for successful applications is 1351. This 1351-day figure provides a benchmark for the expected duration of the prosecution cycle. Given the 21 resolved cases and the 28.6% allowance rate, practitioners should anticipate a lengthy and difficult process. The 1351-day median and the 64.3% interview lift should be central factors in any prosecution plan for Art Unit 1637.
