Analysis

Ivan Alexander Castaneda is an examiner in Art Unit 2171 of Tech Center 2100. He has a total of 7 resolved cases in his profile. The allowance rate for these cases is 57.1%, which indicates a moderate environment for securing a patent grant. This 57.1% rate suggests that while success is possible, applicants may face some hurdles. Practitioners should be prepared for a standard examination process when their cases are assigned to this unit.

The data highlights a significant interview lift of 41.7%. This figure represents the increase in the probability of allowance following an interview compared to the baseline allowance rate of 57.1%. This 41.7% lift suggests that direct verbal communication with the examiner is a highly effective strategy. Engaging in an interview may be a critical step an applicant can take to improve their chances of success with this examiner.

The median days to allowance for successful applications is 1315. This 1315-day figure provides a benchmark for the expected duration of the prosecution cycle. Given the 7 resolved cases and the 57.1% allowance rate, practitioners should anticipate a relatively long process. The 1315-day median and the 41.7% interview lift should be primary factors in any prosecution plan for Art Unit 2171.
