Analysis

Michael T. Rozanski serves in Art Unit 3737 of Tech Center 3700. The examiner has a total of 921 resolved cases and an allowance rate of 69.2 percent. This data reflects a consistent track record across a large volume of patent applications, providing a reliable baseline for applicants. The 69.2 percent allowance rate suggests a balanced examination environment where success is achievable through diligent prosecution and clear technical disclosure of the invention's merits.

The interview lift is 28.8 percent, which is a strong positive indicator for the effectiveness of interviews. Applicants who engage in direct communication with the examiner are significantly more likely to achieve an allowance, as shown by the 28.8 percent increase in success rate. This suggests that the examiner values the interactive nature of oral advocacy to resolve technical disagreements. Practitioners should prioritize interviews as a key tactic for advancing prosecution and overcoming rejections more efficiently than through written responses alone.

The median days to allowance is 1195. This duration offers a benchmark for the expected time from filing to grant, helping applicants manage their expectations and strategic planning. The 1195-day median is a key metric for forecasting the timing of patent issuance and the associated costs. It provides a realistic view of the time commitment required to navigate the examination process and helps in the long-term planning of intellectual property assets.
