Examiner: RONO, VINCENT KIPKEMOI

Tech Center 2800 • Art Units: 2891

This examiner grants 85% of resolved cases

Analysis

Vincent Kipkemoi Rono works in Art Unit 2891 of Tech Center 2800. The examiner has a total of 20 resolved cases, with an allowance rate of 85.0 percent. While the case count of 20 is lower than some peers, the high allowance rate indicates a favorable environment for patent applicants. This 85.0 percent rate suggests that the examiner is inclined to grant patents when the technical requirements are met, providing a positive outlook for new filings.

The interview lift is 18.8 percent, suggesting that interviews are a beneficial part of the prosecution strategy. Engaging with the examiner may help in clarifying complex technical issues and moving the application toward a grant, as shown by the 18.8 percent lift in success. This indicates that the examiner values the additional context provided during oral discussions. Practitioners should consider scheduling an interview early in the process to align on claim scope and address any potential rejections efficiently.

The median days to allowance is 1390. This relatively long duration suggests that while the probability of allowance is high, the process itself may take a significant amount of time to conclude. The 1390-day median is a critical factor for applicants to consider when planning their long-term intellectual property strategy. It highlights the need for patience and consistent engagement throughout a prosecution cycle that spans several years before reaching a final grant.
