This examiner grants 27% of resolved cases

Analysis

Steven Maldonado works in Tech Center 3700 and Art Unit 3797. He has 26 resolved cases with an allowance rate of 26.9 percent. This low rate suggests a difficult path to allowance for most applicants. The median days to allowance is 1200, indicating a long prosecution process for those who are successful.

The interview lift is 42.9 percent, which is a significant positive factor. This suggests that while the 26.9 percent allowance rate is low, an interview can greatly improve the chances of success. Practitioners should use interviews as a key tactic to navigate the 1200-day median pendency and overcome the examiner's rigorous standards.

Top companies like Intuitive Surgical Operations Inc., Fujifilm Corporation, and Koninklijke Philips N.V. appear in his 26 resolved cases. Firms such as HOWARD & HOWARD ATTORNEYS PLLC, Studebaker Brackett PLLC, and ALG Intellectual Property | ISRG are also involved. The 42.9 percent interview lift is a vital tool for these applicants given the 26.9 percent allowance rate.
