Examiner: FENWICK, WARREN K

Analysis

Warren K Fenwick works in Tech Center 2800 and Art Unit 2852, where he has handled 651 resolved cases. His allowance rate is 89.7 percent. This high rate indicates a very favorable environment for patent applicants. The 89.7 percent allowance rate suggests that the vast majority of applications reaching a resolution result in a granted patent.

The interview lift is 0.3 percent. This negligible lift suggests that interviews do not significantly change the outcome of prosecution, likely because the baseline allowance rate of 89.7 percent is already very high. Most applications reach allowance through the standard written process. For the 651 resolved cases, the 0.3 percent lift indicates that verbal communication is rarely the deciding factor in the outcome.

The median days to allowance is 739. This duration indicates an efficient path to grant. With 651 resolved cases, the examiner's record shows a consistent pattern of high allowance rates and relatively quick resolutions. The 739-day median, combined with the 89.7 percent allowance rate, makes this a highly predictable and efficient environment for patent prosecution.
