Tech Center 3600 • Art Units: 3626

This examiner grants 0% of resolved cases

Analysis

Bill Chen, an examiner in Tech Center 3600, has a record of 13 resolved cases with an allowance rate of 0.0%. This rate in Art Unit 3626 indicates an extremely challenging environment where none of the 13 cases have resulted in an allowance. The median time to allowance is 1010 days, although this figure must be interpreted in the context of the 0.0% allowance rate. Practitioners should be aware of the significant hurdles presented by this 0.0% rate.

The interview lift is also 0.0%, suggesting that interviews have not yet led to an allowance in the 13 resolved cases. This 0.0% lift, combined with the 0.0% allowance rate, highlights the difficulty of securing a grant with this examiner. The 1010-day median pendency provides a timeline for the cases that have been resolved, but the lack of allowances is the most critical factor for strategy in Tech Center 3600. Applicants should carefully consider their approach given the 13 resolved cases and the 0.0% success rate.
