Analysis

Crystal L. Hammond is an examiner in Tech Center 2800, assigned to Art Unit 2819. With 934 resolved cases, the examiner has an extensive track record that provides a high degree of predictability for practitioners. The allowance rate is 87.8 percent, which is quite high and suggests a very favorable environment for securing a patent grant.

The interview lift percentage is 3.1, which shows that interviews provide a small but positive benefit in increasing the chances of an allowance.
