Analysis

Tom Y. Lu is an examiner in Art Unit 2624 of Tech Center 2600. Across 965 resolved cases, the examiner maintains a high allowance rate of 87.5 percent. This indicates a very favorable environment for securing patent grants. Practitioners can use the 87.5 percent figure to communicate a high degree of confidence to clients regarding the likelihood of a successful outcome in this unit.

The interview lift is 3.6 percent. This low figure suggests that interviews have a minimal impact on the already high probability of success. Practitioners may find that the 87.5 percent allowance rate is driven more by the examiner's approach to written prosecution than by verbal engagement. While the 3.6 percent lift is positive, it indicates that an interview is rarely the deciding factor for an allowance with this examiner.

The median days to allowance is 902. This timeline provides a clear expectation for the duration of the prosecution cycle, lasting approximately two and a half years. The combination of an 87.5 percent allowance rate and a 902-day median suggests a reliable and efficient path to allowance. These metrics allow for precise planning and effective management of client expectations.
