Analysis

Lanny N. Ung operates within Tech Center 3600 and Art Unit 2191, where he has managed 512 resolved cases. His allowance rate is 71.3%, which indicates a generally positive environment for patent applicants. This rate serves as a benchmark for assessing the likelihood of a grant in this specific art unit. The 512 cases resolved by this examiner provide a robust sample for these performance statistics.

The median days to allowance for this examiner is 1231, suggesting a relatively long and deliberate prosecution process. However, the data shows an interview lift of 25.8%, which offers a substantial increase in the probability of success. This positive lift indicates that direct communication is a highly effective supplement to written advocacy. The 1231-day median pendency is an important figure for practitioners to communicate to their clients when setting expectations for Art Unit 2191.

Strategically, the 25.8% interview lift should be considered a primary option for overcoming rejections. While the 71.3% allowance rate shows that success is achievable, the 1231-day median suggests that the process requires patience. With 512 cases resolved, the examiner's tendencies are well-documented, allowing for more informed planning. Applicants should prioritize interviews to potentially expedite the 1231-day timeline and improve the odds of a grant.
