Analysis

Hai H Huynh is a high-volume examiner operating in Tech Center 3700 and Art Unit 2834. With 1256 resolved cases, the examiner has one of the most extensive records in the dataset. This large volume of 1256 cases ensures that the associated metrics are highly stable and provide a very reliable foundation for patent prosecution strategy.

The examiner maintains an exceptionally high allowance rate of 93.4 percent. This 93.4 percent rate suggests that the vast majority of applications in this docket eventually reach a grant. Furthermore, the median time to allowance is 662 days, which indicates a very efficient examination process. Practitioners can expect a relatively quick resolution when working within this 662-day median timeframe.

The interview lift is 7.1 percent. While this 7.1 percent lift is positive, its relatively small magnitude is likely a reflection of the already high base allowance rate. In an environment where 93.4 percent of cases are allowed, the incremental benefit of an interview is naturally limited. Nevertheless, the combination of high efficiency and a high success rate makes Art Unit 2834 a favorable venue for applicants in Tech Center 3700.
