Analysis

Ryan N. Henderson is an examiner in Art Unit 3739, which falls under Tech Center 3700. He has managed 832 resolved cases, providing a robust data set for analysis. His allowance rate is 63.9 percent, which is a solid indicator of a fair examination process. This 63.9 percent rate suggests that about two-thirds of the applications he reviews result in a granted patent, provided the claims are well-supported. The 832 resolved cases establish a reliable baseline for predicting outcomes in Art Unit 3739.

The interview lift for this examiner is 18.3 percent. This positive lift indicates that interviews are a useful tool for applicants, providing a meaningful increase in the probability of allowance over the 63.9 percent baseline. Engaging in a dialogue with the examiner can help clarify technical points and resolve disagreements more efficiently than written correspondence alone. Practitioners should consider the 18.3 percent lift as a strong reason to schedule an interview during the prosecution process in Tech Center 3700.

The median days to allowance for his cases is 1465. This is a very long timeline, reflecting a slower prosecution cycle in Art Unit 3739. Applicants should factor this 1465-day median pendency into their long-term planning. Despite the long timeline, the 63.9 percent allowance rate and the 18.3 percent interview lift provide a clear and encouraging roadmap for successful patent prosecution. The 1465-day duration is a vital metric for managing expectations.
