Analysis

Katherine Peebles operates in Tech Center 1600 and Art Unit 1614, where she has handled 515 resolved cases. Her allowance rate is 35.5%, which indicates a rigorous examination process. The median days to allowance for successful applications is 1177. A significant feature of her profile is the interview lift of 48.6%.

This high lift suggests that conducting an interview is a very effective strategy for increasing the probability of an allowance. Practitioners should strongly consider requesting an interview to address any rejections or objections. With 515 resolved cases, the data provides a clear indication of the examiner's tendencies. The combination of a 35.5% allowance rate and a 1177-day timeline suggests that securing a patent in Art Unit 1614 under this examiner requires a strong technical case. However, the 48.6% interview lift highlights that direct communication is a powerful tool for advancing prosecution toward a favorable outcome. These 515 resolutions provide a robust data set for strategic planning.
