Analysis

Kate Elizabeth Strachan is an examiner in Tech Center 3700, working within Art Unit 3781. She has managed 111 resolved cases to date. Her allowance rate stands at 47.7 percent, which indicates a rigorous approach to patentability that requires thorough documentation and clear claim sets from applicants. This 47.7 percent rate suggests that a specific portion of the applications she reviews reach a successful conclusion.

The data highlights a significant benefit to examiner interaction, as Strachan demonstrates an interview lift of 30.1 percent. This figure suggests that verbal communication is a powerful tool for overcoming rejections in her docket. Practitioners might find that discussing claim amendments or technical nuances directly with her can bridge gaps that written responses may not fully address. Utilizing the 30.1 percent lift could be a decisive factor in prosecution.
