Analysis

SIMPSON, LIXI CHOW works in Tech Center 2600 and Art Unit 2625. The profile records 867 resolved cases, a 74.0% allowance rate, and an 8.8% interview lift. The allowance rate is favorable in the recorded matters, while the interview figure indicates that interviews may have a limited measured effect. Applicants may therefore prioritize precise written responses and focused claim amendments, using interviews when a discrete interpretive issue would benefit from direct discussion.

The median time to allowance is 968 days. Samsung Electronics Co., Ltd., Apple Inc., and Canon Inc. are the listed leading companies. The leading firms are Amsel IP Law PLLC, Jefferson IP Law, LLP, and OLIFF PLC. The profile supports efficient prosecution with attention to claim clarity and prior art distinctions. Counsel should maintain a disciplined amendment record and monitor timing closely, because the favorable allowance pattern does not itself establish a short path to allowance.
