Analysis

HUHN, RICHARD A is assigned to Tech Center 1700 and Art Unit 1754. Across 909 resolved cases, the allowance rate is 67.1%, the interview lift is 5.7%, and the median time to allowance is 1084 days. The substantial record provides a useful planning base, while the limited interview lift suggests that written responses may be especially important.

Daikin Industries Ltd., LG Chem Ltd., and Canon Inc. are the listed companies. SUGHRUE MION, PLLC, Abel Schillinger, LLP, and AMSTER, ROTHSTEIN & EBENSTEIN LLP are the listed firms. Practitioners should emphasize precise prior-art distinctions and use interviews selectively when a written response alone may leave ambiguity.
