Analysis

PROSSER, ALISSA J examines in Tech Center 1600 and Art Unit 1619. Her profile records 510 resolved cases, a 15.5% allowance rate, and a 1273-day median time to allowance. The interview lift is 11.2%, positive but limited relative to the challenges reflected in the allowance rate.

The leading companies are L'Oréal, SHISEIDO Company, Ltd., and The Procter & Gamble Company. The listed firms are BIRCH STEWART KOLASCH & BIRCH, LLP, FOLEY & LARDNER LLP, and Clark+Elbing LLP.

Practitioners should treat initial claim strategy, prior-art analysis, and fallback positions as central planning matters. Interviews may assist with a defined rejection, but the profile does not support relying on interviews alone to change outcomes. The median timing also favors early decisions about scope, continuation needs, and the cost of extended prosecution.
