This examiner grants 64% of resolved cases

Analysis

WALSH, DANIEL I is assigned to Tech Center 2800 and Art Unit 2876. His record includes 807 resolved cases, with a 64.4% allowance rate and a median of 1151 days to allowance. The data reflects a majority allowance outcome across a substantial docket, but the median timing indicates that applicants should plan for more than three years of prosecution before allowance.

The 12.4% interview lift indicates a positive, though more limited, association between interviews and allowance. The leading companies are Dynamics Inc., Linxens Holding, and International Business Machines Corporation. The leading firms are ARENTFOX SCHIFF LLP, Blueshift IP LLC, and Bridgeway IP Law Group, PLLC. Interviews appear useful as one component of prosecution strategy, but the moderate lift does not make them a substitute for strong written responses.
