Analysis

SINGH, DALZID E is assigned to Tech Center 2800 and Art Unit 2613. The profile covers 899 resolved cases, with a 90.9% allowance rate and a 6.8% interview lift. The allowance rate indicates a highly favorable recorded outcome pattern, while the interview figure suggests limited additional effect from interviews. Applicants may therefore prioritize precise claim drafting, efficient written responses, and focused amendments, using interviews when they can resolve a specific point of interpretation.

The median time to allowance is 780 days. Telefonaktiebolaget LM Ericsson, Nippon Telegraph and Telephone Corporation, and Microsoft Technology Licensing, LLC are the listed leading companies. The leading firms are Baker Botts L.L.P., BRAKE HUGHES BELLERMANN LLP, and DUNLAP CODDING, P.C. The profile supports streamlined prosecution, but counsel should continue to document distinctions carefully and monitor timing. A favorable allowance pattern does not eliminate the need for application-specific analysis.
