Analysis

SINGH, AVIRAJ DONGSOOK works in Tech Center 4100 and Art Unit 3645. The profile contains 1 resolved case, with a 0.0% allowance rate and a 0.0% interview lift. Because the recorded docket is extremely limited, these figures provide very little basis for predicting future matters. The available record does not show an allowance or an interview-associated improvement, so practitioners should rely on the application’s specific facts, the cited art, and the examiner’s current reasoning.

The median time to allowance is 1302 days. The listed companies are Shenzhen Yinwang Intelligent Technology Co., Ltd., Canon Inc., and Panasonic Holdings Corporation. The leading firms are FISH & RICHARDSON P.C. (TC), Chiesa Shahinian & Giantomasi PC, and HARNESS, DICKEY & PIERCE, P.L.C. Counsel should treat this profile as an early and incomplete signal, prepare a thorough written record, and evaluate any interview only in light of the individual prosecution issues.
