Analysis

Liza Tony Kanaan is an examiner in Tech Center 3600 and Art Unit 3626 with 128 resolved cases. The allowance rate is 23.4 percent, which is relatively low and indicates a challenging examination environment. Top companies include Oura Health Oy, Cityblock Health Inc., and Canon Inc., represented by firms like ARENTFOX SCHIFF LLP, DORSEY & WHITNEY LLP - Denver, and ALG Intellectual Property | IQVIA.

The median days to allowance is 1160, which is the typical timeframe for successful cases. However, the interview lift of 31.5 percent is a significant positive factor. This suggests that while the examiner is rigorous in written prosecution, they are open to persuasion and clarification through interviews, which can substantially increase the likelihood of an allowance. Practitioners should consider interviews as a primary strategy to overcome the low baseline allowance rate and move their applications toward a grant.
