Analysis

Quynh Dao Le is an examiner in Art Unit 3781, operating within Tech Center 3700. The data for this examiner includes 46 resolved cases, providing a focused look at their prosecution tendencies. The current allowance rate is 34.8 percent, which suggests a rigorous examination environment where less than half of the applications reach issuance. Practitioners should note the interview lift of 10.1 percent, which indicates that personal communication with the examiner provides a measurable benefit in securing an allowance.

The median days to allowance for this examiner is 1281, representing a relatively long prosecution timeline of over three and a half years. This 1281-day figure is a critical metric for applicants to consider when planning their patent strategy and budgeting for long-term prosecution. The 34.8 percent allowance rate, coupled with the 10.1 percent lift, suggests that while the path to allowance is challenging, interviews remain a viable tool for advancing a case. With 46 resolved cases, the examiner's patterns are established but may still evolve. Practitioners should prepare for a detailed and potentially extended examination process in Art Unit 3781. The 1281-day median pendency remains the primary benchmark for timeline expectations.
