Examiner: YEUNG, MATTHEW

Analysis

Matthew Yeung serves in Tech Center 2800, Art Unit 2621. He has resolved 525 cases with an allowance rate of 74.3 percent. This performance demonstrates a consistent track record of granting patents within his assigned technical field. The 74.3 percent allowance rate suggests that nearly three-quarters of applications are eventually allowed under his review.

The median duration to reach an allowance is 947 days. An interview lift of 9.2 percent indicates that direct communication with the examiner provides a moderate benefit to the applicant. These figures suggest a standard prosecution timeline with a strong probability of eventual allowance. Practitioners should consider the 9.2 percent lift when deciding whether to interview, as it offers a measurable improvement over the 74.3 percent baseline. The 947-day median pendency is consistent with efficient prosecution in Tech Center 2800. With 525 resolved cases, the examiner's data provides a reliable outlook for future applications. Direct engagement can be a useful supplement to written responses.
