Statistics are computed by Boundly Prosecution Intel from USPTO Patent Center (formerly PAIR) file wrappers for filing years 2021–2026, refreshed regularly. Allowance rate (sometimes called grant rate) is the share of disposed applications that issued as patents. Office actions here are non-final and final rejections, so restriction requirements and allowances are not counted. USPTO benchmarks are weighted to each examiner's mix of filing years, and art-unit benchmarks to the art units and filing years of the examiner's own applications, so they compare like for like. The difficulty percentile ranks examiners, each counted once, so it can point the other way from the USPTO average, which counts applications. See how each number is computed. The year-by-year interview and RCE tables show up to four recent filing years, leaving out the newest one and any year with fewer than ten applications or five decided applications on either side. Historical data is provided for informational purposes only. Past examiner behavior does not guarantee future outcomes, and nothing here is legal advice or a substitute for advice from a licensed patent attorney or agent. Are you Dzung Tran, or see an error?
