What this shows U.s.'s Innovation Score is 38.3/100 (top 41% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for U.s.?

Each dot is one of U.s.’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). U.s.’s own 13.1 claims/patent is at or below the 14.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where U.s.'s grants concentrate

U.S. Environmental Protection Agency is a focused PatentsView assignee: 20 CPC subclasses with 64.3% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2023. By volume, U.s. sits between Tritana Intellectual Property Ltd. and Universitetet I TROMSØ—NORGES Arktiske Universitet.

U.s.'s three-year grant acceleration

U.S. Environmental Protection Agency shows 4 grants in 2022–2024 against only 5 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
