What this shows United's Innovation Score is 48.6/100 (top 16% 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 United?

Each dot is one of United’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). United’s own 18.6 claims/patent is ABOVE the 12.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where United's grants concentrate

United States Steel Corporation is a focused PatentsView assignee: 19 CPC subclasses with 70.6% of grants classified under C21D (Modifying THE Physical Structure OF Ferrous METALS; General Devices FOR Heat Treatment OF Ferrous OR Non-ferrous Metals OR ALLOYS; Making Metal Malleable, e.g. BY Decarburisation OR Tempering). Peak complete grant year is 2023 (4 grants) versus a trough of 2 in 2019. By volume, United sits between UNIVERSITÉ DE LIÈGE and Utex Industries Inc..

United's three-year grant acceleration

United States Steel Corporation shows 9 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.
