What this shows American's Innovation Score is 24.9/100 (16th percentile 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 American?
Each dot is one of American’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). American’s own 8.3 claims/patent is at or below the 15.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where American's grants concentrate
American Ceramic Technology is a focused PatentsView assignee: 3 CPC subclasses with 28.6% of grants classified under G21F (Protection Against X-radiation, Gamma Radiation, Corpuscular Radiation OR Particle BOMBARDMENT; Treating Radioactively Contaminated MATERIAL; Decontamination Arrangements Therefor). Peak complete grant year is 2015 (5 grants) versus a trough of 1 in 2017. By volume, American sits between Altus Intervention AS and Ameriprise Financial, Inc..
American's three-year grant acceleration
American Ceramic Technology shows 1 grants in 2022–2024 against only 0 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.
