What this shows J.a.'s Innovation Score is 42.0/100 (top 32% 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 J.a.?

Each dot is one of J.a.’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). J.a.’s own 19.1 claims/patent is ABOVE the 11.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where J.a.'s grants concentrate

J.A. Woollam Co., Inc. is a focused PatentsView assignee: 18 CPC subclasses with 87.5% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2018 (13 grants) versus a trough of 1 in 2022. By volume, J.a. sits between Industrial Cooperation Foundation Chonbuk National University and Kyoto Prefectural Public University Corporation.

J.a.'s three-year grant acceleration

J.A. Woollam Co., Inc. shows 5 grants in 2022–2024 against only 16 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.
