What this shows Chemtron's Innovation Score is 46.2/100 (top 21% 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 Chemtron?

Each dot is one of Chemtron’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). Chemtron’s own 21.1 claims/patent is ABOVE the 17.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chemtron's grants concentrate

Chemtron Research LLC is a focused PatentsView assignee: 18 CPC subclasses with 43.6% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2017 (10 grants) versus a trough of 1 in 2015. By volume, Chemtron sits between Capbran Holdings, LLC and Doheny EYE Institute.

Chemtron's three-year grant acceleration

Chemtron Research LLC shows 7 grants in 2022–2024 against only 8 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.
