What this shows Chemrus's Innovation Score is 25.3/100 (17th 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 Chemrus?

Each dot is one of Chemrus’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). Chemrus’s own 9.0 claims/patent is at or below the 16.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chemrus's grants concentrate

Chemrus, Inc. is a focused PatentsView assignee: 4 CPC subclasses with 60% of grants classified under B01L (Chemical OR Physical Laboratory Apparatus FOR General USE). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, Chemrus sits between Chelak Medical Solutions Inc and Chiayo Electronics Co., Ltd..

Chemrus's three-year grant acceleration

Chemrus, Inc. shows 1 grants in 2022–2024 against only 1 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.
