What this shows Controlrad's Innovation Score is 32.2/100 (40th 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 Controlrad?

Each dot is one of Controlrad’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). Controlrad’s own 15.6 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Controlrad's grants concentrate

Controlrad Systems, Inc. is a focused PatentsView assignee: 11 CPC subclasses with 83.3% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2021. By volume, Controlrad sits between Cnpc Engineering Technology R&D Company Limited and CTK Co., Ltd..

Controlrad's three-year grant acceleration

Controlrad Systems, Inc. shows 1 grants in 2022–2024 against only 7 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.
