What this shows Circa's Innovation Score is 37.5/100 (top 43% 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 Circa?

Each dot is one of Circa’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). Circa’s own 15.7 claims/patent is at or below the 17.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Circa's grants concentrate

Circa Scientific, Inc. is a focused PatentsView assignee: 3 CPC subclasses with 84.2% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2015. By volume, Circa sits between Champion Engine Technology, LLC and Con-Tech Manufacturing, Inc..

Circa's three-year grant acceleration

Circa Scientific, Inc. shows 7 grants in 2022–2024 against only 4 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.
