What this shows Circor's Innovation Score is 37.2/100 (top 44% 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 Circor?

Each dot is one of Circor’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). Circor’s own 16.2 claims/patent is ABOVE the 11.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Circor's grants concentrate

Circor Pumps North America, LLC is a focused PatentsView assignee: 15 CPC subclasses with 66.7% of grants classified under F04C (Rotary-piston, OR Oscillating-piston, Positive-displacement Machines FOR Liquids ; Rotary-piston, OR Oscillating-piston, Positive-displacement Pumps). Peak complete grant year is 2019 (6 grants) versus a trough of 1 in 2018. By volume, Circor sits between Chirp Microsystems Inc. and Clevermade, LLC.

Circor's three-year grant acceleration

Circor Pumps North America, LLC shows 6 grants in 2022–2024 against only 11 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.
