What this shows Rotork's Innovation Score is 54.0/100 (top 8% 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 Rotork?

Each dot is one of Rotork’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). Rotork’s own 22.8 claims/patent is ABOVE the 14.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Rotork's grants concentrate

Rotork Controls Limited is a focused PatentsView assignee: 13 CPC subclasses with 62.5% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2015. By volume, Rotork sits between Rokit Healthcare Inc. and Ruskin Company.

Rotork's three-year grant acceleration

Rotork Controls Limited shows 4 grants in 2022–2024 against only 0 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.
