What this shows Halkey-roberts's Innovation Score is 29.8/100 (32nd 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 Halkey-roberts?

Each dot is one of Halkey-roberts’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). Halkey-roberts’s own 14.3 claims/patent is at or below the 14.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Halkey-roberts's grants concentrate

Halkey-Roberts Corporation is a focused PatentsView assignee: 9 CPC subclasses with 43.8% of grants classified under A61M (Devices FOR Introducing Media Into, OR Onto, THE Body ; Devices FOR Transducing Body Media OR FOR Taking Media From THE Body ; Devices FOR Producing OR Ending Sleep OR Stupor). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2016. By volume, Halkey-roberts sits between Huizhou Dayawan Ever Bright Electronic Industry Co and Heidelberg Pharma Research GmbH.

Halkey-roberts's three-year grant acceleration

Halkey-Roberts Corporation shows 1 grants in 2022–2024 against only 8 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.
