What this shows Doble's Innovation Score is 39.1/100 (top 39% 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 Doble?

Each dot is one of Doble’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). Doble’s own 19.1 claims/patent is ABOVE the 15.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Doble's grants concentrate

Doble Engineering Company is a focused PatentsView assignee: 10 CPC subclasses with 81.3% of grants classified under G01R (Measuring Electric VARIABLES; Measuring Magnetic Variables). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2018. By volume, Doble sits between Deutsches Institut für Lebensmitteltechnik e.V. and Dr. Fresh LLC.

Doble's three-year grant acceleration

Doble Engineering Company shows 5 grants in 2022–2024 against only 5 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.
