What this shows Drive's Innovation Score is 21.3/100 (8th 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 Drive?

Each dot is one of Drive’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). Drive’s own 2.3 claims/patent is at or below the 11.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Drive's grants concentrate

Drive Cjsc is a focused PatentsView assignee: 5 CPC subclasses with 77.8% of grants classified under H02M (Apparatus FOR Conversion Between AC AND AC, Between AC AND DC, OR Between DC AND DC, AND FOR USE With Mains OR Similar Power Supply SYSTEMS; Conversion OF DC OR AC Input Power Into Surge Output POWER;). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2018. By volume, Drive sits between Doubleday Acquisitions, LLC and DuraPlas, LP.

Drive's three-year grant acceleration

Drive Cjsc shows 3 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.
