What this shows Hedman's Innovation Score is 38.8/100 (top 40% 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 Hedman?

Each dot is one of Hedman’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). Hedman’s own 9.3 claims/patent is at or below the 15.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hedman's grants concentrate

Hedman Ericsson Patent AB is a focused PatentsView assignee: 7 CPC subclasses with 71.4% of grants classified under F02D (Controlling Combustion Engines). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2023. By volume, Hedman sits between HeartHero, Inc. and Heinz Kurz GmbH Medizintechnik.

Hedman's three-year grant acceleration

Hedman Ericsson Patent AB shows 5 grants in 2022–2024 against only 2 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.
