What this shows Heidelbergcement's Innovation Score is 37.3/100 (top 44% 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 Heidelbergcement?

Each dot is one of Heidelbergcement’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). Heidelbergcement’s own 26.1 claims/patent is ABOVE the 16.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Heidelbergcement's grants concentrate

Heidelbergcement AG is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under C04B (Lime, MAGNESIA; SLAG; CEMENTS; Compositions Thereof, e.g. Mortars, Concrete OR Like Building MATERIALS; Artificial Stone ; Ceramics ; REFRACTORIES; Treatment OF Natural Stone). Peak complete grant year is 2015 (5 grants) versus a trough of 1 in 2018. By volume, Heidelbergcement sits between Hazen Paper Company and Highspot, Inc..

Heidelbergcement's three-year grant acceleration

Heidelbergcement AG shows 1 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.
