Does more volume mean deeper claims for Herrenknecht?

Each dot is one of Herrenknecht’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). Herrenknecht’s own 14.2 claims/patent is ABOVE the 12.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Herrenknecht's grants concentrate

Herrenknecht Aktiengesellschaft is a focused PatentsView assignee: 17 CPC subclasses with 76.7% of grants classified under E21D (SHAFTS; TUNNELS; GALLERIES; Large Underground Chambers). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2017. By volume, Herrenknecht sits between Global Life Sciences Solutions Operations UK Limited and Hubspot, Inc..

Herrenknecht's three-year grant acceleration

Herrenknecht Aktiengesellschaft shows 10 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.
