Does more volume mean deeper claims for Langenstein?

Each dot is one of Langenstein’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). Langenstein’s own 19.0 claims/patent is ABOVE the 11.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Langenstein's grants concentrate

Langenstein & Schemann GMBH is a focused PatentsView assignee: 8 CPC subclasses with 88.9% of grants classified under B21J (FORGING; HAMMERING; Pressing METAL; RIVETING; Forge Furnaces). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2015. By volume, Langenstein sits between Laboratoires M&L and LC Technologies, Inc..

Langenstein's three-year grant acceleration

Langenstein & Schemann GMBH shows 1 grants in 2022–2024 against only 4 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.
