Does more volume mean deeper claims for Leifeld?
Each dot is one of Leifeld’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). Leifeld’s own 12.7 claims/patent is ABOVE the 10.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Leifeld's grants concentrate
Leifeld Metal Spinning AG is a focused PatentsView assignee: 4 CPC subclasses with 88.9% of grants classified under B21D (Working OR Processing OF Sheet Metal OR Metal Tubes, Rods OR Profiles Without Essentially Removing MATERIAL; Punching Metal). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2015. By volume, Leifeld sits between Laydon Composites Ltd. and Lenze Swiss AG.
Leifeld's three-year grant acceleration
Leifeld Metal Spinning AG shows 3 grants in 2022–2024 against only 3 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.
