Does more volume mean deeper claims for Hammelmann?

Each dot is one of Hammelmann’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). Hammelmann’s own 15.2 claims/patent is ABOVE the 10.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hammelmann's grants concentrate

Hammelmann GmbH is a focused PatentsView assignee: 7 CPC subclasses with 40% of grants classified under F16J (Pistons ; CYLINDERS; Sealings). By volume, Hammelmann sits between Halilit export 1974 Ltd. and Hangzhou Adamerck Pharmlabs, Inc..

Hammelmann's three-year grant acceleration

Hammelmann GmbH shows 2 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.
