Does more volume mean deeper claims for KUK?

Each dot is one of KUK’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). KUK’s own 11.6 claims/patent is ABOVE the 9.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where KUK's grants concentrate

KUK IL Inntot Co. , Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under F16J (Pistons ; CYLINDERS; Sealings). By volume, KUK sits between Kubota Manufacturing Corporation and Kumonos Corporation.

KUK's three-year grant acceleration

KUK IL Inntot Co. , Ltd. shows 1 grants in 2022–2024 against only 1 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.
