Does more volume mean deeper claims for Kaydon?

Each dot is one of Kaydon’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). Kaydon’s own 15.3 claims/patent is ABOVE the 12.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kaydon's grants concentrate

Kaydon Ring & Seal, Inc. is a focused PatentsView assignee: 10 CPC subclasses with 82.4% of grants classified under F16J (Pistons ; CYLINDERS; Sealings). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2015. By volume, Kaydon sits between Justrite Manufacturing Company, L.L.C. and Kitaru Innovations Inc..

Kaydon's three-year grant acceleration

Kaydon Ring & Seal, Inc. shows 2 grants in 2022–2024 against only 10 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.
