Does more volume mean deeper claims for KBK?

Each dot is one of KBK’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). KBK’s own 12.0 claims/patent is ABOVE the 10.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where KBK's grants concentrate

KBK Industries, LLC is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under B01D (Separation). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2015. By volume, KBK sits between Kanefusa Kabushiki Kaisha and Kidde Graviner Limited.

KBK's three-year grant acceleration

KBK Industries, LLC shows 1 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.
