Does more volume mean deeper claims for BK?

Each dot is one of BK’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). BK’s own 2.6 claims/patent is at or below the 16.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where BK's grants concentrate

BK Resources, Inc. is a focused PatentsView assignee: 1 CPC subclasses with 14.3% of grants classified under E03C (Domestic Plumbing Installations FOR Fresh Water OR Waste Water ; Sinks). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2018. By volume, BK sits between Bitswave Inc. and Blink Technologies Inc..

BK's three-year grant acceleration

BK Resources, Inc. shows 5 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.
