Does more volume mean deeper claims for BKT?
Each dot is one of BKT’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). BKT’s own 7.2 claims/patent is at or below the 17.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where BKT's grants concentrate
BKT Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 80% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2020. By volume, BKT sits between Bizmodeline Co., Ltd. and Blackpoint Tactical LLC.
BKT's three-year grant acceleration
BKT Co., Ltd. shows 3 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.
