Does more volume mean deeper claims for NJS?
Each dot is one of NJS’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). NJS’s own 10.8 claims/patent is at or below the 10.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where NJS's grants concentrate
NJS Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 60% of grants classified under E03F (SEWERS; Cesspools). By volume, NJS sits between Nippon Steel SG Wire Co., Ltd. and No-bull Enterprises LLC.
NJS's three-year grant acceleration
NJS Co., Ltd. shows 3 grants in 2022–2024 against only 0 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.
