Does more volume mean deeper claims for Furukawa?
Each dot is one of Furukawa’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). Furukawa’s own 11.9 claims/patent is at or below the 16.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Furukawa's grants concentrate
Furukawa Rock Drill Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 69.2% of grants classified under B25D (Percussive Tools). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2019. By volume, Furukawa sits between Fresh Health Inc. and General Test Systems Inc..
Furukawa's three-year grant acceleration
Furukawa Rock Drill Co., Ltd. shows 2 grants in 2022–2024 against only 6 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.
