Does more volume mean deeper claims for Ubukata?
Each dot is one of Ubukata’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). Ubukata’s own 8.3 claims/patent is at or below the 10.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Ubukata's grants concentrate
Ubukata Industries Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 75% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2019. By volume, Ubukata sits between U-tec Group Inc. and Uledger, Inc..
Ubukata's three-year grant acceleration
Ubukata Industries Co., Ltd. shows 2 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.
