What this shows Shibaura's Innovation Score is 59.3/100 (top 4% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Shibaura?

Each dot is one of Shibaura’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). Shibaura’s own 8.8 claims/patent is at or below the 18.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Shibaura's grants concentrate

Shibaura Machine Co., Ltd. is a focused PatentsView assignee: 33 CPC subclasses with 78.4% of grants classified under B29C (Shaping OR Joining OF PLASTICS; Shaping OF Material IN A Plastic State, NOT Otherwise Provided FOR; After-treatment OF THE Shaped Products, e.g. Repairing). Peak complete grant year is 2023 (14 grants) versus a trough of 2 in 2020. By volume, Shibaura sits between Rafael Advanced Defense Systems Ltd. and Technoprobe S.P.A..

Shibaura's three-year grant acceleration

Shibaura Machine Co., Ltd. shows 33 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.
