What this shows Obayashi's Innovation Score is 35.8/100 (top 48% 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 Obayashi?

Each dot is one of Obayashi’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). Obayashi’s own 11.3 claims/patent is at or below the 11.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Obayashi's grants concentrate

Obayashi Corporation is a focused PatentsView assignee: 13 CPC subclasses with 33.3% of grants classified under G06T (Image Data Processing OR Generation, IN General). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2020. By volume, Obayashi sits between Nylok LLC and Ohki Co., Ltd..

Obayashi's three-year grant acceleration

Obayashi Corporation shows 5 grants in 2022–2024 against only 4 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.
