Each dot is one of Sengoku’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). Sengoku’s own 1.0 claims/patent is at or below the 18.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sengoku's grants concentrate

Sengoku Works, Ltd. is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2019. By volume, Sengoku sits between Secure Systems Innovation Corporation and Sentinel Oncology Limited.

Sengoku's three-year grant acceleration

Sengoku Works, Ltd. shows 5 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.
