What this shows Sunamp's Innovation Score is 35.3/100 (top 50% 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 Sunamp?

Each dot is one of Sunamp’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). Sunamp’s own 14.5 claims/patent is at or below the 15.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sunamp's grants concentrate

Sunamp Limited is a focused PatentsView assignee: 10 CPC subclasses with 86.7% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2020. By volume, Sunamp sits between Streater, LLC and Suzhou Shengkang Plastic Electric Co., Ltd..

Sunamp's three-year grant acceleration

Sunamp Limited shows 7 grants in 2022–2024 against only 8 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.
