What this shows Foamtec's Innovation Score is 36.6/100 (top 46% 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 Foamtec?

Each dot is one of Foamtec’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). Foamtec’s own 13.4 claims/patent is at or below the 13.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Foamtec's grants concentrate

Foamtec International Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 50% of grants classified under B08B (Cleaning IN GENERAL; Prevention OF Fouling IN General). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2016. By volume, Foamtec sits between Fianium Ltd. and Foseco International Limited.

Foamtec's three-year grant acceleration

Foamtec International Co., Ltd. shows 6 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.
