What this shows Fosbel's Innovation Score is 34.0/100 (46th percentile 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 Fosbel?

Each dot is one of Fosbel’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). Fosbel’s own 8.2 claims/patent is at or below the 16.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Fosbel's grants concentrate

Fosbel, Inc. is a focused PatentsView assignee: 17 CPC subclasses with 53.8% of grants classified under F27D (Details OR Accessories OF Furnaces, Kilns, Ovens OR Retorts, IN SO FAR AS They ARE OF Kinds Occurring IN More Than ONE Kind OF Furnace). Peak complete grant year is 2019 (8 grants) versus a trough of 1 in 2017. By volume, Fosbel sits between Extremity Medical, LLC and Frito-Lay Trading Company GmbH.

Fosbel's three-year grant acceleration

Fosbel, Inc. shows 6 grants in 2022–2024 against only 13 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.
