What this shows Saf-t-glo's Innovation Score is 41.9/100 (top 32% 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 Saf-t-glo?

Each dot is one of Saf-t-glo’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). Saf-t-glo’s own 16.3 claims/patent is ABOVE the 12.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Saf-t-glo's grants concentrate

Saf-t-glo Limited is a focused PatentsView assignee: 20 CPC subclasses with 86.7% of grants classified under B64D (Equipment FOR Fitting IN OR TO AIRCRAFT; Flight SUITS; PARACHUTES; Arrangement OR Mounting OF Power Plants OR Propulsion Transmissions IN Aircraft). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2016. By volume, Saf-t-glo sits between Rhein Chemie Rheinau GmbH and Sankei Giken Kogyo Co., Ltd..

Saf-t-glo's three-year grant acceleration

Saf-t-glo Limited 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.
