What this shows S.a.'s Innovation Score is 49.4/100 (top 15% 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 S.a.?

Each dot is one of S.a.’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). S.a.’s own 24.2 claims/patent is ABOVE the 12.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where S.a.'s grants concentrate

S.A. Armstrong Limited is a focused PatentsView assignee: 15 CPC subclasses with 60% of grants classified under F04D (Non-positive-displacement Pumps). Peak complete grant year is 2023 (7 grants) versus a trough of 1 in 2018. By volume, S.a. sits between Recensmedical, Inc. and Sennheiser Communications A/S.

S.a.'s three-year grant acceleration

S.A. Armstrong Limited shows 14 grants in 2022–2024 against only 10 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.
