What this shows Alfa's Innovation Score is 30.8/100 (36th 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 Alfa?

Each dot is one of Alfa’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). Alfa’s own 17.2 claims/patent is ABOVE the 14.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Alfa's grants concentrate

Alfa Wassermann, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 80% of grants classified under B04B (Centrifuges). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2015. By volume, Alfa sits between Ajoho Enterprise Co., Ltd and Alken Inc..

Alfa's three-year grant acceleration

Alfa Wassermann, Inc. shows 1 grants in 2022–2024 against only 3 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.
