What this shows Anest's Innovation Score is 30.9/100 (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 Anest?

Each dot is one of Anest’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). Anest’s own 4.5 claims/patent is at or below the 15.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Anest's grants concentrate

Anest Iwata Corporation is a focused PatentsView assignee: 16 CPC subclasses with 34.2% of grants classified under F04C (Rotary-piston, OR Oscillating-piston, Positive-displacement Machines FOR Liquids ; Rotary-piston, OR Oscillating-piston, Positive-displacement Pumps). Peak complete grant year is 2016 (15 grants) versus a trough of 1 in 2020. By volume, Anest sits between Atop S.p.A. and Banner Life Sciences LLC.

Anest's three-year grant acceleration

Anest Iwata Corporation shows 1 grants in 2022–2024 against only 5 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.
