What this shows Astec's Innovation Score is 45.6/100 (top 23% 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 Astec?

Each dot is one of Astec’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). Astec’s own 15.2 claims/patent is ABOVE the 14.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Astec's grants concentrate

Astec Co., Ltd. is a focused PatentsView assignee: 33 CPC subclasses with 45.5% of grants classified under E01C (Construction OF, OR Surfaces FOR, Roads, Sports Grounds, OR THE LIKE; Machines OR Auxiliary Tools FOR Construction OR Repair). Peak complete grant year is 2017 (5 grants) versus a trough of 1 in 2018. By volume, Astec sits between Amerlux, LLC and Acorns Grow Incorporated.

Astec's three-year grant acceleration

Astec Co., Ltd. shows 4 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.
