What this shows Advanced's Innovation Score is 38.2/100 (top 41% 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 Advanced?

Each dot is one of Advanced’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). Advanced’s own 22.8 claims/patent is ABOVE the 13.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Advanced's grants concentrate

Advanced Ceramic Fibers, LLC is a focused PatentsView assignee: 17 CPC subclasses with 100% of grants classified under C04B (Lime, MAGNESIA; SLAG; CEMENTS; Compositions Thereof, e.g. Mortars, Concrete OR Like Building MATERIALS; Artificial Stone ; Ceramics ; REFRACTORIES; Treatment OF Natural Stone). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2017. By volume, Advanced sits between Adaptive Sensory Technology, Inc. and Aerogroup International Holdings LLC.

Advanced's three-year grant acceleration

Advanced Ceramic Fibers, LLC shows 1 grants in 2022–2024 against only 4 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.
