What this shows Appalachian's Innovation Score is 37.3/100 (top 44% 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 Appalachian?

Each dot is one of Appalachian’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). Appalachian’s own 19.2 claims/patent is ABOVE the 15.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Appalachian's grants concentrate

Appalachian Lighting Systems, Inc. is a focused PatentsView assignee: 10 CPC subclasses with 66.7% of grants classified under F21V (Functional Features OR Details OF Lighting Devices OR Systems THEREOF; Structural Combinations OF Lighting Devices With Other Articles, NOT Otherwise Provided FOR). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, Appalachian sits between Ansorg GmbH and Aquanova AG.

Appalachian's three-year grant acceleration

Appalachian Lighting Systems, Inc. shows 2 grants in 2022–2024 against only 2 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.
