What this shows Premier's Innovation Score is 38.3/100 (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 Premier?

Each dot is one of Premier’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). Premier’s own 21.3 claims/patent is ABOVE the 16.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Premier's grants concentrate

Premier Magnesia, LLC is a focused PatentsView assignee: 8 CPC subclasses with 66.7% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2015. By volume, Premier sits between Portwell Inc. and Protrend Co., Ltd..

Premier's three-year grant acceleration

Premier Magnesia, LLC 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.
