What this shows SL's Innovation Score is 46.8/100 (top 20% 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 SL?

Each dot is one of SL’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). SL’s own 12.6 claims/patent is at or below the 18.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where SL's grants concentrate

SL Mirrortech Corporation is a focused PatentsView assignee: 9 CPC subclasses with 63.6% of grants classified under B60R (Vehicles, Vehicle Fittings, OR Vehicle Parts, NOT Otherwise Provided FOR). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2017. By volume, SL sits between Sinopsys Surgical, Inc. and Snaps Solutions, LLC.

SL's three-year grant acceleration

SL Mirrortech Corporation shows 6 grants in 2022–2024 against only 1 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.
