What this shows Knoxville's Innovation Score is 47.3/100 (top 19% 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 Knoxville?

Each dot is one of Knoxville’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). Knoxville’s own 12.4 claims/patent is at or below the 17.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Knoxville's grants concentrate

Knoxville Locomotive Works, Inc. is a focused PatentsView assignee: 12 CPC subclasses with 75% of grants classified under B61C (LOCOMOTIVES; Motor Railcars). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2022. By volume, Knoxville sits between Kilburn Live, LLC and Koning Corporation.

Knoxville's three-year grant acceleration

Knoxville Locomotive Works, Inc. shows 7 grants in 2022–2024 against only 0 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.
