What this shows Precision's Innovation Score is 39.3/100 (top 39% 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 Precision?

Each dot is one of Precision’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). Precision’s own 25.9 claims/patent is ABOVE the 11.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Precision's grants concentrate

Precision Rail and Mfg., Inc. is a focused PatentsView assignee: 8 CPC subclasses with 50% of grants classified under B61K (Auxiliary Equipment Specially Adapted FOR Railways, NOT Otherwise Provided FOR). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2016. By volume, Precision sits between Power Probe Group, Inc. and Pressio Inc..

Precision's three-year grant acceleration

Precision Rail and Mfg., Inc. shows 3 grants in 2022–2024 against only 3 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.
