What this shows Weir's Innovation Score is 30.1/100 (33rd percentile 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 Weir?

Each dot is one of Weir’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). Weir’s own 16.7 claims/patent is ABOVE the 10.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Weir's grants concentrate

Weir Canada, Inc. is a focused PatentsView assignee: 11 CPC subclasses with 50% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2018. By volume, Weir sits between Webo Werkzeugbau Oberschwaben GMBH and Wexenergy Innovations LLC.

Weir's three-year grant acceleration

Weir Canada, Inc. shows 1 grants in 2022–2024 against only 4 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.
