What this shows Weir's Innovation Score is 47.5/100 (top 18% 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 15.3 claims/patent is ABOVE the 13.9 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 Minerals Australia Ltd. is a focused PatentsView assignee: 29 CPC subclasses with 55.6% of grants classified under F04D (Non-positive-displacement Pumps). Peak complete grant year is 2018 (10 grants) versus a trough of 1 in 2023. By volume, Weir sits between The Secretary of State for Defence and eYs3D Microelectronics, Co..

Weir's three-year grant acceleration

Weir Minerals Australia Ltd. shows 9 grants in 2022–2024 against only 11 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.
