What this shows Ballard's Innovation Score is 43.7/100 (top 27% 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 Ballard?

Each dot is one of Ballard’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). Ballard’s own 15.9 claims/patent is ABOVE the 12.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ballard's grants concentrate

Ballard Power Systems Inc. is a focused PatentsView assignee: 14 CPC subclasses with 100% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2015 (8 grants) versus a trough of 1 in 2017. By volume, Ballard sits between Aurora Office Equipment Co., Ltd. Shanghai and Bharat Biotech International Limited.

Ballard's three-year grant acceleration

Ballard Power Systems Inc. shows 6 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.
