Does more volume mean deeper claims for Westport?

Each dot is one of Westport’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). Westport’s own 21.0 claims/patent is ABOVE the 12.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Westport's grants concentrate

Westport Fuel Systems Canada Inc. is a focused PatentsView assignee: 11 CPC subclasses with 66.7% of grants classified under Y02T (Climate Change Mitigation Technologies Related TO Transportation). Peak complete grant year is 2021 (4 grants) versus a trough of 2 in 2023. By volume, Westport sits between Weiss GmbH and Whitesource Ltd..

Westport's three-year grant acceleration

Westport Fuel Systems Canada Inc. shows 5 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.
