Portfolio overview

Westport FUEL Systems Canada Inc. has been granted 9 US utility patents between 2021 and 2023, placing Westport FUEL Systems Canada Inc. at rank #30,564 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 21.0 claims per patent with primary concentration in Y02T (CLIMATE CHANGE MITIGATION TECHNOLOGIES RELATED TO TRANSPORTATION). As a Foreign Corporation, Westport FUEL Systems Canada Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Westport sits between Weiss Gmbh (9 patents, rank #30,560) and Whitesource Ltd. (9 patents, rank #30,568) - the closest US assignees by grant volume. The composite Innovation Score of 40.6/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Historical data spans 2021 through 2023, with 9 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Westport FUEL Systems Canada Inc.'s 21.0 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Westport FUEL Systems Canada Inc. against peers pursuing similar technology classes.

How to use this portfolio

Westport's 9 grants land it in the top 35% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Westport ranks #30,564 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in Y02T - see who else leads that technology area. Y02T leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
