Portfolio overview

H55 SA has been granted 17 US utility patents between 2018 and 2025, placing H55 SA at rank #16,845 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 23.5 claims per patent with primary concentration in Y02T (CLIMATE CHANGE MITIGATION TECHNOLOGIES RELATED TO TRANSPORTATION). As a Foreign Corporation, H55 SA is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 41.9/100 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. Between 2020 and 2025 the company received 14 grants, compared with 3 in the 2015–2019 window, a +367% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. H55 SA's 23.5 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark H55 SA against peers pursuing similar technology classes.

How to use this portfolio

H55's 17 grants land it in the top 32% 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 - H55 ranks #16,845 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.
