Portfolio overview

Hydro-québec has been granted 61 US utility patents between 2015 and 2025, placing Hydro-québec at #5,595 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 60 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.2 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Hydro-québec is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Hydro-québec sits between Garden Genetics Llc (61 patents, rank #5,588) and Innovaplant Zierpflanzen Gmbh + Co. KG (61 patents, rank #5,596) - the closest US assignees by grant volume. The composite Innovation Score of 57.8/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 42 grants, compared with 10 in the 2015–2019 window, a +320% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Hydro-québec's 20.2 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 60 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
