Portfolio overview
ATOMIC ENERGY OF CANADA LIMITED has been granted 39 US utility patents between 2015 and 2022, placing ATOMIC ENERGY OF CANADA LIMITED at rank #8,156 across all assignees tracked by PlainPatent. This portfolio spans 26 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.6 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, ATOMIC ENERGY OF CANADA LIMITED is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 44.0/100 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 13 grants, compared with 26 in the 2015–2019 window — a -50% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. ATOMIC ENERGY OF CANADA LIMITED's 19.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 26 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ATOMIC ENERGY OF CANADA LIMITED against peers pursuing similar technology classes.
