Portfolio overview

Largo Clean Energy Corp. has been granted 5 US utility patents between 2021 and 2024, placing Largo Clean Energy Corp. at rank #48,405 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.4 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a US Corporation, Largo Clean Energy Corp. is one of the more focused assignees in the PatentsView dataset. By volume, Largo sits between Langeman Manufacturing Limited (5 patents, rank #48,401) and Lateral Reality Kft. (5 patents, rank #48,409) - the closest US assignees by grant volume. The composite Innovation Score of 46.6/100 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 2024, with 5 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The US 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. Largo Clean Energy Corp.'s 16.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Largo Clean Energy Corp. against peers pursuing similar technology classes.

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.
