Portfolio overview

1304342 Alberta Ltd. has been granted 21 US utility patents between 2015 and 2025, placing 1304342 Alberta Ltd. at rank #13,815 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.6 claims per patent with primary concentration in F25J (LIQUEFACTION, SOLIDIFICATION OR SEPARATION OF GASES OR GASEOUS ; OR LIQUEFIED GASEOUS; MIXTURES BY PRESSURE AND COLD TREATMENT ; OR BY BRINGING THEM INTO THE SUPERCRITICAL STATE). As a Foreign Corporation, 1304342 Alberta Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, 1304342 sits between Esilicon Corporation (22 patents, rank #13,811) and 6 River Systems, Llc (21 patents, rank #13,819) - the closest US assignees by grant volume. The composite Innovation Score of 36.5/100 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 15 grants, compared with 6 in the 2015–2019 window, a +150% 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. 1304342 Alberta Ltd.'s 12.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark 1304342 Alberta Ltd. against peers pursuing similar technology classes.

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.
