The verdict
Alfdex holds 10 US patents across 3 technology areas, rank #25,665 of 50,000 tracked assignees.
Alfdex AB has been granted 10 US utility patents between 2016 and 2025, placing Alfdex AB at rank #25,665 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.1 claims per patent with primary concentration in F01M (LUBRICATING OF MACHINES OR ENGINES IN GENERAL; LUBRICATING INTERNAL COMBUSTION ENGINES; CRANKCASE VENTILATING). As a Foreign Corporation, Alfdex AB is one of the more focused assignees in the PatentsView dataset. By volume, Alfdex sits between Akwel (10 patents, rank #25,661) and Allen-vanguard Corporation (10 patents, rank #25,669) - the closest US assignees by grant volume. The composite Innovation Score of 30.7/100 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 8 grants, compared with 2 in the 2015–2019 window, a +300% 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. Alfdex AB's 16.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Alfdex AB against peers pursuing similar technology classes.

How to use this portfolio
Alfdex's 10 grants land it in the top 65% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
