The verdict
Cardinal holds 55 US patents across 32 technology areas, rank #6,125 of 50,000 tracked assignees.
Cardinal IG Company has been granted 55 US utility patents between 2015 and 2025, placing Cardinal IG Company at rank #6,125 across all assignees tracked by PlainPatent. This portfolio spans 32 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.1 claims per patent with primary concentration in E06B (FIXED OR MOVABLE CLOSURES FOR OPENINGS IN BUILDINGS, VEHICLES, FENCES OR LIKE ENCLOSURES IN GENERAL, e.g. DOORS, WINDOWS, BLINDS, GATES). As a US Corporation, Cardinal IG Company is one of the more focused assignees in the PatentsView dataset. By volume, Cardinal sits between China Tobacco Hunan Industrial Co., Ltd. (55 patents, rank #6,121) and Cold Spring Harbor Laboratory (55 patents, rank #6,129) - the closest US assignees by grant volume. The composite Innovation Score of 53.0/100 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 36 grants, compared with 19 in the 2015–2019 window, a +89% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Cardinal IG Company's 20.1 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 32 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Cardinal IG Company against peers pursuing similar technology classes.

How to use this portfolio
Cardinal's 55 grants land it in the top 9% 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.
