Portfolio overview

Kardium Inc. has been granted 146 US utility patents between 2015 and 2025, placing Kardium Inc. at rank #2,661 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 31.0 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a Foreign Corporation, Kardium Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Kardium sits between FMC Corporation (146 patents, rank #2,657) and Roquette Freres (146 patents, rank #2,665) - the closest US assignees by grant volume. The composite Innovation Score of 48.3/100 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 85 grants, compared with 61 in the 2015–2019 window, a +39% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Kardium Inc.'s 31.0 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kardium Inc. 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.
