Portfolio overview

SK keyfoundry Inc. has been granted 41 US utility patents between 2024 and 2025, placing SK keyfoundry Inc. at rank #7,924 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.8 claims per patent with primary concentration in H10D (INORGANIC ELECTRIC SEMICONDUCTOR DEVICES). As a Foreign Corporation, SK keyfoundry Inc. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 55.2/100 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 2024 through 2025, with 41 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. SK keyfoundry Inc.'s 15.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SK keyfoundry Inc. against peers pursuing similar technology classes.

How to use this portfolio

SK's 41 grants land it in the top 7% by Innovation Score — but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance — SK ranks #7,924 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H10D — see who else leads that technology area. H10D leaders
  • 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.
