Portfolio overview

ESKI Inc. has been granted 12 US utility patents between 2016 and 2020, placing ESKI Inc. at rank #22,507 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 27.0 claims per patent with primary concentration in A63J (DEVICES FOR THEATRES, CIRCUSES, OR THE LIKE; CONJURING APPLIANCES OR THE LIKE). As a Foreign Corporation, ESKI Inc. is one of the more focused assignees in the PatentsView dataset. By volume, ESKI sits between Energy Absorption Systems, Inc. (12 patents, rank #22,503) and Etrog Systems Ltd. (12 patents, rank #22,511) - the closest US assignees by grant volume. The composite Innovation Score of 36.1/100 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 1 grants, compared with 11 in the 2015–2019 window, a -91% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. ESKI Inc.'s 27.0 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ESKI Inc. against peers pursuing similar technology classes.

How to use this portfolio

ESKI's 12 grants land it in the top 47% 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 - ESKI ranks #22,507 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in A63J - see who else leads that technology area. A63J 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.
