Portfolio overview

Hill Phoenix, Inc. has been granted 92 US utility patents between 2015 and 2025, placing Hill Phoenix, Inc. at rank #3,919 across all assignees tracked by PlainPatent. This portfolio spans 31 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.5 claims per patent with primary concentration in F25B (REFRIGERATION MACHINES, PLANTS OR SYSTEMS; COMBINED HEATING AND REFRIGERATION SYSTEMS; HEAT PUMP SYSTEMS). As a US Corporation, Hill Phoenix, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Hill sits between Flsmidth A/s (92 patents, rank #3,915) and Innovelis, Inc. (92 patents, rank #3,923) - the closest US assignees by grant volume. The composite Innovation Score of 63.0/100 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 60 grants, compared with 32 in the 2015–2019 window, a +88% 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. Hill Phoenix, Inc.'s 19.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 31 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hill Phoenix, Inc. against peers pursuing similar technology classes.

How to use this portfolio

Hill's 92 grants land it in the top 2% 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 - Hill ranks #3,919 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in F25B - see who else leads that technology area. F25B 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.
