Portfolio overview

Phase IV Engineering Inc. has been granted 7 US utility patents between 2018 and 2024, placing Phase IV Engineering Inc. at rank #37,004 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 21.0 claims per patent with primary concentration in H04Q (SELECTING). As a US Corporation, Phase IV Engineering Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Phase sits between Pet's Best Life, L.l.c. (7 patents, rank #37,000) and Phokus Research Group, Llc (7 patents, rank #37,008) - the closest US assignees by grant volume. The composite Innovation Score of 51.5/100 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 6 grants, compared with 1 in the 2015–2019 window, a +500% 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. Phase IV Engineering Inc.'s 21.0 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Phase IV Engineering Inc. against peers pursuing similar technology classes.

How to use this portfolio

Phase's 7 grants land it in the top 11% 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 - Phase ranks #37,004 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H04Q - see who else leads that technology area. H04Q 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.
