The verdict
Phase holds 6 US patents across 1 technology areas, rank #42,235 of 50,000 tracked assignees.
Phase Change Software Llc has been granted 6 US utility patents between 2019 and 2023, placing Phase Change Software Llc at rank #42,235 across all assignees tracked by PlainPatent. This portfolio spans 1 distinct Cooperative Patent Classification (CPC) subclasses, averaging 26.5 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a US Corporation, Phase Change Software Llc is one of the more focused assignees in the PatentsView dataset. By volume, Phase sits between PGP Glass USA, Inc. (6 patents, rank #42,231) and Photonic Sensors & Algorithms, S.l. (6 patents, rank #42,239) - the closest US assignees by grant volume. The composite Innovation Score of 26.6/100 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 3 grants, compared with 3 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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 Change Software Llc's 26.5 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 1 subclass reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Phase Change Software Llc against peers pursuing similar technology classes.

How to use this portfolio
Phase's 6 grants land it in the top 79% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
