The verdict
Powertree holds 6 US patents across 8 technology areas, rank #42,270 of 50,000 tracked assignees.
Powertree Services, Inc. has been granted 6 US utility patents between 2015 and 2024, placing Powertree Services, Inc. at rank #42,270 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 23.8 claims per patent with primary concentration in B60L (PROPULSION OF ELECTRICALLY-PROPELLED VEHICLES ; SUPPLYING ELECTRIC POWER FOR AUXILIARY EQUIPMENT OF ELECTRICALLY-PROPELLED VEHICLES ; ELECTRODYNAMIC BRAKE SYSTEMS FOR VEHICLES IN GENERAL ; MAGNETIC SU). As a US Corporation, Powertree Services, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Powertree sits between Power Monitors, Inc. (6 patents, rank #42,266) and PP Energy APS (6 patents, rank #42,274) - the closest US assignees by grant volume. The composite Innovation Score of 44.4/100 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 2 grants, compared with 4 in the 2015–2019 window, a -50% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Powertree Services, Inc.'s 23.8 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Powertree Services, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Powertree's 6 grants land it in the top 26% 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.
