The verdict

This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.1 claims per patent with primary concentration in C10L (FUELS NOT OTHERWISE PROVIDED FOR; NATURAL GAS; SYNTHETIC NATURAL GAS OBTAINED BY PROCESSES NOT COVERED BY SUBCLASSES C10G OR C10K; LIQUIFIED PETROLEUM GAS; USE OF ADDITIVES TO FUELS OR FIRES; FIRE-LIG). As a US Corporation, Sunoco Partners Marketing & Terminals L.p. is one of the more focused assignees in the PatentsView dataset. By volume, Sunoco sits between Suncall Technologies (sz) Co., Ltd (8 patents, rank #33,284) and Suzhou Alphamab Co., Ltd. (8 patents, rank #33,292) - the closest US assignees by grant volume. The composite Innovation Score of 26.0/100 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 0 grants, compared with 8 in the 2015–2019 window, a -100% 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. Sunoco Partners Marketing & Terminals L.p.'s 15.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sunoco Partners Marketing & Terminals L.p. against peers pursuing similar technology classes.

How to use this portfolio
Sunoco's 8 grants land it in the top 81% 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.
