Marathon Petroleum Company LP

Marathon Petroleum Company LP has been granted 141 US utility patents between 2015 and 2025, placing Marathon Petroleum Company LP at rank #2,745 across all assignees tracked by PlainPatent. This portfolio spans 54 distinct Cooperative Patent Classification (CPC) subclasses, averaging 22.4 claims per patent with primary concentration in C10G (CRACKING HYDROCARBON OILS; PRODUCTION OF LIQUID HYDROCARBON MIXTURES, e.g. BY DESTRUCTIVE HYDROGENATION, OLIGOMERISATION, POLYMERISATION ; RECOVERY OF HYDROCARBON OILS FROM OIL-SHALE, OIL-SAND, OR GAS). As a US Corporation, Marathon Petroleum Company LP is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 75.6/100 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 124 grants, compared with 17 in the 2015–2019 window — a +629% 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. Marathon Petroleum Company LP's 22.4 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 54 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Marathon Petroleum Company LP against peers pursuing similar technology classes.
