The verdict
Marubeni-itochu holds 5 US patents across 5 technology areas, rank #48,552 of 50,000 tracked assignees.
Marubeni-itochu Tubulars America Inc. has been granted 5 US utility patents between 2016 and 2021, placing Marubeni-itochu Tubulars America Inc. at rank #48,552 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.4 claims per patent with primary concentration in F16L (PIPES; JOINTS OR FITTINGS FOR PIPES; SUPPORTS FOR PIPES, CABLES OR PROTECTIVE TUBING; MEANS FOR THERMAL INSULATION IN GENERAL). As a US Corporation, Marubeni-itochu Tubulars America Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Marubeni-itochu sits between Martin Christ Gefriertrocknungsanlagen Gmbh (5 patents, rank #48,548) and Matia Robotics Mekatronik Sistemler AR-GE Muhendislik Yazilim Sanayi VE Ticaret Anonim Sirketi (5 patents, rank #48,556) - the closest US assignees by grant volume. The composite Innovation Score of 23.9/100 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 3 in the 2015–2019 window, a -33% 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. Marubeni-itochu Tubulars America Inc.'s 16.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Marubeni-itochu Tubulars America Inc. against peers pursuing similar technology classes.

How to use this portfolio
Marubeni-itochu's 5 grants land it in the top 87% 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.
