USPTO PatentsView assignee record - 10 granted patents across 16 technology areas, active 2016–2021. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES).
The verdict
Maruha holds 10 US patents across 16 technology areas, rank #26,786 of 50,000 tracked assignees.
Maruha Nichiro Corporation has been granted 10 US utility patents between 2016 and 2021, placing Maruha Nichiro Corporation at rank #26,786 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.5 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a Foreign Corporation, Maruha Nichiro Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Maruha sits between Mallinckrodt Nuclear Medicine Llc (10 patents, rank #26,782) and Material Concept, Inc. (10 patents, rank #26,790) - the closest US assignees by grant volume. The composite Innovation Score of 27.5/100 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 8 in the 2015–2019 window, a -75% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign 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. Maruha Nichiro Corporation's 8.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 16 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Maruha Nichiro Corporation against peers pursuing similar technology classes.

How to use this portfolio
Maruha's 10 grants land it in the top 76% 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.
