USPTO PatentsView assignee record - 11 granted patents across 18 technology areas, active 2017–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B63B (SHIPS OR OTHER WATERBORNE VESSELS; EQUIPMENT FOR SHIPPING).
The verdict
Nippon holds 11 US patents across 18 technology areas, rank #24,862 of 50,000 tracked assignees.
Nippon Yusen Kabushiki Kaisha has been granted 11 US utility patents between 2017 and 2024, placing Nippon Yusen Kabushiki Kaisha at rank #24,862 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.4 claims per patent with primary concentration in B63B (SHIPS OR OTHER WATERBORNE VESSELS; EQUIPMENT FOR SHIPPING). As a Foreign Corporation, Nippon Yusen Kabushiki Kaisha is one of the more focused assignees in the PatentsView dataset. By volume, Nippon sits between Ningbo Yamao Optoelectronics Co., Ltd. (11 patents, rank #24,858) and Northstar Battery Company, Llc (11 patents, rank #24,866) - the closest US assignees by grant volume. The composite Innovation Score of 34.2/100 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 6 grants, compared with 5 in the 2015–2019 window, a +20% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Nippon Yusen Kabushiki Kaisha's 9.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nippon Yusen Kabushiki Kaisha against peers pursuing similar technology classes.

How to use this portfolio
Nippon's 11 grants land it in the top 53% 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.
