USPTO PatentsView assignee record - 77 granted patents across 69 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B25J (MANIPULATORS; CHAMBERS PROVIDED WITH MANIPULATION DEVICES).
The verdict
Nitta holds 77 US patents across 69 technology areas, rank #4,572 of 50,000 tracked assignees.
Nitta Corporation has been granted 77 US utility patents between 2015 and 2025, placing Nitta Corporation at rank #4,572 across all assignees tracked by PlainPatent. This portfolio spans 69 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.9 claims per patent with primary concentration in B25J (MANIPULATORS; CHAMBERS PROVIDED WITH MANIPULATION DEVICES). As a Foreign Corporation, Nitta Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Nitta sits between Lighting Science Group Corporation (77 patents, rank #4,568) and Norton (waterford) Limited (77 patents, rank #4,576) - the closest US assignees by grant volume. The composite Innovation Score of 49.3/100 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 40 grants, compared with 37 in the 2015–2019 window, a +8% 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. Nitta Corporation's 6.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 69 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nitta Corporation against peers pursuing similar technology classes.

How to use this portfolio
Nitta's 77 grants land it in the top 15% 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.
