USPTO PatentsView assignee record - 52 granted patents across 12 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: C07D (HETEROCYCLIC COMPOUNDS).
The verdict
Nihon holds 52 US patents across 12 technology areas, rank #6,471 of 50,000 tracked assignees.
Nihon Nohyaku Co., Ltd. has been granted 52 US utility patents between 2015 and 2025, placing Nihon Nohyaku Co., Ltd. at rank #6,471 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.6 claims per patent with primary concentration in C07D (HETEROCYCLIC COMPOUNDS). As a Foreign Corporation, Nihon Nohyaku Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Nihon sits between Mirus Llc (52 patents, rank #6,467) and Outbrain Inc. (52 patents, rank #6,475) - the closest US assignees by grant volume. The composite Innovation Score of 34.1/100 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 21 grants, compared with 31 in the 2015–2019 window, a -32% 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. Nihon Nohyaku Co., Ltd.'s 7.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nihon Nohyaku Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Nihon's 52 grants land it in the top 54% 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.
