USPTO PatentsView assignee record - 10 granted patents across 11 technology areas, active 2015–2018. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: C12N (MICROORGANISMS OR ENZYMES; COMPOSITIONS THEREOF; PROPAGATING, PRESERVING, OR MAINTAINING MICROORGANISMS; MUTATION OR GENETIC ENGINEERING; CULTURE MEDIA).
The verdict
Okayama holds 10 US patents across 11 technology areas, rank #27,014 of 50,000 tracked assignees.
Okayama Prefecture has been granted 10 US utility patents between 2015 and 2018, placing Okayama Prefecture at rank #27,014 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.7 claims per patent with primary concentration in C12N (MICROORGANISMS OR ENZYMES; COMPOSITIONS THEREOF; PROPAGATING, PRESERVING, OR MAINTAINING MICROORGANISMS; MUTATION OR GENETIC ENGINEERING; CULTURE MEDIA). As a Foreign Corporation, Okayama Prefecture is one of the more focused assignees in the PatentsView dataset. By volume, Okayama sits between Oculentis Holding B.v. (10 patents, rank #27,010) and OMNI Solutions Llc (10 patents, rank #27,018) - the closest US assignees by grant volume. The composite Innovation Score of 27.0/100 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 0 grants, compared with 10 in the 2015–2019 window, a -100% 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. Okayama Prefecture's 11.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Okayama Prefecture against peers pursuing similar technology classes.

How to use this portfolio
Okayama's 10 grants land it in the top 78% 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.
