Portfolio overview

Akita Prefecture has been granted 5 US utility patents between 2016 and 2025, placing Akita Prefecture at rank #44,472 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.6 claims per patent with primary concentration in H10N (ELECTRIC SOLID-STATE DEVICES NOT OTHERWISE PROVIDED FOR). As a Foreign Government, Akita Prefecture is one of the more focused assignees in the PatentsView dataset. By volume, Akita sits between Aiviva Biopharma, Inc. (5 patents, rank #44,468) and Albea Lacrost (5 patents, rank #44,476) - the closest US assignees by grant volume. The composite Innovation Score of 29.2/100 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 3 grants, compared with 2 in the 2015–2019 window, a +50% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Government 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. Akita Prefecture's 8.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Akita Prefecture against peers pursuing similar technology classes.

How to use this portfolio

Akita's 5 grants land it in the top 70% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Akita ranks #44,472 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H10N - see who else leads that technology area. H10N leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
