Portfolio overview

Shiroki Corporation has been granted 162 US utility patents between 2015 and 2023, placing Shiroki Corporation at rank #2,413 across all assignees tracked by PlainPatent. This portfolio spans 34 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.7 claims per patent with primary concentration in B60N (SEATS SPECIALLY ADAPTED FOR VEHICLES; VEHICLE PASSENGER ACCOMMODATION NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Shiroki Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Shiroki sits between Faurecia Interieur Industrie (162 patents, rank #2,409) and Aol (161 patents, rank #2,417) - the closest US assignees by grant volume. The composite Innovation Score of 43.3/100 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 44 grants, compared with 118 in the 2015–2019 window, a -63% 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. Shiroki Corporation's 6.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 34 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shiroki Corporation against peers pursuing similar technology classes.

How to use this portfolio

Shiroki's 162 grants land it in the top 28% 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 - Shiroki ranks #2,413 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in B60N - see who else leads that technology area. B60N 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.
