Portfolio overview

Research Institute Of Highway Ministry Of Transport has been granted 16 US utility patents between 2015 and 2025, placing Research Institute Of Highway Ministry Of Transport at rank #18,049 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.4 claims per patent with primary concentration in E01C (CONSTRUCTION OF, OR SURFACES FOR, ROADS, SPORTS GROUNDS, OR THE LIKE; MACHINES OR AUXILIARY TOOLS FOR CONSTRUCTION OR REPAIR). As a Foreign Corporation, Research Institute Of Highway Ministry Of Transport is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 50.7/100 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 11 grants, compared with 5 in the 2015–2019 window, a +120% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Research Institute Of Highway Ministry Of Transport's 8.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Research Institute Of Highway Ministry Of Transport against peers pursuing similar technology classes.
