Portfolio overview

Infrastructure Renewal Institute Of Southern China has been granted 10 US utility patents between 2021 and 2023, placing Infrastructure Renewal Institute Of Southern China at rank #26,584 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.2 claims per patent with primary concentration in F16L (PIPES; JOINTS OR FITTINGS FOR PIPES; SUPPORTS FOR PIPES, CABLES OR PROTECTIVE TUBING; MEANS FOR THERMAL INSULATION IN GENERAL). As a Foreign Corporation, Infrastructure Renewal Institute Of Southern China is one of the more focused assignees in the PatentsView dataset. By volume, Infrastructure sits between Industry-university Cooperation Foundation Sunmoon University (10 patents, rank #26,580) and Innovative Environmental Companies (10 patents, rank #26,588) - the closest US assignees by grant volume. The composite Innovation Score of 29.9/100 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. Historical data spans 2021 through 2023, with 10 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Infrastructure Renewal Institute Of Southern China's 8.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Infrastructure Renewal Institute Of Southern China against peers pursuing similar technology classes.

How to use this portfolio

Infrastructure's 10 grants land it in the top 68% 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 - Infrastructure ranks #26,584 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in F16L - see who else leads that technology area. F16L 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.
