Portfolio overview

Obayashi Corporation has been granted 9 US utility patents between 2020 and 2024, placing Obayashi Corporation at rank #29,629 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.3 claims per patent with primary concentration in G06T (IMAGE DATA PROCESSING OR GENERATION, IN GENERAL). As a Foreign Corporation, Obayashi Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Obayashi sits between Nylok Llc (9 patents, rank #29,625) and OHKI Co., Ltd. (9 patents, rank #29,633) - the closest US assignees by grant volume. The composite Innovation Score of 35.8/100 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 2020 through 2024, with 9 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. Obayashi Corporation's 11.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Obayashi Corporation against peers pursuing similar technology classes.

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.
