Portfolio overview

Building Materials Investment Corporation has been granted 151 US utility patents between 2015 and 2022, placing Building Materials Investment Corporation at rank #2,574 across all assignees tracked by PlainPatent. This portfolio spans 54 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.2 claims per patent with primary concentration in E04D (ROOF COVERINGS; SKY-LIGHTS; GUTTERS; ROOF-WORKING TOOLS). As a US Corporation, Building Materials Investment Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Building sits between Amada Co., Ltd. (151 patents, rank #2,570) and Pusan National University Industry-university Cooperation Foundation (151 patents, rank #2,578) - the closest US assignees by grant volume. The composite Innovation Score of 48.9/100 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. Between 2020 and 2025 the company received 34 grants, compared with 117 in the 2015–2019 window, a -71% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. Building Materials Investment Corporation's 10.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 54 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Building Materials Investment Corporation against peers pursuing similar technology classes.

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.
