The verdict
Oldcastle holds 27 US patents across 9 technology areas, rank #11,375 of 50,000 tracked assignees.
Oldcastle Building Products Canada Inc. has been granted 27 US utility patents between 2015 and 2024, placing Oldcastle Building Products Canada Inc. at rank #11,375 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.4 claims per patent with primary concentration in E04F (FINISHING WORK ON BUILDINGS, e.g. STAIRS, FLOORS). As a Foreign Corporation, Oldcastle Building Products Canada Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Oldcastle sits between Origin Company, Limited (27 patents, rank #11,371) and Optumsoft, Inc. (27 patents, rank #11,379) - the closest US assignees by grant volume. The composite Innovation Score of 35.7/100 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 9 grants, compared with 18 in the 2015–2019 window, a -50% 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. Oldcastle Building Products Canada Inc.'s 13.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Oldcastle Building Products Canada Inc. against peers pursuing similar technology classes.

How to use this portfolio
Oldcastle's 27 grants land it in the top 48% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
