Portfolio overview

Louisiana-pacific Corp. has been granted 38 US utility patents between 2019 and 2025, placing Louisiana-pacific Corp. at rank #8,428 across all assignees tracked by PlainPatent. This portfolio spans 31 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.3 claims per patent with primary concentration in E04F (FINISHING WORK ON BUILDINGS, e.g. STAIRS, FLOORS). As a US Corporation, Louisiana-pacific Corp. is one of the more focused assignees in the PatentsView dataset. By volume, Louisiana-pacific sits between Kyorin Pharmaceutical Co., Ltd. (38 patents, rank #8,424) and Mloptic Corp. (38 patents, rank #8,432) - the closest US assignees by grant volume. The composite Innovation Score of 58.0/100 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 37 grants, compared with 1 in the 2015–2019 window, a +3600% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Louisiana-pacific Corp.'s 14.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 31 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Louisiana-pacific Corp. 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.
