Portfolio overview

Lakehead University has been granted 11 US utility patents between 2017 and 2025, placing Lakehead University at rank #24,674 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.8 claims per patent with primary concentration in C01B (NON-METALLIC ELEMENTS; COMPOUNDS THEREOF; ; METALLOIDS OR COMPOUNDS THEREOF NOT COVERED BY SUBCLASS C01C). As a Foreign Corporation, Lakehead University is one of the more focused assignees in the PatentsView dataset. By volume, Lakehead sits between L-3 Communications Cincinnati Electronics Corporation (11 patents, rank #24,670) and Laurel Machinery Co., Ltd. (11 patents, rank #24,678) - the closest US assignees by grant volume. The composite Innovation Score of 36.5/100 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 6 grants, compared with 5 in the 2015–2019 window, a +20% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Lakehead University's 10.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 28 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Lakehead University 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.
