Portfolio overview
Total E&P Canada Ltd. has been granted 9 US utility patents between 2015 and 2020, placing Total E&P Canada Ltd. at rank #30,421 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.4 claims per patent with primary concentration in E21B (EARTH OR ROCK DRILLING; OBTAINING OIL, GAS, WATER, SOLUBLE OR MELTABLE MATERIALS OR A SLURRY OF MINERALS FROM WELLS). As a Foreign Corporation, Total E&P Canada Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Total sits between Tokyo University Of Pharmacy And Life Sciences (9 patents, rank #30,417) and Trace-ability, Inc. (9 patents, rank #30,425) - the closest US assignees by grant volume. The composite Innovation Score of 26.6/100 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 1 grants, compared with 8 in the 2015–2019 window, a -87% 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. Total E&P Canada Ltd.'s 14.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Total E&P Canada Ltd. against peers pursuing similar technology classes.
