The verdict
Nine holds 5 US patents across 1 technology areas, rank #49,177 of 50,000 tracked assignees.
Nine Energy Canada, Inc. has been granted 5 US utility patents between 2015 and 2020, placing Nine Energy Canada, Inc. at rank #49,177 across all assignees tracked by PlainPatent. This portfolio spans 1 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.0 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, Nine Energy Canada, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Nine sits between Nfusion Vascular Systems, Llc (5 patents, rank #49,173) and Ningbo Exquisite Electrical Appliance Co., Ltd. (5 patents, rank #49,181) - the closest US assignees by grant volume. The composite Innovation Score of 16.3/100 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 4 in the 2015–2019 window, a -75% 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. Nine Energy Canada, Inc.'s 11.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 1 subclass reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nine Energy Canada, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Nine's 5 grants land it in the top 96% 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.
