Portfolio overview

NOV Process & Flow Technologies US, Inc. has been granted 6 US utility patents between 2019 and 2025, placing NOV Process & Flow Technologies US, Inc. at rank #41,905 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.8 claims per patent with primary concentration in B01D (SEPARATION). As a US Corporation, NOV Process & Flow Technologies US, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, NOV sits between North American Specialty Products Llc (6 patents, rank #41,901) and Novum Engineering Gmbh (6 patents, rank #41,909) - the closest US assignees by grant volume. The composite Innovation Score of 34.6/100 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 5 grants, compared with 1 in the 2015–2019 window, a +400% 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. NOV Process & Flow Technologies US, Inc.'s 17.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NOV Process & Flow Technologies US, Inc. against peers pursuing similar technology classes.
