Portfolio overview

National Flooring Equipment, Inc. has been granted 12 US utility patents between 2019 and 2024, placing National Flooring Equipment, Inc. at rank #23,072 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.1 claims per patent with primary concentration in B24C (ABRASIVE OR RELATED BLASTING WITH PARTICULATE MATERIAL). As a US Corporation, National Flooring Equipment, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, National sits between Nanotech Industrial Solutions (12 patents, rank #23,068) and Naturalmotion Ltd. (12 patents, rank #23,076) - the closest US assignees by grant volume. The composite Innovation Score of 38.1/100 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 10 grants, compared with 2 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. National Flooring Equipment, Inc.'s 11.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark National Flooring Equipment, Inc. 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.
