Portfolio overview

National Diversified Sales, Inc. has been granted 14 US utility patents between 2015 and 2024, placing National Diversified Sales, Inc. at rank #20,156 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.3 claims per patent with primary concentration in F16L (PIPES; JOINTS OR FITTINGS FOR PIPES; SUPPORTS FOR PIPES, CABLES OR PROTECTIVE TUBING; MEANS FOR THERMAL INSULATION IN GENERAL). As a US Corporation, National Diversified Sales, Inc. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 46.5/100 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 8 grants, compared with 6 in the 2015–2019 window, a +33% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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 Diversified Sales, Inc.'s 7.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark National Diversified Sales, Inc. against peers pursuing similar technology classes.
