Portfolio overview

National Presto Industries, Inc. has been granted 86 US utility patents between 2015 and 2025, placing National Presto Industries, Inc. at rank #4,164 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.1 claims per patent with primary concentration in A47J (KITCHEN EQUIPMENT; COFFEE MILLS; SPICE MILLS; APPARATUS FOR MAKING BEVERAGES). As a US Corporation, National Presto Industries, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, National sits between Kellogg Brown & Root Llc (86 patents, rank #4,160) and Plastic Omnium Advanced Innovation And Research (86 patents, rank #4,168) - the closest US assignees by grant volume. The composite Innovation Score of 37.6/100 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 51 grants, compared with 35 in the 2015–2019 window, a +46% 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 Presto Industries, Inc.'s 5.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 16 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark National Presto Industries, 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.
