The verdict
Nammu21 holds 5 US patents across 2 technology areas, rank #48,936 of 50,000 tracked assignees.
Nammu21, Inc. has been granted 5 US utility patents between 2022 and 2025, placing Nammu21, Inc. at rank #48,936 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.0 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a US Corporation, Nammu21, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Nammu21 sits between NAD Grid Corp (5 patents, rank #48,932) and Nanjing Haohui HI TECH Co., Ltd. (5 patents, rank #48,940) - the closest US assignees by grant volume. The composite Innovation Score of 34.2/100 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. Historical data spans 2022 through 2025, with 5 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Nammu21, Inc.'s 5.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nammu21, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Nammu21's 5 grants land it in the top 53% 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.
