Portfolio overview

Nanotheta Co, Ltd. has been granted 10 US utility patents between 2018 and 2025, placing Nanotheta Co, Ltd. at rank #26,960 across all assignees tracked by PlainPatent. This portfolio spans 19 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.1 claims per patent with primary concentration in C08J (WORKING-UP; GENERAL PROCESSES OF COMPOUNDING; AFTER-TREATMENT NOT COVERED BY SUBCLASSES C08B, C08C, C08F, C08G or C08H). As a Foreign Corporation, Nanotheta Co, Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Nanotheta sits between NVH Korea, Inc. (10 patents, rank #26,956) and National Entertainment Collectibles Association, Inc. (10 patents, rank #26,964) - the closest US assignees by grant volume. The composite Innovation Score of 29.1/100 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 5 grants, compared with 5 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The Foreign 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. Nanotheta Co, Ltd.'s 9.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 19 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nanotheta Co, Ltd. 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.
