Portfolio overview

National Center FOR Nanoscience AND Technology has been granted 11 US utility patents between 2015 and 2025, placing National Center FOR Nanoscience AND Technology at rank #24,831 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.4 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a Foreign Corporation, National Center FOR Nanoscience AND Technology is one of the more focused assignees in the PatentsView dataset. By volume, National sits between Namecheap, Inc. (11 patents, rank #24,827) and National University Corporation Shiga University OF Medical Science (11 patents, rank #24,835) - the closest US assignees by grant volume. The composite Innovation Score of 38.3/100 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 7 grants, compared with 4 in the 2015–2019 window, a +75% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. National Center FOR Nanoscience AND Technology's 11.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 21 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark National Center FOR Nanoscience AND Technology against peers pursuing similar technology classes.
