Portfolio overview
NTT Innovative Devices Corporation has been granted 5 US utility patents between 2024 and 2025, placing NTT Innovative Devices Corporation at rank #49,086 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.6 claims per patent with primary concentration in H04L (TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION). As a Foreign Corporation, NTT Innovative Devices Corporation is one of the more focused assignees in the PatentsView dataset. By volume, NTT sits between NTA Enterprise (5 patents, rank #49,082) and Numnum, Llc (5 patents, rank #49,090) - the closest US assignees by grant volume. The composite Innovation Score of 34.6/100 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. Historical data spans 2024 through 2025, with 5 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. NTT Innovative Devices Corporation's 9.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NTT Innovative Devices Corporation against peers pursuing similar technology classes.
