Portfolio overview

NTT Security Holdings Corporation has been granted 5 US utility patents between 2020 and 2025, placing NTT Security Holdings Corporation at rank #49,087 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.2 claims per patent with primary concentration in H04L (TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION). As a Foreign Corporation, NTT Security Holdings Corporation is one of the more focused assignees in the PatentsView dataset. By volume, NTT sits between Ntherma Corporation (5 patents, rank #49,083) and Nuova OMPI S.r.l. Unipersonale (5 patents, rank #49,091) - the closest US assignees by grant volume. The composite Innovation Score of 41.8/100 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 2020 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 Security Holdings Corporation's 14.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NTT Security Holdings Corporation against peers pursuing similar technology classes.

How to use this portfolio

NTT's 5 grants land it in the top 32% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - NTT ranks #49,087 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H04L - see who else leads that technology area. H04L leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
