Portfolio overview

NTT Docomo, Inc. has been granted 2,283 US utility patents between 2015 and 2025, placing NTT Docomo, Inc. at rank #170 across all assignees tracked by PlainPatent. This portfolio spans 76 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.8 claims per patent with primary concentration in H04W (WIRELESS COMMUNICATION NETWORKS). As a Foreign Corporation, NTT Docomo, Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, NTT sits between Eaton Intelligent Power Limited (2,308 patents, rank #166) and Depuy Synthes Products, Inc. (2,257 patents, rank #174) - the closest US assignees by grant volume. The composite Innovation Score of 65.2/100 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. Between 2020 and 2025 the company received 1,335 grants, compared with 948 in the 2015–2019 window, a +41% 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. NTT Docomo, Inc.'s 7.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 76 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NTT Docomo, Inc. against peers pursuing similar technology classes.

How to use this portfolio

NTT's 2,283 grants land it in the top 1% 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 #170 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H04W - see who else leads that technology area. H04W 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.
