Portfolio overview

Advantest Corporation has been granted 437 US utility patents between 2015 and 2025, placing Advantest Corporation at rank #1,004 across all assignees tracked by PlainPatent. This portfolio spans 81 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.4 claims per patent with primary concentration in G01R (MEASURING ELECTRIC VARIABLES; MEASURING MAGNETIC VARIABLES). As a Foreign Corporation, Advantest Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Advantest sits between Samsung Medison Co., Ltd. (439 patents, rank #1,000) and Ferrari S.p.a. (435 patents, rank #1,008) - the closest US assignees by grant volume. The composite Innovation Score of 63.5/100 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 198 grants, compared with 239 in the 2015–2019 window, a -17% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Advantest Corporation's 15.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 81 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Advantest Corporation against peers pursuing similar technology classes.

How to use this portfolio

Advantest's 437 grants land it in the top 2% 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 - Advantest ranks #1,004 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G01R - see who else leads that technology area. G01R 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.
