USPTO PatentsView assignee record - 2,641 granted patents across 103 technology areas, active 2020–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G11C (STATIC STORES).
The verdict
Kioxia holds 2,641 US patents across 103 technology areas, rank #145 of 50,000 tracked assignees.
Kioxia Corporation has been granted 2,641 US utility patents between 2020 and 2025, placing Kioxia Corporation at rank #145 across all assignees tracked by PlainPatent. This portfolio spans 103 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.2 claims per patent with primary concentration in G11C (STATIC STORES). As a Foreign Corporation, Kioxia Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Kioxia sits between NXP USA, Inc. (2,671 patents, rank #141) and Semiconductor Components Industries, Llc (2,555 patents, rank #149) - the closest US assignees by grant volume. The composite Innovation Score of 81.9/100 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 2,641 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. Kioxia Corporation's 16.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kioxia Corporation against peers pursuing similar technology classes.

How to use this portfolio
Kioxia's 2,641 grants land it in the top 0.1% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
