The verdict
Fujitsu holds 6 US patents across 8 technology areas, rank #40,232 of 50,000 tracked assignees.
Fujitsu Semiconductor Memory Solution Limited has been granted 6 US utility patents between 2020 and 2024, placing Fujitsu Semiconductor Memory Solution Limited at rank #40,232 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.0 claims per patent with primary concentration in G11C (STATIC STORES). As a Foreign Corporation, Fujitsu Semiconductor Memory Solution Limited is one of the more focused assignees in the PatentsView dataset. By volume, Fujitsu sits between Fujian Jing'an Optoelectronics Co., Ltd. (6 patents, rank #40,228) and Fulterer Ag & Co KG (6 patents, rank #40,236) - the closest US assignees by grant volume. The composite Innovation Score of 27.3/100 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 2024, with 6 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. Fujitsu Semiconductor Memory Solution Limited's 12.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Fujitsu Semiconductor Memory Solution Limited against peers pursuing similar technology classes.

How to use this portfolio
Fujitsu's 6 grants land it in the top 77% 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.
