USPTO PatentsView assignee record - 207 granted patents across 30 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G02F (OPTICAL DEVICES OR ARRANGEMENTS FOR THE CONTROL OF LIGHT BY MODIFICATION OF THE OPTICAL PROPERTIES OF THE MEDIA OF THE ELEMENTS INVOLVED THEREIN; NON-LINEAR OPTICS; FREQUENCY-CHANGING OF LIGHT; OPTICA).
The verdict
Fujitsu holds 207 US patents across 30 technology areas, rank #1,937 of 50,000 tracked assignees.
Fujitsu Optical Components Limited has been granted 207 US utility patents between 2015 and 2025, placing Fujitsu Optical Components Limited at rank #1,937 across all assignees tracked by PlainPatent. This portfolio spans 30 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.7 claims per patent with primary concentration in G02F (OPTICAL DEVICES OR ARRANGEMENTS FOR THE CONTROL OF LIGHT BY MODIFICATION OF THE OPTICAL PROPERTIES OF THE MEDIA OF THE ELEMENTS INVOLVED THEREIN; NON-LINEAR OPTICS; FREQUENCY-CHANGING OF LIGHT; OPTICA). As a Foreign Corporation, Fujitsu Optical Components Limited is one of the more focused assignees in the PatentsView dataset. By volume, Fujitsu sits between Rain Bird Corporation (208 patents, rank #1,933) and Safran Nacelles (207 patents, rank #1,941) - the closest US assignees by grant volume. The composite Innovation Score of 51.5/100 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 103 grants, compared with 104 in the 2015–2019 window, a -1% 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. Fujitsu Optical Components Limited's 9.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 30 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Fujitsu Optical Components Limited against peers pursuing similar technology classes.

How to use this portfolio
Fujitsu's 207 grants land it in the top 11% 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.
