Portfolio overview

Gigaphoton Inc. has been granted 411 US utility patents between 2015 and 2025, placing Gigaphoton Inc. at rank #1,053 across all assignees tracked by PlainPatent. This portfolio spans 54 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.0 claims per patent with primary concentration in H05G (X-RAY TECHNIQUE). As a Foreign Corporation, Gigaphoton Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Gigaphoton sits between Andreas Stihl Ag & Co. KG (412 patents, rank #1,049) and Fluke Corporation (408 patents, rank #1,057) - the closest US assignees by grant volume. The composite Innovation Score of 59.2/100 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 203 grants, compared with 208 in the 2015–2019 window, a -2% 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. Gigaphoton Inc.'s 15.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 54 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Gigaphoton Inc. against peers pursuing similar technology classes.

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.
