The verdict
Epson holds 5 US patents across 8 technology areas, rank #46,610 of 50,000 tracked assignees.
Epson Imaging Devices Corporation has been granted 5 US utility patents between 2015 and 2016, placing Epson Imaging Devices Corporation at rank #46,610 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.2 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, Epson Imaging Devices Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Epson sits between Epiq Solutions (5 patents, rank #46,606) and Eris Innovations, Llc (5 patents, rank #46,614) - the closest US assignees by grant volume. The composite Innovation Score of 25.3/100 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. Between 2020 and 2025 the company received 0 grants, compared with 5 in the 2015–2019 window, a -100% 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. Epson Imaging Devices Corporation's 15.2 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 Epson Imaging Devices Corporation against peers pursuing similar technology classes.

How to use this portfolio
Epson's 5 grants land it in the top 83% 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.
