The verdict
Japan holds 5,401 US patents across 119 technology areas, rank #68 of 50,000 tracked assignees.
Japan Display Inc. has been granted 5,401 US utility patents between 2015 and 2025, placing Japan Display Inc. at rank #68 across all assignees tracked by PlainPatent. This portfolio spans 119 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.4 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, Japan Display Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Japan sits between SAP SE (5,717 patents, rank #64) and Vmware Llc (4,914 patents, rank #72) - the closest US assignees by grant volume. The composite Innovation Score of 67.4/100 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 2,690 grants, compared with 2,711 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. Japan Display Inc.'s 11.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, 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 Japan Display Inc. against peers pursuing similar technology classes.

How to use this portfolio
Japan's 5,401 grants land it in the top 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.
