USPTO PatentsView assignee record - 350 granted patents across 66 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H01J (ELECTRIC DISCHARGE TUBES OR DISCHARGE LAMPS).
The verdict
JEOL holds 350 US patents across 66 technology areas, rank #1,215 of 50,000 tracked assignees.
JEOL Ltd. has been granted 350 US utility patents between 2015 and 2025, placing JEOL Ltd. at rank #1,215 across all assignees tracked by PlainPatent. This portfolio spans 66 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.3 claims per patent with primary concentration in H01J (ELECTRIC DISCHARGE TUBES OR DISCHARGE LAMPS). As a Foreign Corporation, JEOL Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, JEOL sits between Clarion Co., Ltd. (350 patents, rank #1,211) and Deutsche Telekom Ag (349 patents, rank #1,219) - the closest US assignees by grant volume. The composite Innovation Score of 56.4/100 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 227 grants, compared with 123 in the 2015–2019 window, a +85% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. JEOL Ltd.'s 8.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 66 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark JEOL Ltd. against peers pursuing similar technology classes.

How to use this portfolio
JEOL's 350 grants land it in the top 6% 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.
