USPTO PatentsView assignee record - 154 granted patents across 27 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H10H (INORGANIC LIGHT-EMITTING SEMICONDUCTOR DEVICES HAVING POTENTIAL BARRIERS).
The verdict
Lumens holds 154 US patents across 27 technology areas, rank #2,526 of 50,000 tracked assignees.
Lumens Co., Ltd. has been granted 154 US utility patents between 2015 and 2025, placing Lumens Co., Ltd. at rank #2,526 across all assignees tracked by PlainPatent. This portfolio spans 27 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.6 claims per patent with primary concentration in H10H (INORGANIC LIGHT-EMITTING SEMICONDUCTOR DEVICES HAVING POTENTIAL BARRIERS). As a Foreign Corporation, Lumens Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Lumens sits between CMR Surgical Limited (154 patents, rank #2,522) and Oregon State University (154 patents, rank #2,530) - the closest US assignees by grant volume. The composite Innovation Score of 45.4/100 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 62 grants, compared with 92 in the 2015–2019 window, a -33% 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. Lumens Co., Ltd.'s 14.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 27 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Lumens Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Lumens's 154 grants land it in the top 23% 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.
