Portfolio overview

Xiamen Sanan Optoelectronics Technology Co., Ltd. has been granted 130 US utility patents between 2015 and 2025, placing Xiamen Sanan Optoelectronics Technology Co., Ltd. at rank #2,940 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.4 claims per patent with primary concentration in H10H (INORGANIC LIGHT-EMITTING SEMICONDUCTOR DEVICES HAVING POTENTIAL BARRIERS). As a Foreign Corporation, Xiamen Sanan Optoelectronics Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Xiamen sits between Shanghai United Imaging Intelligence Co., Ltd. (130 patents, rank #2,936) and DISH Network Technologies India Private Limited (129 patents, rank #2,944) - the closest US assignees by grant volume. The composite Innovation Score of 45.7/100 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 47 grants, compared with 83 in the 2015–2019 window, a -43% 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. Xiamen Sanan Optoelectronics Technology Co., Ltd.'s 16.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Xiamen Sanan Optoelectronics Technology Co., Ltd. against peers pursuing similar technology classes.
