Portfolio overview
XIAMEN SAN'AN OPTOELECTRONICS CO., LTD. has been granted 72 US utility patents between 2018 and 2025, placing XIAMEN SAN'AN OPTOELECTRONICS CO., LTD. at rank #4,855 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.8 claims per patent with primary concentration in H10H (INORGANIC LIGHT-EMITTING SEMICONDUCTOR DEVICES HAVING POTENTIAL BARRIERS). As a Foreign Corporation, XIAMEN SAN'AN OPTOELECTRONICS CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 45.8/100 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 64 grants, compared with 8 in the 2015–2019 window — a +700% 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. XIAMEN SAN'AN OPTOELECTRONICS CO., LTD.'s 17.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark XIAMEN SAN'AN OPTOELECTRONICS CO., LTD. against peers pursuing similar technology classes.
