Applied Optoelectronics, Inc.

Applied Optoelectronics Inc. (AOI) is a publicly traded company headquartered in Sugar Land, Texas, founded in 1997. Trading on NASDAQ under the ticker AAOI, the company reported a trailing twelve-month revenue of $507 million as of March 31, 2026, and a market capitalization of approximately $14.6 billion as of May 22, 2026. AOI employs around 4,691 individuals.

AOI designs, develops, and manufactures fiber-optic networking products for internet data centers, Cable Television (CATV), telecom, and Fiber-to-the-Home (FTTH) markets. Key product offerings include optical devices, packaged optical components, laser transmitters, and fiber optic transceivers, particularly high-speed 800G and 1.6T transceivers crucial for AI datacenter buildouts. The company maintains a vertically integrated manufacturing model, fabricating its own laser chips, and operates R&D and manufacturing facilities in the U.S., Taiwan, and previously in China (with an announced intention to sell the Chinese operations in 2022). They also offer HFC networking products, including Quantum12™ HFC amplifiers and the QuantumLink™ HFC Remote Management solution, which includes AI intelligence modules for network optimization.

Applied Optoelectronics Inc. appears to operate as an operating company defending its technology. The company has no tracked cases as a plaintiff and two tracked cases as a defendant, both within the Patent Trial and Appeal Board (PTAB). This posture suggests that AOI is primarily engaged in developing and selling its core products and defends against challenges to its patents or those asserted against it.

The two recorded cases, "Untitled case" and "CAMBRIDGE INDUSTRIES USA, INC. et al. v. Applied Optoelectronics Inc.," both list Applied Optoelectronics Inc. as a defendant and were filed on April 1, 2025, in the PTAB. Recent company context includes a partnership with Microsoft for laser development and a strategic move to divest its Chinese manufacturing facilities to focus on its core laser technology and U.S./Taiwan operations. The company has also seen significant demand for its high-speed optical transceivers driven by the expansion of AI-enabled data centers.
