Wistron Corporation (Chinese: 緯創資通股份有限公司; pinyin: Wěichuàng Zītōng Gǔfèn Yǒuxiàn Gōngsī) is a major original design manufacturer in Taiwan. It was the manufacturing arm of Acer Inc., which was spun off in 2000.

Wistron employs over 60,000 people worldwide.[2] As an ODM (original design manufacturer) Wistron designs and manufactures products for other companies to sell under their own brand name. Wistron focuses on ICT (information and communication technology) products, including notebook PCs, desktop PCs, servers, storage, LCD TVs, and handheld devices. Wistron provides a variety of technology services within the design, manufacturing, and after-sales service functions tailored to meet customers' specific requirements. [3]

In July 2011, Wistron and Microsoft entered into an agreement that offered coverage under Microsoft's exclusive rights portfolio for Wistron products including tablets, mobile phones and other devices running the Chrome OS or Android platform.[4] In September 2011, Wistron signed a patent licensing agreement with Intellectual Ventures.[5]
