Shenzhen Qianfenyi Intelligent Technology Co., Ltd.

Shenzhen Qianfenyi Intelligent Technology Co., Ltd., which also operates under the brand name Maxeye, is a private company based in Shenzhen, China, founded in 2014. It is a high-tech enterprise that researches, develops, and produces intelligent touch and writing devices, primarily active stylus pens. The company describes itself as the largest shipper of these products in China and the third-largest globally. Publicly available information on the company's revenue and exact employee count is not available, though one business directory estimates its employee count between 100-200 people.

Maxeye's core business is the design and manufacture of active capacitive styluses compatible with a wide range of devices, including smartphones, iPads, Android tablets, Windows laptops, and Chromebooks. The company holds over 300 patents related to active stylus technology and has obtained official authorization for Microsoft Pen Protocol (MPP) and Universal Stylus Initiative (USI) products. Maxeye provides its products as an original equipment manufacturer (OEM) and also markets them under its own "Metapen" brand. Its product listings include styluses for specific devices like the "Metapen Pencil D1".

As a defendant in its only tracked U.S. patent litigation case, Shenzhen Qianfenyi appears to be an operating company defending its products. This is consistent with its stated business of manufacturing and selling styluses. The single case was filed in the U.S. District Court for the Eastern District of Texas, a venue known for patent litigation.

The notable case is Wacom Co., Ltd. v. Shenzhen Qianfenyi Intelligent Technology Co., Ltd., filed in August 2024. Wacom, a major Japanese manufacturer of pen tablets and digital interface technology, alleges that Maxeye's active stylus products infringe on seven of Wacom's patents. The lawsuit specifically targets the importation and sale of Maxeye's styluses in the U.S., including those compliant with the USI specification. The litigation has also involved efforts by Wacom to gather evidence from third-party component suppliers, such as a Bengaluru-based semiconductor manufacturer that allegedly supplies integrated circuits for the stylus products.
