Mojang AB

Mojang AB, now trading as Mojang Studios, is a Swedish video game developer headquartered in Stockholm. Founded in 2009 by Markus "Notch" Persson, the company was officially incorporated as Mojang AB in 2010. In a high-profile deal, Microsoft acquired Mojang for $2.5 billion in November 2014, and it now operates as a subsidiary of Microsoft's Xbox Game Studios. As of 2021, the company employed approximately 600 people. Mojang is a private company and its financials are consolidated within Microsoft's.

Mojang's primary business is the development and maintenance of the video game Minecraft, which is the best-selling video game of all time. The game is a "sandbox" title that allows players to build, explore, and survive in a 3D-generated world of blocks. The company has expanded the franchise to include spin-off games such as Minecraft Dungeons, Minecraft Legends, and the now-discontinued Minecraft Earth. Mojang also develops educational versions of the game and oversees a large ecosystem of merchandise and media related to the Minecraft brand.

As an operating company, Mojang's patent litigation posture is that of a defendant. The company has no record as a plaintiff in the tracked database. Its single tracked case as a defendant was filed in the Eastern District of Texas, a venue historically popular with patent plaintiffs. This posture is consistent with a successful technology company being targeted by a non-practicing entity (NPE).

The company's most notable litigation is the case Uniloc Luxembourg S.A. v. Mojang AB, filed in 2012. The suit was brought by Uniloc, which has been characterized as a patent assertion entity, often referred to as a "patent troll." The lawsuit alleged that the license-checking function in the Android version of Minecraft infringed on a Uniloc patent covering a "system and method for preventing unauthorized access to electronic data." The case also named other prominent game developers as defendants in similar suits.
