Microsoft files amicus brief in support of Anthropic's lawsuit with US DOD

Microsoft filed on Tuesday a proposed brief in support of Anthropic's lawsuit asking the court to temporarily block ‌the ⁠U.S. ⁠Department of Defense's designation of the AI startup as a supply-chain risk.

Microsoft added that it was directly impacted by the DOD's ⁠designation.

The Claude ‌maker had filed a lawsuit to ⁠block the Pentagon from placing it on a national security blacklist on Monday, escalating a high-stakes battle with the US military over usage ‌restrictions on its technology.


Microsoft's filing argued the TRO is needed ⁠to prevent costly disruptions for suppliers, who would otherwise have to rapidly rebuild offerings that rely on Anthropic's products.
