> At least some of those sued were using Red Hat Enterprise Linux (RHEL) on
> the back-end. Google apparently uses its own version of Linux across its
> famously distributed infrastructure.

> Bedrock has also asked for an injunction preventing Google from
> infringing on its patent, but the court has yet to rule on this. Red Hat
> has also intervened in the case, asking the Bedrock patent be ruled
> invalid.
