The Supreme Court today sided with Microsoft in another important patent case filed by AT&T. The case centered around whether selling Windows overseas infringed on AT&T's patents that are in Windows. Microsoft argued [PDF] that the copies being sold in Asia were "...not technically supplied from the United States because overseas manufacturers of its computers made copies of the software from a master disk and installed those copies into the operating system. Microsoft said it could not be considered a supplier since the copies, not the original software, were in the computers built abroad." Now, while I support the weakening of software patents in general, by this logic, would that mean that MS's patents don't apply to those that use pirated copies of Windows?
