According to Associated Press, the main problem is whether Vole has to shell out cash for violating an AT&T patent overseas. AT&T patented technology that converts speech into computer code, so that speech can be transmitted electronically. Vole developed similar capabilities in Windows and has acknowledged that it violated the AT&T patent domestically.
However it does not think it should pay up for infringement when its software was shipped overseas.
AT&T wants Microsoft to pay up for all those versions of Windows that were installed in each foreign computer. Vole says that all it had to was send its partners a distribution disk and if it has to pay for foreign installations AT&T should just be chasing its partners and suing them under local laws.
So far two lower federal courts ruled in favour of AT&T. The Supreme Court is expected to decide the case by July.
