Microsoft may have to pull Office suite from the shelves in South Korea after losing a patent suit.
A South Korean Supreme Court has refused a request from Microsoft that patents obtained by Hankuk Aviation University professor Lee Keung-Haie in 1997 be nullified.

The decision strengthens the case of Lee and the company acting as his agent, called P and IB, which filed for damages against Microsoft in 2000 for infringing on Lee's patents, according to a report by the Agence France-Presse (AFP).

Now that Microsoft's request has been struck down, P and IB leader Kim Kil-Hae said the company and Lee have a better chance at winning damages in their lawsuit and also in stopping the sale of the version of Office that includes the patented technology, according to a report by the AFP. Lee and P and IB are seeking damages of 70 billion won, or about US$75 million.

However, Microsoft said it did not anticipate any interruption in the sales of Office in Korea, and is positive about its chance in the current infringement case that is still pending.

Lee and P and IB filed suit against Microsoft in 2000 for infringing on Lee's patents for technologies that automatically switch the input mode of Office between the Korean and English languages. That case remains unsettled in an appeals court after Microsoft filed a separate lawsuit attempting to invalidate Lee's patents.

The patent dispute is just one of Microsoft's legal woes in South Korea. In July, a South Korean appeal court ruled against Microsoft in an antitrust case, forcing the company to sell a version of its Windows OS without its media player and instant-messaging programs after finding that their inclusion breached antitrust laws.

An anti-trust case in Europe also has not gone well for Microsoft. In March 2004, the European Commission ruled that Microsoft must sell Windows without media player software in the European Union to compete fairly with rivals there. The ruling also ordered Microsoft to provide information that allows rival server software vendors to design server products that interoperate well with Windows PCs.

Microsoft is still embroiled in its legal battle with the Commission and continues to file documents to prove it is complying with the antitrust ruling. The
the Commission fined Microsoft$357 million in July for failing to comply with the anti-trust order, and could face more fines of up to $3 million per day if it does not meet the Commission's latest deadline to prove compliance.
