SIPO Rejects Microsoft Petition in ZhengMa Case

China Youth Daily, 4/24/08

The State Intellectual Property Office (SIPO)'s Patent Reexamination Board recently moved to reject Microsoft's petition in the case of royalties owed for the ZhengMa Chinese input method, and to uphold the validity of Patent #89108851.2 for the technology. If Microsoft should choose to appeal, it may do so in the Beijing No.1 Intermediate People's Court within three months.

On April 23, ZhongYi Electronics, the holder of the patent, brought suit against Microsoft for patent infringement in the Beijing No.1 Intermediate People's Court, charging that the company had violated its patent on ZhengMa as well as its authorship rights to the software and other legal interests.
