 Patent Reexamination

No.222 Reexamination Decision of the Chinese Patent Reexamination Board (introduce)

The present decision was made by the Chinese Patent Reexamination Board. It relates to the patent reexamination procedure of a patent application, which was authorized by Toshiba Corporation and handed by the agent of Our Company to file with the Chinese Patent Office for patent for invention in 1985, and was rejected by the Examiner of the Office on lack of inventiveness. Toshiba ordered the agent of Our Company to file the reexamination request in 1987. Because this case relates to the judgment about the inventiveness, and it is a method invention (“Method for Manufacturing Fluorescent Screen of CRT”), it is rather difficult to make the decision. With the efforts of the agent by filing three times of arguments with the Board and discussing with the Examiners of the Board many times, the Board finally supported the reexamination request, and announced that the present invention possesses inventiveness. The reject decision was revoked, and the present application was granted as a patent for invention.
