What is a Technical Evaluation Report for a utility model?
Because patentability is not substantively examined for a utility model application, there is considerable instability and uncertainty regarding the application’s validity. If a patentee inappropriately exercises such uncertain right, the patent rights may possibly be abused, which may hinder a third person’s research and development. Therefore, a Technical Evaluation Report may be requested to clarify if the said utility model complies with the patentability. It should be noted that the Technical Evaluation Report is simply a reference for exercising the rights to utility model or for technical reference. Those who believe a utility model should not be approved may institute an invalidation action to revoke the said patent.
