| Single Parameter Range and Whole Parameter Range, and Assessment of Novelty |
| |
| 摘 要： | It is a relatively common phenomenon to limit technical features with parameter range in patent claims. It is argued in this article that the parameter range should be distinctly divided into single parameter range and whole parameter range depending on the different mode and function of limitation. Each and every parameter in a single parameter range may independently achieve a technical effect, and limit one embodiment alone; while a single parameter in the whole parameter range cannot independently achieve any technical effect, and the set of parameters as a whole within the parameter range limit a technical feature. Discrimination between the single parameter range and the whole parameter range has a bearing on the assessment of novelty and inventiveness. Owing to the absence of such discrimination of parameter range, the provisions of the current Guidelines for Examination on novelty and inventiveness of the claims relating to parameter range are not applicable to the circumstance of whole parameter range.
