摘　　要：在专利侵权判断中,我国法院曾适用多余指定原则和改劣实施论。多余指定原则认为,被控侵权物中即使缺少专利权利要求的一个技术特征,如果该特征可以认定为非必要技术特征,仍可以认定构成侵权。改劣实施论认为,被控侵权人故意改变或减少权利要求中的一个技术特征,使被控侵权物在性能和效果上明显劣于专利技术,仍应当适用等同原则认定为构成侵权。最高人民法院在本案判决中,明确了全面覆盖原则,否定了多余指定原则和改劣实施论。In the course of patent infringement judgment,Chinese courts used to apply redundant designation principle and inferior implementation theory.Under redundant designation principle,even if an element of a patent claim is missing in the alleged infringement,if the element can be considered as a nonessential element,it can be considered as infringement.Under inferior implementation theory,if the accused infringer deliberately changes or reduces one of the elements of the claim,so that the accused product is obviously inferior to the patented technology in performance and effect,it still could be considered as infringement under doctrine of equivalents.In the decision of the case,the Supreme Court proposed all elements rule and denied redundant designation principle and inferior implementation theory.
