專利權利要求被宣告部分無效情形下的侵權判定－－侵害“雙螺旋榨油機”實用新型專利權糾紛案評析

The Determination of Patent Infringement When the Patent Found to be Partially Invalid

獨立權利要求確定了專利權的最大保護範圍，從屬權利要求的保護範圍較小且在獨立權利要求的保護範圍之內。獨立權利要求被宣告無效後，其直接從屬的權利要求就上升成為了獨立權利要求。在專利權的權利要求被宣告部分無效的情況下，應當以每一項被維持有效的權利要求記載的技術特徵，與其引用的權利要求記載的技術特徵，共同確定專利權的保護範圍，不能因所引用的權利要求無效而限制維持有效的權利要求的保護範圍。

Independent claim confirms the maximum rang of the protection, while dependent claim at a smaller rang of protection and in the scope of protection of independent claim. After independent claim being declared null and void, its dependent claim becomes independent claim. In the case of being declared invalid, the scope of protection should be based on each technical feature of the records which is maintained effective and referred, cannot limit the scope of the protection of maintain effective claim because of its invalid reference.
