专利先用权抗辩的成立条件——北京英特莱技术公司与深圳市蓝盾实业有限公司北京分公司等侵害发明专利权纠纷案

Conditions for the Establishment of Prior User Right

成立先用权抗辩的起算日期是专利申请日。判断相关产品是否为相同产品时也包括等同的情形。以合法方式从专利权人处获知技术方案的,仍可以成立先用权抗辩。对于"原有范围"应宽松化解释,在符合市场生产规律的情况下,可以对原有产品类型进行适当地扩展。在第三人的技术来源合法且制造者的先用权成立的前提下,第三人使用或销售先使用者制造的专利产品的,可以主张先用权抗辩。

The date of commencement of prior user right defense shall be the date of patent application. When judging whether the relevant product is the same product, the equivalent situation is also included.Where a technical scheme is obtained by lawful means from the patentee, the prior user right defense may still be established. The "original scope" should be loosely interpreted, and the original product type can be appropriately expanded in line with the production law of the market. Where a third party USES or sells a patented product manufactured by a prior user, it may claim a defense of the prior use right provided that the technical source of the third party is lawful and the prior use right of the manufacturer is established.
