美国最高法院驳回艾锐势公司针对金杜客户ChanBond的专利有效性复审申请
By King & Wood
项目团队：Mark S. Raskin Robert Whitman Andrea Pacelli 2020年4月27日，美国最高法院驳回了艾锐势公司提出的5项针对金杜客户ChanBond, LLC（“ChanBond”）在美专利有效性的上诉裁决复审申请。该裁定宣告ChanBond最终获得胜诉，为针对ChanBond的知识产权无效性案件画上句号。（英文版请下滑查看） ChanBond在通过有线网络提供高速互联网服务方面拥有多项核心专利。2015年，ChanBond对多家有线网络设备商提起专利侵权诉讼。此后不久，美国专利及商标局共收到9项有关质疑ChanBond专利有效性的双方复审（IPR）请求。其中绝大部分请求均未成功，涉诉大部分权利要求仍维持其有效性。2018年，艾锐势公司（ARRIS International PLC，一家有线设备供应商）另提出5项双方复审（IPR）请求，对相同权利要求的有效性提出异议。美国专利审查与上诉委员会（PTAB）驳回该等请求，认定艾锐势公司与相关诉讼的被告有共同利益关系，这样考虑对该等被告适用的一年法定时限，艾锐势公司不能申请这些附加的双方复审请求。当艾锐势公司试图就PTAB的裁决向美国联邦巡回上诉法院提出上诉时，ChanBond以缺乏上诉管辖权为由向法院动议驳回该上诉，法院批准了ChanBond的动议，上诉被驳回。最终，艾锐势公司向美国最高法院提出再审请求。 美国最高法院驳回艾锐势公司再审申请的裁定使得PTAB的裁决成为最终裁决，清除了ChanBond专利维权道路上的最后障碍。本案定于2020年8月开庭，金杜纽约专利团队全程代理ChanBond，金杜团队负责人为合伙人Mark Raskin, Robert Whitman 和顾问Andrea Pacelli。 United States Supreme Court Denies Petition for Certiorari Against KWM Client ChanBond, LLC…
