As of this writing, there are\u00a0<a href=\"https:\/\/www.chinaiplawupdate.com\/2021\/07\/first-generic-declarations-published-on-chinas-new-patent-linkage-system\/\" target=\"_blank\" rel=\"noopener\">four published declarations<\/a>. The generic drug applicant must also directly notify the holder via email although no deadline is provided.\u00a0 Accordingly, holders should monitor the CDE platform regularly as holders must file either a request for adjudication or litigation within 45 days of publication.<\/p>\n<h2><strong>Dispute Resolution<\/strong><\/h2>\n<p>Within 45 days of publication of the generic\u2019s application the holder must file a complaint with the Beijing Intellectual Property Court or a request for administrative adjudication with the CNIPA. (Note that while the Implementation Measures specify a holder may object to all 4 types of declarations, there is some debate in the patent community if a holder can only object to a Class 4 declaration.) Within 15 days of receiving a Notice of Acceptance, the holder must notify the CDE with a copy of the same or a Notice of Docket and notify the generic drug applicant.\u00a0 The CDE will then impose a 9-month moratorium on marketing authorization approval but will not stop the evaluation of the generic\u2019s application. Note that generics of biologics and TCMs are excluded from the 9-month moratorium. Accordingly, if no decision is reached within 9 months, the generic\u2019s application could be approved shortly thereafter making the speed of the dispute resolution essential.<\/p>\n<h2><strong>Choice of Venue<\/strong><\/h2>\n<p>Holders may either litigate at the Beijing IP Court or administratively adjudicate at the CNIPA. With patent litigation at the Beijing IP Court taking\u00a0<a href=\"http:\/\/bjgy.chinacourt.gov.cn\/article\/detail\/2021\/04\/id\/5989576.shtml\" target=\"_blank\" rel=\"noopener\">274.5 days on average<\/a>, adjudication at CNIPA may be preferable as it may be potentially faster for several reasons. Unlike litigation, oral hearings are not automatic in CNIPA adjudications thereby reducing time to a decision. Also, historically, administrative actions at CNIPA have tended to be faster than litigation (e.g., patent invalidations take an\u00a0<a href=\"https:\/\/www.cnipa.gov.cn\/col\/col2616\/index.html\" target=\"_blank\" rel=\"noopener\">average of 5.9 months<\/a>). Formalities tend to be less stringent at CNIPA, such as with powers of attorney, as compared to the Beijing IP Court thereby reducing potential delays and leading to a quicker decision.\u00a0 Finally, CNIPA may feel bound to issue a decision within the 9-month moratorium as CNIPA jointly released the Implementation Measures with the NMPA in contrast to the court system which may not feel any obligation to meet a deadline imposed by a different government division.<\/p>\n<p>Another reason to select CNIPA for adjudication in favor over litigation at the Beijing IP Court is that the CNIPA does not provide for the litigation defenses of prior use or existing technology in administrative adjudication making a marketing authorization holder win potentially more likely at CNIPA. (Article 7 of the Provisions state that a generic can use the defenses of Articles 67 and 75.2 of the Patent Law. In contrast, the Administrative Adjudication Measures do not list these defenses implying they are not available.)<\/p>\n<h2><strong>Be Prepared to Move Quickly<\/strong><\/h2>\n<p>Accordingly, due to the short moratorium and other deadlines, marketing authorization holders should closely monitor generic drug applications and be prepared in advance to litigate or adjudicate quickly when necessary.<\/p>\n","protected":false},"excerpt":{"rendered":"<p class=\"excerpt\">This article originally appeared in IP Watchdog here.
