The text of the draft was submitted t
31、o the Unique Acceptance Procedure and was approved by CENELEC as EN 50090-5-2 on 2003-12-02. This European Standard supersedes R205-009:1996. CENELEC takes no position concerning the evidence, validity and scope of patent rights. Konnex Association as Cooperating Partner to CENELEC confirms that to
32、the extent that the standard contains patents and like rights, the Konnex Associations members are willing to negotiate licenses thereof with applicants throughout the world on fair, reasonable and non-discriminatory terms and conditions.
