Its reasons for invalidation announcement covered Articles 22, 26, and 33 of the patent law and Article 20 of the implementing regulations of the patent law and other articles. Entrusted by Shenzhen ChinaIC Semiconductor Co., Ltd. (the patentee), China Truer IP agented the invalidation proceeding. Wang Zhenyu and Zhao Yefu, patent agents of China Truer IP, responded to this invalidation announcement with written defenses and participated in the oral proceeding of the reexamination board. Patent agents of China Truer IP made an adequate and powerful defense on all the invalidation reasons of the applicant in the written defense and oral hearing debate. They succeeded in maintaining validity for all the claims of this patent and further maintained and consolidated the rights and interests of the patentee.
