Junzhiquan has recently received a winning judgment in the first instance of administrative litigation and the State Intellectual Property Office has made another decision to maintain the validity of the patent right.

A basic patent of PixArt Technology related to optical navigation chips has been invalidated. In the previous invalidation case, Junzhiquan's team actively responded with its rich experience and strong professional ability, so that the State Intellectual Property Office made a favorable conclusion in the examination decision to maintain the validity of the patent right on the basis of amending the text. In response to this conclusion, the requester strengthened its efforts to file an administrative lawsuit, and on the other hand, strengthened the evidence to file a new request for invalidation. With in-depth research and sufficient preparation, the claimants of the requester were successfully resolved in both proceedings, and finally won successively in both proceedings, successfully defending the patent rights of the basic patent.
