After
the previous failed attempt in requesting for invalidation, regarding
an invention patent (Patent No.: ZL 200410060988.7) titled "A Compound
Chinese Medicine for Treating Gynecological Disease and Its Preparation
Method", which is owned by Wuzhou Pharmaceutical Group, the same
pharmaceutical company from Qin Huangdao, Hebei province filed another
request for invalidation for the second time on 31 May 2011. Entrusted
again by the patent right owner, patent attorneys from CN-KnowHow
conducted written response with regard to the concerning patent and
attended oral proceedings before the patent re-examination board of the
State Intellectual Property Office (SIPO). The patent re-examination
board of SIPO made the examination decisions for this case on 28
November 2011, in which the whole of concerning patent right was again
ruled to be valid.
Previously, CN-KnowHow
has already won all of the four invalidation cases representing Wuzhou
Pharmaceutical Group. Therefore, CN-KnowHow has managed to maintain our
perfect record in all five invalidation cases for Wuzhou Pharmaceutical
Group.
