In
February 2011, CN-KnowHow, appointed by our Japanese client; Mr Satou,
filed a request for invalidation for an utility model patent (Patent
Number:ZL200820222527.9) owned by Shanxi Caihong Electronics Glass
Co.,Ltd with the title of "ELECTRODE MELTING TANK FOR OPTICAL GLASS”.
Upon appointment,
experienced patent attorneys Mr Han Guosheng and Ms Wang Ying from our
company were put in charge for handling this invalidation case. They
prepared carefully the written documents after obtaining up to 10
references which could have undermined the patentability of the
concerning patent. On 21 June 2011, they both attended oral proceedings
before the patent re-examination board of State Intellectual Property
Office (SIPO). The patent re-examination board of SIPO made invalidation
decision on 01 September 2011, according to which the whole of the
patent right was ruled invalid.
In
the past few years, while attaching great importance on the domestic
patent invalidation cases, CN-KnowHow has also trained many experienced
talents specializing in handling foreign-related invalidation and
litigation cases, with excellent language skill. Up until now, we won
and achieved favourable results in almost every foreign related
invalidation case we handled, regardless of being the requesting or the
defending party.
