In
February 2011, CN-KnowHow, appointed by our Japanese client Mr Satou,
filed a request for invalidation for an Utility model patent (Patent
Number:200810018344.X) owned by Shanxi Caihong Electronics Glass
Co.,Ltd with the title of "Temperature equilibrium apparatus and method
for flat panel display glass substrate molding”.
After
the appointment, experienced patent attorneys from our company were
put in charge of the handling of this invalidation case, After
conducted detailed and careful searching, a total of nine reference
documents were obtained including patent documents, books, etc. , which
can destroy the inventive step of the concerning patent. Written
materials for the request for invalidation were prepared meticulously,
after multiple written and telephone communications with the client.
After
holding the oral proceeding on 21 June 2011, The patent re-examination
board of SIPO has made the invalidation decision on 23 September 2011,
according to which the whole of the concerning patent right is ruled
to be invalid. It was stated in the decision that the claims of the
concerning patent did not possess prominent substantive feature when
compared to prior art, therefore the invention did not possess
inventiveness pursuant to paragraph3, article 22 of the patent law.
