Patent invalidation request about "Ring bell (helicopter)" by us is successful

In 2014, we are consigned by the the party concerned named Lixi to file patent invalidation request about design patent(Number: ZL2201330595019.1, hereinafter called “the involved patent”) which is licensed and announced on March 12, 2014 by SIPO.

After understanding the involved patent, we get some important evidences through searching and analyzing the existing technology, one of which is published previously online. When compared with the involved patent, we find that they are very similar in the outline and picture, which is important evidence in this patent invalidation case.

On October 11, 2014, Patent Reexamination Board of SIPO sendt notification on the oral hearing to both parties concerned and decided to hear the request for invalidation orally on December 16, 2014. Integrated the collegial made by the hearing and collegiate panel, the PRB finally announces that the involved patent rights is totally invalid.

It is mainly based on that the main design body is based on the shape when compare the involved patent with the design in the evidence. When both deigns are the same basically which shape are both helicopter, other differences are little nuances partyly which is not easy to find. They are the same essentially, which doesn’t meet the Second pary of 23th rule of China Patent Law, so our patent invalidation request win.
