We don’t understand why IPOS refused to insert the 4 priority claims after all of your efforts. Again, we are afraid that this is due to the loss of novelty resulting from the late filing of the patent application in Singapore at your end.
Our client will not be willing to pay the considerable amount of official fees (even though you are really kind to waive your professional fees) for filing the Request for Search and Examination at IPOS. Furthermore, even if the client gets a patent, we are wondering any third party can invalidate his patent based on his own US Patent No. 6,257, 248 that has already be published on Jul 10, 2001 (before the filing date, June 14, 2001, of this patent application).
We need your clarification on the novelty issue as well as the possible invalidation issue.
