First of all, I want to say that this is not a failure in the preliminary examination, but a failure in formal examination, so the Trademark Office issued a notice of rejection. Just submit new and clear stamped materials to them and resubmit. This is the same as reapplying. But if you can get back all the fees paid to him, you can switch to another company, but the easiest thing is to provide this company with clear stamped materials. Now remember to ask them to check if there are any similar trademarks. It has been two months and many trademarks have gone out of the blind period. It is best to search again
