(4) As mentioned above, the trademark registrant "陈建勇" is selling the mark online. If client agrees, we may have our investigator approach him to see how much he will be charge for this trademark without revealing the real buyer. If the price is acceptable, client may have the mark purchased and withdraw the non-use cancellation filed. However if the price is unreasonable, we can wait to see the result of non-use cancellation. We suggested filing non-use cancellation before approaching the trademark registrant for assignment is to avoid the trademark registrant to get prepared if he is aware that someone may take action against his registration.
