Hi Supot, PTT has 3 applications for registration of trademark 'CAFE AMAZON' in Vietnam pending. The trademark agents of PTT are VCCI-IP Co. Ltd (1 application) and INVESTPRO & Associates (2 applications). Two of the applications were filed in 2009 and one in 2015. I suspect that the 2009 applications must be the ones that have met with opposition and that must be why they have not been registered as yet. In order to understand the root cause(s) of the opposition, we must be able to take over the conduct of the applications from the current agents, INVESPRO, and review the files, etc. Can you please let me know if we are to represent PTT in place of INVESPRO and/or VCCI-IP Co Ltd.?
