You talk about copyrights but in the menus offered to deposit a work there is no reference to the IPI number (international copyright number) and the possibility of putting the PRO to which we are a member? Can you please give me more details.
Since our main clients are Chinese companies, we make more rules based on Chinese copyright law.
The IPI and other institutions you mentioned have not been involved yet, and I will also report your issue to the relevant operation colleagues.
