委托代理机构办理的国际知识产权业务，各国官方机构仅会与申请人或权利人授权的代理人联系与沟通。假如您在业务办理期间收到任何第三方机构的索费材料，如商业发票(INVOICE)等，或是其他看似官方机构文件的材料，如WIPO, OHIM通知书等，请一定要谨慎，切勿轻易付款。

These invoices generally request a payment for registering your application, or offer another extraneous service unrelated to the maintenance or prosecution of your IP rights. If you are not sure about the ground of the invoice, contact us .

如您收到上述索费文件无法认定其真实性，您可以与我们或是您委托的其他代理机构联系，由专业人员协助您处理。
