About Me

You can call me Laoliu (Liu Junwei). I’m a China trademark specialist, focusing on global clients’ brand protection in China since 2012. I run my own intellectual property agency in China — Tianjin Puyi Intellectual Property Agency Co., Ltd., short for PUYIZHICHAN, with our official website: https://en.puyizhichan.com. My core services cover all types of Chinese trademark agency services, including trademark registration, renewal, name and address changes, office action appeals, and defensive trademark filing across mainland China. Feel free to contact me for any inquiries about Chinese trademark matters or a free quotation, with no obligation to purchase.
