Welcome to CPTO!

Protecting your international property rights at home and abroad can be a daunting task.  It is important to work with professionals who are erudite and passionate about trademark, patents, science, and technology and understand your business. For this reason, we recommend you to use CPTO as your intellectual property office in China. Our staff at CPTO is dedicated to helping you sort through the process, providing you with the information and guidance to ensure that your application goes as smoothly as possible.

Our staff has been dealing with trademark applications and laws from the beginning, which corresponds to decades of experience in trademark and patent law. We can provide as much support that meets your needs – from designing trademarks and running patent & trademark searches to simply submitting your applications to SIPO. Protecting your intellectual property is important to us. Put your business in the best hands – Ours.

Please feel free to explore our website and take advantage of our free trademark and patent search. If you have any questions, take a look at our Frequently Asked Questions page, or feel free to contact us at sophia@cpto.cn.
