Thailand's rapidly increasing economy and the consequent industrialization has led to the development of advance technolgy that is considered to be of high importance and needs to be protected by trademarks, patents, or copyrights.

Protecting the products with the brandname and marks not only translates goodwill, but also marks the quality and reputation of the product as well as the product owner. IPR infringement and counterfeiting undermines not only this but also the whole concept of R&D. Furthermore, the imported items from other countries are also vulnerable to these risks, however, the fact is that foreign intellectual property rights are not always enforceable in Thailand. C7Legal guarantees a complete protection of your intellectual property.

The Department of Intellectual Property (DIP), a part of the Ministry of Commerce, is a responsible authority in Thailand for IPR policies.
