Practice > Trademark

Our IP lawyers and attorneys have represented foreign and Thai companies on IP prosecution and IP litigation in Thailand and abroad.

Intellectual property is invaluable for all kinds of industries, especially in this digital era.  Sources of competitiveness have been shifting to knowledge-based factors of production.  In this new knowledge-based economy, intangible assets, including inventions, designs, innovative ideas, branding, and know-how, have become central business assets.  Creating, protecting, utilizing and enforcing your intellectual property rights are crucial to the success of your business.

With our in-depth knowledge of the Thai economy and the clients’ industries, and our understanding of local practices, we strive to make our advice practical and valuable to the client. Our IP clients include corporate clients in a variety of industries, including automobile, film, entertainment, telecommunications, information technology, food, drug, beverages, healthcare, cosmetics, clothing, construction, retail and wholesale service.  We work with IP law firms in over 160 countries on registering and enforcing IP rights of our clients.  Our services include trademark and patent search, registration, opposition, appeal, cancellation, renewal, assignment, license, recovery, anti-counterfeiting, investigation and litigation.
