Thailand

Thailand’s Department of Intellectual Property (DIP) has remained open throughout the pandemic, clearing a sizeable backlog and issuing an increasing number of office actions, thanks to the hiring of additional patent examiners. Although overall filing numbers have decreased over the past year, the country remains an attractive market for international corporations. In September 2020, the DIP published the latest draft amendments to the Patent Act, which include preparations for Thailand’s accession to the Hague Agreement.
