The intellectual property chief expects the Ministry of Digital Economy and Society's bill to tackle online sales of pirate products to take effect next year.
Thosapone Dansuputra, acting director-general of the Intellectual Property Department, said on Wednesday that drafting of the ministry's new computer act was well underway.
"It will include provisions for legal action against violators of intellectual property rights on the internet, and the power to stop the violation at once. It is expected to take effect next year," he said.
Mr Thosapone said there had been a lot of complaints about intellectual piracy using social media.
Sales of pirate products were common on Facebook and at flea markets. The level of intellectual property violation could be bigger than the illegal copying of movies in theatres, he said.
The drafting of legislation to tackle internet-based piracy was in response to a request from the United States, Mr Thosapone said.
