A group of law professors has urged the US Congress to reject the PROTECT-IP Act, which was broadly welcomed by trademark owners in May. The act “may represent the biggest threat to the Internet in its history”, write the opponents, who include Creative Commons co-founder Lawrence Lessig, and trademark bloggers Eric Goldman and Rebecca Tushnet. Meanwhile, INTA has issued a statement in support of the proposed law.
