Among the co-sponsors of the OPEN Act are many of the most vocal opponents of SOPA, including Representatives Zoe Lofgren and Anna Eshoo, both California Democrats; Representative Jason Chaffetz, a Utah Republican; and Representative Jim Sensenbrenner, a Wisconsin Republican.
Also sponsoring the bill is Representative Jim Langevin, a Rhode Island Democrat and activist for improved cybersecurity practices.
SOPA would allow the U.S. government and copyright holders to "filter the Internet," while the OPEN Act represents a compromise that will crack down on piracy, Langevin said in a statement.
"Instead of trying to mitigate security, economic, and Internet freedom concerns with broad, over-reaching technical solutions, I support proposals like this one that seek a middle ground for curbing online piracy while protecting American jobs and innovative technologies that have allowed us to remain the world leader online," he added.
The Consumer Electronics Association, a vocal opponent of SOPA, applauded Issa and the other sponsors for introducing the OPEN Act.
