More than 400 organizations have publicly expressed support of the contentious Stop Online Piracy Act (SOPA), or the passage of other similar anti-piracy legislation. Here’s the complete list.

By Andrew Couts:

More than 400 organizations have publicly expressed support of the contentious Stop Online Piracy Act (SOPA), or the passage of other similar anti-piracy legislation. Here’s the complete list.

With the next House Judiciary Committee markup hearing delayed until “early next year,” opponents of the Stop Online Piracy Act (SOPA) and the Protect IP Act (PIPA) are looking for more ways to fight back against these contentious pieces of legislation, while they still have a chance.

The anti-SOPA crowd includes everyone from Internet giants like Google, Facebook, eBay, Wikipedia, Mozilla and Yahoo! to The New York Times, the Stanford Law Review and even the very people who created the Internet in the first place. Experts say SOPA and PIPA would not only stifle free speech by allowing widespread censorship (in the name of copyright protection), but could castrate innovation, destroy the open Internet, and disrupt the very foundation upon which the Internet was built, the domain name system. (See a comprehensive list of SOPA opponents here.)

From the pro-SOPA side, we’ve heard much from organizations like the Motion Picture Association of America (MPAA), the Recording Industry Association of America (RIAA) and the US Chamber of Commerce — not to mention politicians, like Rep. Lamar Smith (R-TX), the chief sponsor of SOPA, and the chairman of the Judiciary Committee. But far too little light has shone on the hundreds of organizations that continue to support SOPA, despite the staggering dangers it holds for the Internet as we know it.

Below is a list of 439 corporations, unions, law firms and other groups that have explicitly expressed their support of SOPA, or similar anti-piracy legislation. This list is derived from two sources: the official list (pdf) of SOPA supporters from the Judiciary Committee’s website, and a letter (pdf) addressed to Congress from the Global Intellectual Property Center, which is an affiliate of the US Chamber of Commerce.

Some have begun organizing a mass boycott of these organizations, and a list (Google Doc) of contact information for each is currently in the works. We’re not advocating any specific action, but we do think it is important for people to understand who is for and against SOPA and PIPA; if passed, either of these bills will fundamentally change the online world, whether you think that’s a good idea or not.

UPDATE: We have learned that Petzl America has explicitly stated that while it supports greater protections of intellectual property, and signed the Global Intellectual Property Center letter to Congress (along with 401 other companies on this list), it “does not support SOPA or the Protect IP Act,” or any other legislation that will “harm the freedom of the Internet.” We have taken their name off the list.

UPDATE 2: All of the law firms that originally appeared on the Judiciary Committee’s list of SOPA supporters have been removed. We have removed them from the list below. They include:

BakerHostetler LLP
Cowan, DeBaets, Abrahams & Sheppard LLP
Cowan, Liebowitz & Latman, P.C.
Davis Wright Tremaine LLP
Irell & Manella LLP
Jenner & Block LLP
Kelley Drye & Warren LLP
Kendall Brill & Klieger LLP
Kinsella Weitzman Iser Kump & Aldisert LLP
Lathrop & Gage LLP
Loeb & Loeb LLP
Mitchell Silberberge & Knupp LLP
Morrison & Foerster LLP
Patterson Belknap Webb & Tyler LLP
Phillips Nizer LLP
Proskauer Rose LLP
Robins, Kaplan, Miller & Ciresi LLP
Shearman & Sterling LLP
Simpson Thacher & Bartlett LLP
Skadden, Arps, Slate Meagher & Flom LLP
White & Case LLP

It has not yet been officially explained why these firms have been pulled off the list. At least one firm, however, Davis Write Tremaine LLP, has said that it does not support SOPA, but two of its lawyers privately support the bill.
