Intellectual Ventures and RPX Corporation working together to snap up the imaging IP for $525 million. The former is an agent for Apple’s interests, among others, while RPX represents Google.

RIM, Apple and Google, are among the 12 patent licensees participating in the deal, according to a court filing. Under the terms, Intellectual Ventures will make a portion of the payment, with the rest coming from the licensees.

Facebook Inc., Amazon.com Inc. and Microsoft Corp. (MSFT) also are part of the group, the court filing shows, along with Samsung Electronics Co., Adobe Systems Inc., Fujifilm Holdings Corp., Huawei Technologies Co., HTC Corp. and Shutterfly Inc. The auctioned patents were previously estimated to be worth as much as $2.6 billion.

“This is a fraction of our overall patent portfolio,” said Chris Veronda, a spokesman for Rochester, New York-based Kodak. “We retain ownership of about 9,600 other patents for our ongoing businesses.”

Partnerships are common in patent sales because they allow competitors to neutralize potential infringement litigation.
