Apple and Google, bitter rivals in smartphone technology, have joined up to make a combined bid for a bundle of patents offered by photography pioneer Kodak, according to a published report.

Bloomberg News reported Saturday that Apple Inc. and Google Inc. have abandoned competing bids for the portfolio to offer a combined $500 million. The sum is the minimum Kodak can sell the patents for and still get an $830 million loan that's crucial to getting the company out of bankruptcy.

Apple and Google declined to comment on the report. A Kodak representative did not immediately respond to a request for comment.

Kodak filed for Chapter 11 bankruptcy protection in January after struggling to adapt to the world of digital photography.
