Aptina and Sony cross-license their camera patents, Nikon smiles
 

Sometimes, it's the behind-the-scenes deals that matter the most. See Aptina's newly signed patent cross-licensing agreement with Sony as an example: the pact lets the two imaging veterans use each other's know-how in camera sensors for everything from dedicated cameras through to smartphones and TVs. We know customers of both companies will be glad to see technology spreading beyond corporate borders, but we have a feeling that Nikon will be the happiest. When Nikon is using Aptina sensors in its 1 series mirrorless cameras and Sony sensors in its DSLRs, it's likely to reap the benefits, regardless of which sensor maker got the better deal.
