The estate of the science fiction author Philip K Dick plans to sue Google over its Nexus One brand name for its new mobile phone.

Dick's daughter Isa Dick Hackett said in December she was "shocked and dismayed" over reports that Google had chosen that name. Dick's novel "Do Androids Dream of Electric Sheep?," later filmed as "Blade Runner," featured a bounty hunter tracking down Nexus-6 cyborgs.

The estate of Dick has now sent a letter to Google asking it to cease and desist from using the Nexus name. At the Jan. 5 announcement about the phone, Google said that there was no association with Philip K. Dick and the word was being used based on its definition alone.

The Nexus name was not trademarked by the Dick estate.
