HP purchased Palm and its webOS operating system in 2010 for $1.2 billion. After trying to sell handsets and tablets using the OS, HP finally gave up and sold it to LG. Among the patents being purchased by Qualcomm are some related buying to iPAQ and Bitphone. The former was the name of a line of PDAs and Pocket PC phones made by HP. The latter is software designed for MDM services.
It isn't immediately clear exactly how Qualcomm plans on using these patents, but we're sure that some further news will be coming soon.
