Aha! This will be interesting now. HTC is sue-ing Apple using patents it bought from Google, which Google got from Motorola.
Everyone in the industry knew that Google is stocking up patent ammunition to lead it's counter-attack against Apple & Microsoft. This move also redeems Google's lost credibility among Android licensees (handset manufacturers like HTC and Samsung) when it acquired Motorola. I would expect very soon to hear news of Samsung fighting back the injunctions against Galaxy tabs with similar Google-supplied patents. A proxy patent war has started. Clash of the titans, indeed!
