As reported by ENgadget:
Remember [the lawsuit] between Apple and Cisco over the "iPhone" trademark? ... [Now it's a large] Taiwan-national with Microsoft in its pocket: HTC, and their HTC Touch [versus] Apple, and their iPod touch.
Peter Chou, CEO & president of HTC, [reminded] the press that HTC has registered "Touch" as a worldwide trademark and is "proud to share the same vision as Apple over touch screen functions." While he wouldn't comment on whether HTC would take legal action against Apple, HTC's Marketing Manager Ching-hung Wang was happy to talk around the issue by noting Apple's and Cisco's ability to "reach a mutually satisfactory agreement" before, while footnoting the need for "further observation" around the "Touch" trademark rights question. Translated: Hey Apple, we think HTC is waiting for your call. Maybe you should make it a party line too so that Creative can bring their Zen Touch?
I'd find it hard to speak to anyone named Chin Hung Wang and not think of Men In Black II and the Ballchinian.
I doubt HTC will make much of a deal about this because it appears as if they ripped off a few "interface elements" of the iPhone.
