I am a little puzzled.
"Apple will likely assert that the patched versions still violate claims 1 and 8 of US Patent No. 5,946,647,"
Aren't you rather assuming that HTC and Google are incapable of coming up with a fix that avoids Apple's patent? Or are you assuming that whatever the fix is Apple will sue whether or not the fix in reality still breaches their patent? The ITC *has* rejected the rest of Cupertino's claims from its original suit, dated March 2010 (a total of nine alleged breaches not upheld by the commission) and it seems to me that as long as the fix is competent there is a reasonable likelihood that HTC will win through. If they do it will be a lot harder for Apple to sue the other OEMs over the same patents.
