Apple's $1bn lawsuit victory over Samsung has been shrinking away since its original award with a significant $380m being wiped off the judgement by the appeals courts. Now it looks like the remaining balance might be thrown out too after the US Patent re-examination process found that the key iPhone patent was invalid and should never have been awarded, thanks in part to prior art from - and here the irony just gets heaped on - Samsung!
FOSS Patents has the details here and they make for interesting reading. Not least because it allowed Apple to process a case which should never have got to a courtroom.
It seems likely that the next stage in this process will be for Samsung to challenge the judgement in the Supreme Court, with what looks, to the untrained eye, like a pretty good case for dismissal.
