I'm pretty certain this is a "patent troll" attempt, and the first time they try to bill any "big player" and get taken to court, it will be thrown out - at leas in the US (see "Supreme Court ruling makes 'obvious' patents harder to defend"). Notice that for now they are only trying to bill people in Singapore under the Singapore patent, so maybe they they already suspect it would be a waste of time to even try to make claims elsewhere? Also, if you read the actual patent application, it takes a very, very liberal reading of it to suggest that any image links to other web sites somehow encroach on that patent; and certainly if they try to claim that aspect as being part of the patent, it is bound to fail, as visual links were made possible by HTML long before the patent application was filed. But I'm no lawyer, so who knows? :rolleyes:
Also, the fact that this story seems to have still not made any of the big international news outlets yet leaves me feeling there's probably not a lot of teeth behind this. But again, I am not a patent lawyer, so don't blame me if I'm wrong! (Did that cover my @$$ sufficiently? :p )
