I find it interesting, of course, since DNS is not the only address translation required. Before reaching the end server (and the patent says, "Central computer"), an ARP translation will be required as well to translate an IP address into a MAC address for transit across the physical+datalink layers of IP.
The funny thing is that this patent was supposedly dead from prior art from what we've all heard, and it didn't even get far enough. Basically, the judge dismissed them for grossly misinterpreting the patent, never mind that it would likely have been rendered invalid by prior art had they even made it that far. I hope BT had to pay court costs.

Actually, the judge did mention several additional levels of translation required. He mentioned that the web server needs to resolve the relative address in the the URL into a local address by looking up the base directory in a configuration file, and then needs to ask the OS to find the actual physical track and sector where the file is located. (Apparently the BT people specifically said that a complete address would have to include track and sector information!) He didn't even get into the idea that in many cases the data sent out isn't even a file at all, but is generated dynamically by the server.

Since it's apparently necessary for all free developers to know the u.s. patent system well in order to more effectively undermine it, here's a good place to start. Hats off to this judge for presenting the material in a clear, almost tutorial manner.
It's essential to be able to read patent claims the way a judge does. It's not as hard as it first appears - remember, the Judge has just as much trouble with technical aspects as we have with the patent legalese. One thing to keep in mind is that it's the claims that matter, and these are generally a fairly small part of the patent.
Once you figure out what the claims mean, it's a lot easier to go hunting prior art or find a workaround.
Of course I'm not suggesting that all developers have to stop coding now and become patent lawyers, but we do need a lot more eyeballs on these things to help counterbalance the prevailing insanity. Besides, undermining patents is an interesting sport in and of itself.</ramble>

Indeed, Ted is the one who coined and popularized the terms "Hypertext" and "Hyperlink".
What bugs me is that, as I read it, the judge's decisions about "central computer", "blocks of data", and "complete address" are all wrong. The patent should have applied to the Internet (by the doctrine of equivalences) and should have been struck due to the prior art.
But then again, IMHO patents on "doing X with a computer when people are already doing X by hand" should be unpatentable. (A generic patent on simulating human workflow would have been patentable shortly after the inventionn of the digital computer, but it's far too late for that now.)

In effect, this is exactly what happened. If you read the judgement right through, you'll see that 'central computer', 'blocks of data' etc. were made to have very narrow, specific meanings by BT, in an attempt to get the patent granted in the first place, despite the wealth of prior art.
Crucially, BT limited 'complete address' during their patent application to specifically include the track and sector on the disk where the next page should come from, because 'virtual addresses' (using filenames or other additional 'lookup data') had already been described and used elsewhere.
Without being able to show infringement of this and other features, they didn't stand a chance. Of course, the lawyers made a bunch of $$$, and we all pay for that somewhere...

Had it not been used to avoid conflict with prior art perhaps it could have been contrued in the wider sense.

Me too. More in a moment. (I think we're agreeing, but in different words.)
Look, the reason why congress established the patent office in the first place was to "foster innovation". [etc.]
Right.
And if there's something significantly innovative about the WAY you got the computer to pass the turing test, or dance a ballet, that should be patentable.
"Innovative" includes figuring out and replicating the function of how people do something that's not well-understood already - like dancing or "thinking".
But "innovative" does NOT include taking, for instance, a well-understood business process (i.e. "Record the customer's billing and delivery information. Then when he orders something, don't bother asking for it again - just deliver it and bill him.") and automating it in a straightforward way (the "one-click purchase" patent).
Once the general case of automating a well-known process is invented, automating any particular one is "obvious to a person versed in the art" unless there's something that is NOT well known and is NON-obvious about that particular process.
Further, there is a specific exemption to the patenting process for "mathematical algorithms" - and mathematics includes boolean logic, factorization, etc. This brings into question the patentability of "inventions" where the core of the invention is a new way to perform a computation, rather than, say, a new way to use a computation to solve a real-world problem.
But regarding the promotion of innovation: Patents are a two-edged sword. They advance innovation by rewarding the firstcomer but retard innovation by blocking the participation of additional innovators. IMHO when it comes to software the retarding effect FAR outweighs any benefit from the reward.
Copyrights, on the other hand, seem to be an appropriate level of protection. The prevent verbatim copying but allow reverse-engineering. This gives originators a couple years lead in time-to-market (in a VERY-fast moving industry with significant first-mover advantage) and requires that their competitors make a comparable development investment rather simply distributing verbatim copies of someone else's work. But it doesn't create a "MINE!"-field where the inventor of a tiny piece of the puzzle locks out all other players for a couple decades.
Commercial software became a lucrative industry while neither copyright nor patents could be had for software, and exploded into the multibillion-dollar range with copyrights but not patents. IMHO that alone shows that nothing more than copyrights are necessary. And the current collapse of hi-tek in the presence of software and business-practice patents, DMCA, and a host of other intellectual-"property" restrictions hints that the additional restrictions are a net impediment.

The interface allows for accessing the data on the system by chunks. The users somehow selects a menu or a link when they want to access the next bit.
The court comprehensively dismissed all parts of BT's infringement claims.First the Internet is not a central system, second a central database is not accessed (the judge writes that the Internet is in fact the very antithesis of a central database), next the data on the Internet is not in the form of blocks: HTML is far more flexible than what the BT patent describes, and finally the concept of hyperlink is far more advanced than what BT described in its patent (basically a `give me the next bit' button).
At some point during the trial, BT's expert tried to submit made up web pages that conformed to what the BT patent was describing. The judge found that totally unconvincing, writing `a device does not infringe because it can be made to infringe'.

I am almost certain that these people did not read the decision carefully, because it really does completely demolish any idea that infringement *of this patent as granted* ocurred. The prior art about hyperlinks etc. was really besides the point because the BT patent did not end up describing hyperlinks anyway. Really, this ruling is probably better and fairer than declaring the patent invalid, because, as far as I can tell, there really was a novel invention that the patent does describe...and which nobody is especially likely to infringe on since we just don't go around providing button interfaces to access specific hard disk track/sector data on centralized computer systems.
