U.S. Navy Patents the Firewall?
Krishna Dagli writes to mention a post by Bruce Schneier on his site indicating that the U.S. Navy may be patenting the Firewall. Whether or not it is their intention to do so is unclear. From the patent description: "In a communication system having a plurality of networks, a method of achieving network separation between first and second networks is described. First and second networks with respective first and second degrees of trust are defined, the first degree of trust being higher than the second degree of trust. Communication between the first and second networks is enabled via a network interface system having a protocol stack, the protocol stack implemented by the network interface system in an application layer."
I was going to make a "first post", but I think I read the Army is patenting that. Part of their Military Initiative to kill first, ask questions later.

Maybe it's a sad attempt to prove that they're on the cutting edge of technology by patenting some newfangled idea that the rest of us have been using for years? I guess they probably have some catching up to do since EDS has been "working" on their IT infrastructure for years (That's why their stock price fell by half and never recovered don't you know? Well that and lying about the revenues that were coming in from it...)

The US government might actually be entitled to many internet patents, as all or most of the technology behind the (early) internet was financed with U.S. tax payer money. Which, in a democratic country, should (but not necessarily does) mean that those patents are in the public domain.

isn't the US Government not allowed to have any IP rights?
IP = Intellectual Property
Instinctively, I hate the notion of the government patenting anything. It might be because it seems ridiculous that anything the taxpayers paid for should be made unavailable to them. But... I can't find anything in the constitution that makes this abhorent practice illegal or unjustified. My reaction seems motivated by civic virtue rather than a legal basis.
Does anyone know of a solid legal reason that the government shouldn't be able to obtain patents?
I can't wait to see how they deliver the cease and desist orders.

I'm going to patent old jokes. Just so I don't have to read that every time a patent story comes up on Slashdot.
Government's view of the economy: If it moves, tax it. If it keeps moving,regulate it. If it stops moving, subsidize it.
Actually most of the time, the government does not seize patents. Not that they don't have the ability to, or that perhaps they don't just go ahead and infringe on them sometimes, but the military spends a lot of money buying stuff from contractors/vendors every year, because the vendor has a patent on stuff. If we were in the middle of World War III, the situation might be slightly different.
So if someone in the Navy really did have a novel idea, it's not hard to imagine that they might want to get it patented, just as a defensive measure.
My big question is: if the government patents something, wouldn't the invention automatically be in the public domain, provided that it wasn't classified? Normally all products produced by government employees in the course of their jobs are in the public domain, so I would think that a patent held by the Navy would be impossible to use aggressively.
In that situation -- assuming that's true, and the Navy can't collect royalties -- then having the Navy (or other government agencies) patent stuff might be a very good idea. For the small taxpayer expense that it takes to file and maintain the patent, the country might be saved millions of dollars a year of royalties and litigation costs.

The Holy Grail when I worked with military networks (admittedly 10 years ago) was "multilevel security" which could enable a "top secret" and "secret" network to coexist and share data in a very controlled way. Information can go up, but never down. The hard part is how do you receive mail or do other things which require a two-way protocol? We built boxes which could sit in the middle and could pass messages. This appears to be a more advanced version of that.
intellectual property lawyers will fight wars in courtrooms.
Countries possessing patents of mass destruction (PMD) will be sanctioned first, and later sued by the Air Force.
If other countries think we kick ass now, wait until they meet our legions of lawyers.

By patenting the firewall the Navy may stop those companies that seem to patent things solely to send you extortion notes for licensing. Typically the federal gov't can't/doesn't license them. Since they are taxpayer funded they seem to be "Ours." Actually there are a lot of patents that I wish they had. Anyone know for sure if this will essentially place the firewall patent in the public domain?
From what I've read of the actual patent so far, it appears that it is a very specific implementation of a specific type of firewall.
See claim 3 for example - What they are describing implies a machine with two dedicated processors with shared memory, one for each network. Note that for what they are describing, a typical SMP or dual core system does NOT count - It seems that they are effectively describing two seperate machines in one box that can communicate via shared memory.
Also other claims imply that the patented system will be talking to each network at the application level, so it's more of a special form of proxy server rather than a firewall.
I don't have time right now to read further details, but keep in mind that even specific patents can appear much broader than they are in the abstract. For example, one can't patent the wheel or a tire, but when patenting a tire with a specific tread pattern, it might appear in the abstract that the applicant is trying to patent the tire in general even when they're not.

i love it. "the navy patents the firewall!!!one!". and they include a link to a Patent Application.
here's a tip: an application aint a patent.

Is this the MPAA? Is this the RIAA? Is this the DMCA? I thought it was the USA!
To all of you shooting from the hip: STOP! You're just making a fool of yourself.
Read the claims. Read them in light of the description of the patent. And learn patent terminology. Then you can make some general statements. And if it's only a publication (like this navy one), not a patent, don't even bother with that.
If you must draw a conclusion, and you're sure this is about a firewall, then at least go the step to know they are claiming a type of firewall. Which is perfectly legit (as long as it contains a new, non-obvious element). If you think otherwise, go learn about patents, come back, and then we'll talk.
PS:plurality is a very common patent term. It means more than one (duh!). Not even worth making a comment about, but someone felt compelled to jabber about it.
The world is made by those who show up for the job.

I can only several reasons that the government patenting something might be fair:
1) If a non-American entity (person, company, etc.) wants to use the technology, then it would basically be the American people selling the right to use the patented technology to non-Americans. In that way, Americans, who funded the research, win.
2) In some sense, something that benefits the Navy does benefit Americans in general. When the Navy licenses a patented technology to a private company, this (hopefully) causes some money to move from that private entity to a public one (the U.S. govt.) That basically co-funds something that all taxpayers were having to chip in on the payment of (that is, the cost of government / national defense).
3) Suppose that even if a technology has been made available for free, no one can afford to commercialize it if more than one company will be doing the commercialization. This might happen, for example, if the market is very small. For example, if there are just two competitors and 10 companies that might build the device, then each of those 10 companies facies great risk. So granting an exclusive license to use the patented technology could be the only way to get even one company to build the device in that situation.
The government has patented numerous things.
The link below is just one of those things.

The patent does not apply to packet filter firewalls (the majority of all firewalls, including the ones you listed) because it says the packets traverse the application layer. The market for application layer (proxy) firewalls is actually pretty narrow. The main contender (SideWinder) recently bought out the 2 main competitors (Gauntlet and CyberGuard). Whether it would apply to hybrid firewalls (packet filters that do deep inspection, like Checkpoint and Netscreen) is less clear.
Software sucks. Open Source sucks less.
As a project lead for the Army at an installation that does a lot of R&D, when we patent something 1 of 3 things happen to it. 1) We grant rights to the patent to someone in industry to produce the produce on a large scale for us. 2) (more common) We just transfer the patent to the company that will produce the product for the military. Personally I think #1 is a better option, but #2 happens a lot. 3) The patent becomes public domain, and the military never has to worry about being sued over licensing issues from someone else developing the technology.
Read claim 3: "The method of claim 2, wherein the configuring includes implementing the network interface system with distinct sets of first and second processors, the first and second processors having a shared memory." ...configuring the interprocessor communication channel to communicate moving averages ...and configuring the network interface system to prevent the shared memory from overflowing ...by controlling the ... network interface system. "
This puts the firewall smack into the hardware, not on the extension cord going out of the building. This is a firewall between computers that are in the same cabinet, not on the same internet. It also provides for loadleveling in Claim 6:
"...via an interprocessor communication channel;
Further claims in the patent app show that the data is not transferred by just any program, but by an API on the firewall CPU and the boxen on either side of the firewall. This looks like some seriously secure stuff here.
Also, your normal firewall allows inside ("your" computer) to talk outside (the internet) freely, but prevents outside from getting in. This patent app specifies that the outside can talk freely to the inside, but the inside can't just blab to the world. This keeps the worms in the can. It also randomizes time signatures so that form of black box analysis won't tell you anything.

Then why not allow government departments that invest their time and effort to have the privilege of patents and subsequent liscenses as well?
Patents exist to promote novel and usefull inventions. The method behind this is granting exclusive rights for a limited amount of time to the inventor so (s)he can compensate for investment and make a buck from the invention.
The granting of exclusive rights is how society 'pays' the inventor for his efford and investment.
In the case of a government department however society already payed the inventor for both. The investment comes from tax money, and so does the salary of the inventor.
There is no reason for society to pay twice for the same thing.
Do you beleive that all companies should just be able to take a government department's work in a particular field and use it without having to pay for it?
As long as they pay taxes they already payed for it.
Now that's what I call a Submarine Patent!
