morality != legality (Score:1)
There are cases where a law is passed that does not help(and sometimes hurts) the public.
Bad laws have been passed for:
purposeful racial discrimination
purposeful religious intolerance
Corporate greed to protect/extend exclusive rights to information.
You have two for such laws:
1) Beg the government to change the law. To do this, you will often need more money and power than whoever backed the law.
2) Ignore the law, knowing that:
It is unenforcible.
and/or
If taken to a higher court, the law will be struck down.(Assuming that judges are less bribed than congress)
For the specific issue at hand, 2 applies.
As we have seen with mp3 and as we will see with CSS, It is very dificult to enforce a software patent when open source implementations exist, as there is really no-one to sue, except the whole internet, which is not feasible(As CCA will see).

1. Computer science/coding is ill suited for patenting, because many "best practices", common practices, and obvious things simply aren't documented. The culture of programming is very much an oral tradition, learned by watching others and asking questions of them.
2. In the U.S., patent examiners have an incentive to not challenge patent applications - the applicant can haul them into court to explain why they denied the patent, but they don't have to explain why they approved it. Not to mention most examiners aren't involved/knowledgeable enough about computer science in the first place.
3. Patents these days are being used as another form of cash that is being traded around by companies - ie, Motorola and AMD cross-licencing patents, various companies trading patents for other incentives, etc. If you don't have patents, you don't have anything to trade for/with (okay, not a software example, but the principle still holds).
4. Challenging existing patents in court can get expensive, not something the average Joe can do. Some companies can get away with threatening to enforce patents, simply because whoever is "violating" the patent can't afford to fight it.
And there are countless examples of bad software patents, too numerous to mention, that effectively stifle innovation, contrary to the original intent of patents.
If you all remember the /. interview with the patent attorneys, you'll remember that it's actually advisable not to look up patents: if you get taken to court over a patent violation, you'll get a lesser penalty if you didn't know you were violating a patent than if you did know. Which creates sort of a catch-22 - develop a product, if it's violating a patent, you'll never know unless you get sued, at which point all your efforts have been wasted.
Much of this has been stated previously by RMS and/or ESR and various other people. A good resource for this is the FSF [fsf.org].

Great idea at first, but today IP law has problems:

Going alittle further into this, and at the risk of losing sight of the original topic, I would also point out that IP violations seem to have far worse fines than even raping somebody - is this reasonable? Should we not clamor for reasonable punishment for violations of the law? This is another problem I have with so-called "intellectual property" rights - since when was your computer somebody else's property? What right do they have to break into your home, and take your computer? Why can't they simply remove the offending content (or backup your harddrive and return your data immediately)?

Using your statement above, its patentability is undecidable. Therefore, your statement is incomplete. Go read Roger Penrose.
Not all of math is obvious. One of the clear elements of patentability is non-obviousness. For example, look at Andrew Weil's use of the Taniyama Conjecture about elliptic curves to solve Fermat's Last Theorem. *That* was certainly not obvious. I believe that, if he had wanted to, he could have written a program based on his work and gotten a patent on it.
I agree with you that patent examiners in general don't know enough about software to make adequately well-informed decisions about the patentability of software, but that's a meatware failure, not an indictment of the entire system of software patents. If they *did* know enough about software, most software patents would *not* be granted and we wouldn't be having this discussion.

Nobody should be able to "own" information about the quickest way to sort, or the makeup and function of a human gene. If we completely rid ourselves of patents, would our way of life collapse? No. People would still want to pay money for good and services that they cannot produce for themselves or don't have time to do for themselves. Companies would still compete for those consumer's dollars. The companies that offered the most desireable implementations at a good price will flourish. The current anticompetitive situation in which potential comptetitors, who might offer consumers a cheaper or higher quality implementation, are held at bay by threats of patent litigation does not help consumers (who are the "society at large"). I think people need to get past the idea that an idea entitles you to some sort of windfall just because you got to the patent office first. That just invites laziness. Consumers don't give a flip about your idea. They want a product, and they want to buy the cheapest, best quality version of it they can get. That process of creating, distributing, and supporting a product is 1% inspiration and 99% perspiration. The rewards should go to the people that best give consumers what they want, not those who are best at hoarding "intellectual property". So if there is no IP, does that mean that nobody is going to do any more research? No! You will still do research to get ahead. Even if others can duplicate your work over time, you still get the rewards of faster time to market. That's right - you should be rewarded for being first to market, not first to the patent office! And when others are hot on your heels, you'd better think of the next step in getting ahead. Or some competitor will, and you will fall behind. That's too bad for you. But it's good for everyone else (consumers/ordinary people). It just makes a lot more economic sense.

Both are essentially science-based but with a heavy artistic component, both benefit from similar development cycles. And both are legitimate patents.
The point being that algorithms in their purest form can be reduced to mathematical descriptions. If you have ever read Dijkstra (IMHO every CS student should be _required_ to read Dijkstra) you should also know that imperative programs can also be mathematically constructed so that they are correct by construction.
Functional languages are used in serious development, the kind that mainstream imperative and OO programming just can't handle. How about Erlang ? Ericsson uses it in phone switches, hardly a trivial academic task. Functional and other exotic languages are everywhere but you just haven't noticed. There may be job offers for people with Java/C++/Perl/OO/UML/CORBA/WAP/XML/Unix/NT in the papers but that is no indication that functional languages aren't used. People that know special languages get more demanding and interesting jobs through different channels than newspaper ads.
As for patents. The problem, IMO, is the duration and that they can also be used (in the US) to stop non-commercial use as well. The new proposed European utility model would still allow hobbyist use (research/non-commercial), even though it would also allow software patents (though not called patents) for a maximum of 10 years. Previously software patents weren't allowed. The way the U.S. is lobbying for software patents makes me sick. The WTO trade agreement includes parts about intellectual property which is clearly out of line with current European legislation. I'm confident that our leaders will ignorantly accept the goals of the WTO to be good and accept the new patent legislation as a part of the WTO agreement. This kind of bundling is insidious. I wish people would stop consuming mind-numbing entertainment and think for a change. Leaders can not make informed decicions unless people inform them on the possible effects of their decisions.

A tool is something tangible, something by it's very existance limited. A patent on a tool requires that you be able to offer a model to the PTO, or at least really detailed designs. In order to violate a tool patent, you have to have developed a tool that operates in substantially the same way. A tool has physical form, requiring financial investment and presumably created with the hope of reaping financial rewards; patent law is seldom enforced on non-commercial tools since they are few and by their very nature limited. A patent on a tool merely restricts other tools.
Technology is something completely intangible, an idea. No effort need be made to implement the technology to get the patent. To violate a technology patent, you need merely to have the same idea. Technology is often explored for the joy of it, with no commercial or financial involvement; patent law does get enforced against non-commercial technology, because the ideas can spread without limit. Regardless, the bottom line is that while patents on tools restrict tools, patents on technology restrict thoughts.
Restricting thought is a very dangerous thing. In particular, patenting thought is forcing technological creativity in this country to be mired in tons of legal bullshit from laws being misapplied somewhere they were never intended to go. The USPTO needs to stop patenting discoveries and focus on patenting inventions like they're supposed to.

Patents don't really stifle innovation, they stifle imitation. Patents are public documents, anybody can look at them. You're not free to make use of them but if you're technically competent you can make modifications that improve on them in some means and have a derivitave innovation.
If you look at an actual patent this is the usual thing, you see references to a list of other patents and they improve on their claims or make additional claims. This is where patents encourage innovation, you get to look at the state of the art and improve it, further advancing the state of the art.
Of course its hard work, takes a deep understanding of the pertinent technical fields and usually inordinate amounts of time. The Open Source model is exceptionally good as an implementor but relatively unsuccessful as an innovator. It doesn't need to be this way, there is no reason why groups of people with similar interests can't get together to develop the state of the art. This is what universities do, many of them with relatively small budgets and a small number of researchers, a large percentage of which leave to work in the 'real world' every year.

No, I actually do know about functional languages. I'm a CS undergraduate and there's a compulsary module on Miranda I had to take. Didn't much like it and haven't touched it since, but I'm aware of its existence.
One sentence in particular screamed out at me, though:
To which I'd have to reply - sorry if this sounds like namecalling - that you're more than a little ignorant if you think all that many software developers use functional languages. Sure, they're a nice curiosity and sure, they're useful for some stuff - I've done that short quicksort and mergesort, too - but how much genuine, commercial use is there? Almost none.
Next time you see a computing paper of any description, find the recruitment section. And look which languages are in demand. I see plenty of C/C++, Java, VB (spit)
The point here is relatively simple: while functional languages may well be rather closer to mathematics, they just aren't used in any quantity for serious development. And they're still not pure maths.
Computer programming the way almost all do it - imperative programming - is most definitely not mathematics and the parallel with engineering is a good one. Both are essentially science-based but with a heavy artistic component, both benefit from similar development cycles. And both are legitimate patents.

The actual definition of a patent (from the patent office) is "Any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof." So, while you say that the Patent Office needs to stop patenting discoveries, and focus on inventions, I think you are missing the point. There's no reason why a "discovery" cannot be one of the listed (patentable) objects. Most software patents relate exclusively to a "process".
I am greatly disturbed by the number of people who seem to think that all patents do is stifle innovation. This is absurd. Patents stifle copying, and nothing more. If one is truly going to *innovate* then they won't be in violation of a patent law, will they? Remember the line "improvement thereof" -- inventors are encouraged to build a better mouse-trap. It can even work on the same principals as the original mouse-trap, so long as it improves on the model in some non-obvious way. That's why patents (once they are fully filed) are PUBLIC.

I think you'll find that you are, in fact, mistaken about that last part. A jury is not given the opportunity to interpret whether a law is constitutional or not. This is the Supreme Courts decision.

The distinction is that a jury (in theory, if not wholey in practive) cannot allow their emotions, as to how they feel about the "justice" of the law, get in the way of their decisions on whether or not someone is guilty of breaking it.
Having said that, I will agree that certain laws *do* need to be broken. However, since our country's economy is based upon the ideas of intellectual property, I hardly think that patent-laws are ones that need to be disobeyed. For moral and legal reasons.

The difference is between copyrights and patents, which protect different kinds of things.
Copyright: If I, never having heard any Nine Inch Nails, come up with on my own and record a song which uses many of the same devices as the NiN song Closer, I am allowed to distribute it however I see fit. (proof may be a problem, though)
Patents: If I use the same (or sufficiently similar) process (now patents seem to be applied to simply 'ideas') as a patent holder, this is illegal, even if I researched it myself.
Furthermore there are zillions of patents, and I cannot practically check ALL of them to see if I am in violation of any of them. Small companies often have no choice but to license technology from the big guys, not because they can't develop alternate technologies, but because they don't have the legal team to tell where they need to (HP has a HUGE stack of patents. Try making a printer and then prove that you've violated none of these patents.)
Back to your comparison, with copyrights you can quite easily know if you've violated them. Did you create X yourself? Well, then you should be okay. (Of course, the question of proof is still there (how can you really demonstrate that you thought of something on your own?) but at least YOU can know whether you're behaving legally).

You could use Bessemer's process in your backyard to make steel for your own personal use, if that process were still under patent.
Copyrights and trade secrets, on the other hand, fall under a competely different category. Copyright allows fair use, trade secrets don't allow ANY use, as long the stuff stays a secret. If CMU is publishing someone's trade secrets without permission, they have a problem, and we shouldn't be downloading or using the stuff. Otherwise, I think that it's probably ok for us to look and learn.
Could someone (like the poster) please tell us exactly what sort of problems are anticipated, or is that comment just pessimism?

This may have something to do with the credo many geeks subscribe to: That information should be free. Patents were originally invented to support truly innovative work where the author invested considerable time and energy into it. It was intended to make technology publically available so others could view and make improvements on the original idea. The tradeoff for a patent is that the public gets to view the work - and it is protected against other commercial enterprises using the patented invention for a period of n years, allowing the developer to recouperate the cost.
This was the original intention, however in recent years the purpose of patents has been mutated and mulilated: they are now often used offensively in court battles to keep competing products from entering the marketplace, they are filed in the thousands each month, many for trival innovations - witness Amazon's "one-click" patent. Such things are obvious and trivial. The USPO should have rejected it out of hand, but due to a lack of expertise in the computing arena they are patenting everything and it is having massive legal repercussions. The net result is that companies with large amounts of resources can afford drawn-out legal battles or do massive cross-patenting to keep their legal butts covered. Individuals, however, cannot do this. We have no money, and thus are of no interest to the patent holder(s).
This is why many people on slashdot are openly hostile towards patents and intellectual property - it is a matter of moral belief and civil disobedience that people copy the DeCSS code, or this code, and freely redistribute it. Many of us would have a higher respect if the system worked as designed and afforded individuals the same rights as corporations.

I've posted a question on SourceForge about what sort of data comes with this system, but without either data or the ability to re-train the system, the usefulness of the recognizer will be curtailed.

Mathematics and facts of the natural sciences are specifically noted as unpatentable in patent law.

Patents would only interfere with this and slow progress.
Computer science is not only a branch of mathematics (algorithms are as old as the abacus, and were formalized long before the first programmable computer), but shows all the same behavior that makes it an unsuitable field for patents. People proudly explain their clever algorithms and data structures for no direct monetary gain. Allowing software patents has only interfered with the progress of the field.
Practically every software developer breaks software patent laws. There are a great many software patents on simple, obvious, and common practices, and it is generally not feasible even to check whether you are infringing on anyone else's patents. It is also not economically feasible to legally challenge every bogus patent that one wishes to use. If one were to attempt to remain in full compliance at all times with patent law, it would be hundreds or thousands of times more expensive than the actual software development.
