LSI Patents the Doubly-Linked List

An anonymous reader writes "Back in April, LSI was granted patent number 7028023. This is a patent on a stunning new technique in data structures ... the concept that a linked list can in fact have multiple orderings. Of course, this has been used since the beginning of (computer) time in the form of doubly-linked lists. Even if LSI wants to (somehow) claim that the doubly-linked list doesn't count as prior art, maintaining linked lists of graphical objects sorted by both x and y co-ordinates for collision detection has been done since "graphical objects" meant ASCII characters on a green-on-black screen, and has probably been widespread in databases for probably even longer."

OK, this is just ridiculous.

[Josh Lindenmuth]

While one could at least make a somewhat intelligent argument why software that costed companies like Apple or Microsoft Millions (or even Billions) of dollars to create should be patented, there's no logical argument for patenting data structures. This patent was first submitted in 2002, which probably means it was turned down and appealed at least twice. As anyone who has gone through the patent process knows, if you appeal enough times eventually you might find an examiner who is clueless enough to grant the patent.

I couldn't imagine LSI ever intends to protect the patent (since it obviously would never stand up in court). Most likely, they are just seeking bragging rights "Hey look, we had 30 patents approved this year".

Our government needs to more clearly delineate what software can and cannot be patented in order to prevent more ridiculous patents. I'm more in the 'No Software Patents' camp, but I think there are exceptions, particularly for very specialized software in specific industries.

      No! That would only make things worse. Government is always too slow in this kind of thing anyway. Just do away with "software" patents completely. Copyright yes - of the FINISHED WORK. Patents no. It's like a painter who wants to patent or copyright every separate blob of paint on his canvas. This does not make sense.

An outright "No Software Patents" stance would say that any company could then duplicate the oil company's unique software, leaving them no protection for their massive investment and intellectual property.

      You know, it's up to the oil company to make sure that no one gets their hands on the software, just like Coca Cola makes sure no one finds out about the "secret formula". If someone outright steals the software and sells it to someone else, copyright law is now full of 6 figure fines and jail time - enforce THAT. What's really happening is that people are not protecting systems. They are trying to "protect" tiny parts of programs. This essentially stops anyone else from creating a program that does roughly the same thing. Even if it does that same thing in a different way, it will definitely wind up in court. That's absurd. Yes the whole system you describe warrants protection.

      But not the individual algorithms for goodness sakes. Here you could argue "but what about scientific formula and drugs, and the pharmaceutical industry". That's different - these people are FORCED to reveal their work in order to pass the FDA. They need greater protection since they can't keep the contents of their meds a secret. But for the rest, I think most of burden of protecting trade secrets should fall on the industry that has the secret - not everyone else having to prove via defensive litigation that their software does NOT infringe on a "patent" for some algorithm or other because it does something similar.

The investment and results are the same in either case, the only difference is that we're talking about something physical instead of software.

The "only" difference? You make that sound like it is of minor importance. It is not. Software is intellectual property. You don't go around patenting the plot of a book or a movie, the chord-progression in a song, the concept of "self-help" audiotapes, or the new mathematical theorems discovered by some genius mathematician (or algorithms, business methods, or sequences of base-pairs for that matter, although sadly the US has started doing just that)

Patents are a very specific right that is granted specifically to give the inventor of new inventions a fair chance of recouping his investments. Unlike music or software, which is protected by copyright, once someone invents e.g. the four-stroke combustion engine, anyone is free to produce it. Patents are designed to help the inventor here, it's not a general purpose mechanism of protecting all kinds of "ideas". The "default" position is to have no patents at all. Arguing that since patents protect one kind of idea, it should protect other kinds of ideas, is completely silly. And patenting software, business processes, or genes is also silly.

If we remove all software patents, we also remove part of the incentive for large corporations to invest in software. There needs to be some protections, they just need to be smart

Exactly. We remove some of the incentive for large corporations to invest in software. At the same time, most of the incentives remains, such as having some new software "that takes existing geological maps and analyzes it in a novel way". This software can be used internally for finding oil, it can be licensed to other companies, or used in lots of other ways to generate profit.

Also, it should be made clear that even if software patents benefits large companies (which I believe was true at some point, although I'm starting to doubt it still is), it does not benefit small companies. Taking away software patents makes it easier for small companies to invest in software. I'm not particularly in favour of laws that only benefits large companies.

You know, it's up to the oil company to make sure that no one gets their hands on the software, just like Coca Cola makes sure no one finds out about the "secret formula".

And thus, the company never publishes the things they discovered and society has to keep reinventing them, since everyone who discovers them keeps them secret. Whereas with patents, the company gets a monopoly on that particular thing for 20 years and then society is free to use it for eternity. What you propose just results is massive duplication of research.

Re:OK, this is just ridiculous.

[Anonymous Coward]

Patents, therefore, are a tradeoff. They protect the inventor while encouraging them to disclose their techniques. Thus, the inventor gets something (a government protected monopoly for a limited period), and society gets something (access to the details of the technology).

The problem is that for almost all software patents, a monopoly is being granted for details we did not actually need to know, because they are obvious to anyone 'skilled in the art'. Or even 'unskilled in the finger daubing'. The value of the monopoly is much, much, greater than the value of the information we're getting.

I'd venture that this is true not just of software patents, but in software, the progress made in the absence of a patent regime for so many years spoke volumes about the lack of a need for patent protection.

Re:OK, this is just ridiculous.

[FireFury03]

What you propose just results is massive duplication of research.

So basically we have 2 options:
1. Disallow software patents, people wishing to protect their work will keep it secret and other people can come up with their own (probably very similar) solutions to the same problem.
2. Allow software patents and therefore prevent *anyone* else from producing anything similar on their own.

Option (1) seems like the better option to me since at least it allows third parties to come up with a solution. Remember that in most cases the patent holder either won't licence their technology at all, will licence it for infeasable amounts of money, or put very restrictive terms on the licence (what good is the ability to use some technology if you're not allowed to integrate it into your FOSS project?)

And this is assuming you even realise you're infringing someone's patent. Remember, you're still infringing a patent even if you came up with the idea on your own - all too often a product is developed independently, becomes very successful and then the producer is sued for infringing a patent that they had never heard of. It's now got to the point where it's pretty much impossible to write a piece of software without infringing _someone's_ patent.

Also, from my experience the threat of people suing for patent infringement often motivates corporations to keep source code closed which they would otherwise be happy to open to the public - this is certainly not a good thing.

Patents have been turned into ammunition for large corporations - having 100,000 patents prevents the guy who only has 80,000 patents from suing you. Unfortunately the little guy who's got no patents and no money for lawyers gets completely squashed in the process. Maybe patents are sometimes good for small inventors, but they are open to abuse by large organisations. And even if you are in the right and have prior art, how the hell are you, as a single person on your own, going to be able to defend yourself in court against some huge corporation such as IBM, Microsoft, HP, etc?

Give this AC the whole EFFing bakery. Finally, someone who actually understands the effects of software patents in the real world.

In the "copyright debate" there is lots of arguing back and forth about the necessity of copyrights to encourage the "progress of science the useful arts." But it is all just a bunch of postulating.

Here we have demonstrable proof that software patents are not necessary because the whole shebang is only about a decade old, and their creation has not done anything to markedly improve the situation. If anything, it has been the reverse with proprietary software stagnating and consolidating into a handful of big corps like MS and Oracle. All the really innovative stuff is happening in the Free world which is antithetical to the idea of software patents.

It's probably worth it if you're a CEO for a corporation. After all, CEOs don't spend their own money, they spend the company's money. It would hurt the shareholders, but if it makes the shareholders think that the CEO is doing something awesome (what could be more awesome than synergizing an IP portfolio?) that will make money, then they'll keep paying the CEO.

Bragging rights are totally worthwhile, if they keep investors happy. And corporations routinely spend up to 30% of their revenue on keeping investors happy. The cost of a few bogus patents are peanuts as a part of that.

Re:OK, this is just ridiculous.

[Knuckles]

I can't see any way of creating a definition that would have a chance in hell of ever being anything but ambiguous and self-contradictory.

That's because being ambiguous and self-contradictory is its purpose.

How to obtain a U.S.-patent:

[foobsr]

1. Take a fundamental concept
2. Describe it as complicated as possible
3. Put the result through a patent-lawyers office in order to make sure the claims get even more obfuscated
4. Apply successfully for a patent
5. Profit!

Patent reform anyone?

[sinij]

Patents do not have to be meaningful, or even have a remote chance of standing up in court. They are weapons in corporate world and you use them mostly to cause damage. If your public company is sued you lose money in legal fees, might lose investor confidence in a critical moment and overall end up in a loss even if you easily won it. Just look at Research In Motion if you need to see how much damage can frivolous patent deal.
