Patents

Me around the Web

by on September 30, 2008 · 4 comments

Three new pieces by me are up this week:

  • Over at Ars Technica, I’ve got the first installment of a three-part series on the future of self-driving cars. The technology has made tremendous strides in the last five years, and we’re now at the point where it’s less a science fiction concept and more an engineering challenge. Cars that can navigate simplified urban roads already exist in university research labs, and cars on the market today have simple forms of self-driving, including adaptive cruise control and automatic parking. Driven by safety concerns, these technologies will only get more sophisticated until (perhaps sometime in the 2030s) they converge with the academic research and make possible the first fully autonomous vehicle. In the next two installments, I’ll talk about the social implications of this shift and the new policy issues that are likely to arise as a result.
  • My inaugural post at Freedom to Tinker is up. Cato recently unveiled the latest edition of its Supreme Court Review, which included an article by F. Scott Kieff about the Quanta v. LG decision. Kieff argues that the high court’s unanimous decision on the patent exhaustion doctrine undermined the freedom of contract. I offer a different perspective on the decision. I’ll be posting at FTT regularly (including a follow-up post on Quanta this week) so I encourage you to subscribe, if you don’t already.
  • There’s an “ask the experts” feature at Cato on Campus, Cato’s website for college students. A student emailed in asking about the libertarian position on “intellectual property,” so explained the basic divisions among libertarians (which are largely the same divisions among non-libertarians) on the issue, and then gave three examples of changes I’d like to see to patent and copyright law.

  • If you find the title of this post provocative, you’ll be interested in a Cato Institute book forum on Friday, October 10th.

    In The Crime of Reason, Nobel laureate in physics Robert Laughlin argues that intellectual property laws and government security demands threaten the development of new knowledge. Without change, we risk bequeathing our heirs a world where knowledge is criminalized and our intellectual tradition of unfettered inquiry is lost.

    The event should be a fascinating inquiry into the role of information and information rules in our society. Thomas Syndor of the Progress & Freedom Foundation will comment. I’ll be your humble moderator. It’s noon on Friday, October 10th, at the Cato Institute, 1000 Massachusetts Avenue, NW, Washington, D.C. Luncheon to follow.

    Taxpayer Patent Extortion

    Wow. Mike Masnick writes about NASA’s plan to auction off some of its patent portfolio to the private sector. When I read this I had to do a double-take: NASA has a patent portfolio?

    This is absurd. The purpose of patent law is to promote the progress of the useful arts by giving inventors an incentive to invent. NASA engineers already have an incentive to invent: they’re being paid taxpayer dollars to do so. Accordingly granting patents to NASA is a pure dead-weight loss to the economy. It restricts the free flow of ideas with no offsetting benefit from improved incentives. Indeed, this is precisely why the copyrights on government-created works are immediately placed in the public domain.

    Why isn’t there a similar doctrine in place for patent law? I can’t see any reason government agencies should be allowed to apply for patents in the first place, but if they are going to do so, they should be placed in the public domain the same way copyrights are. How can it be legal for a government agency to use taxpayer money to perform research and then obtain patents that effectively prohibit most taxpayers from using the results of that research? If I helped pay for research, I should be free to use the results.

    My recent comments on a developers experiment in combatting software piracy, posted here.

    And an absolutely brilliant adventure in free speech marital event planning, here (OT).

    [This post will be geekier than average. Apologies in advance to non-programmers]

    One of the interesting aspects of Intellectual Property and Open Source is the frequent use of programming metaphors to explain legal concepts. Given the audience, it’s a clever approach. Most of the analogies work well. A few fall flat.

    I found one analogy particularly illuminating, albeit not in quite the way Lindberg intended. He analogizes the patent system to memoization, the programming technique in which a program stores the results of past computations in a table to avoid having to re-compute them. If computing a value is expensive, but recalling it from a table is cheap, memoization can dramatically speed up computation. Lindberg then compares this to the patent system:

    The patent system as a whole can be compared to applying memoization to the process of invention. Creating a new invention is like calling an expensive function. Just as it is inefficient to recompute the Fibonacci numbers for each function invocation, it is inefficient to force everyone facing a technical problem to independently invent the solution to that problem. The patent system acts like a problem cache, storing the solutions to specific problems for later recall. The next time someone has the same problem, the saved solution (as captured by the patent document) can be used.

    Just as with memoization, there is a cost associated with the patent process, specifically, the 20-year term of exclusive rights associated with the patent. Nevertheless, the essence of the utilitarian bargain is that granting temporary exclusive rights to inventions is ultimately less expensive than forcing people to independently recreate the same invention.

    The caveat at the beginning of the second paragraph is huge. In the software industry, at least, any patent filed in the 1980s is virtually worthless today. But even setting that point aside, Lindberg’s analogy provides a helpful analogy to explain why patents are a bad fit for the software industry: it’s like implementing memoization using a lookup table without a hash function.

    I’m reviewing Van Lindberg’s Intellectual Property and Open Source for Ars Technica. The first chapter is an introduction to the theoretical concepts that Lindberg describes as the “foundations of intellectual property law”—public goods, free-riding, market failure, and so forth. I’ve found several of the assertions in this chapter frustrating.

    For example, on p. 8, Lindberg writes:

    We want more knowledge (or more generally, more information) in society. As discussed above, however, normal market mechanisms do not provide incentives for individuals to create and share new knowledge

    Italics mine. Now, this claim is simply untrue. Normal market mechanisms do, in fact, create incentives for individuals to create and share new knowledge. Mike Masnick has offered one excellent explanation of how they do so. See also Chris Sprigman and Jacob Loshin and the restaurant industry. Plainly, lots of new knowledge is created without the benefit of copyright, patent, or trade secret protection.

    It’s likely that Lindberg is just being sloppy here, that he meant that markets do not provide sufficient incentives for creativity. This is a perfectly plausible view—indeed, it’s the mainstream view among scholars of patent and copyright policy. But even this weaker formulation is controversial. Boldrin and Levine, for example, are two respected economists who deny it. Even this weaker formulation, therefore, is too strong. Certainly many scholars (myself included) believe markets produce insufficient creative expression, but the point has certainly not been proven conclusively.

    I was pleased to see Braden’s excellent new paper on the use of self-serving lobbying tactics to limit competition and promote particular business models at the expense of others. As Braden and his co-author point out, some of the most important competition in the software industry has become less about products than about business models. Some software companies sell the software directly, while others give software away as a means of selling hardware, services, or advertising. And in many cases, public policy debates in the software industry are thinly-veiled attempts to give some business models unfair advantages over others.

    Braden produced a chart that gives some helpful examples of policies that tilt the economic playing field toward one business model at the expense of the others:

    As you can see, software patents promote proprietary software business models at the expense of business models based on giving software away for free (and, it should be said, at the expense of people who want to give software away for free on a non-commercial basis). Similarly, the DMCA promotes proprietary software business models. They neglected to put it on the chart, but the flip-side is obviously true: the DMCA harms free software, commercial and otherwise, by making unauthorized interoperability with DRMed software a crime.

    Paper or Plastic?

    Hit and Run has the story of a patent that should never have been granted.

    I’ve got two new articles on patent reform out today, and by sheer coincidence, both of them are related to the work of law professor John Duffy. First, over at Ars Technica, I analyze John Duffy’s article at Patently-O, where he argued that the US Patent Office has shown a growing hostility toward software patents over the last couple of years. He seems to be right that the Patent Office is becoming more skeptical about software patents, but of course we have a difference of opinion about whether this is a good thing:

    Duffy seems to regard the end of software patents as a calamity for innovative companies, but his argument is awfully thin. Duffy focuses on Google’s PageRank patent, which he has long regarded as a poster child for software patenting. He describes it as “surely one of the most famous and valuable of all modern software patents,” and suggests that the invalidation of Google’s patents would be a calamity for the company. Curiously, however, he never explains how Google benefits from this or other patents in its portfolio.

    Google derives little, if any, of its revenue from patent royalties and has managed to dominate the search engine marketplace without suing its major rivals for patent infringement. Indeed, it appears that the primary function of Google’s patent portfolio is as a defensive stockpile to be used if any competitors should sue it for patent infringement. If that’s true, then the only real effect of software patent abolition on Google would be that the company could lay off its patent lawyers.

    Patent Failure Review

    by on July 16, 2008 · 1 comment

    Over at Ars Technica, I review Bessen and Meurer’s Patent Failure. It’s a fantastic book that has had a big effect on my recent thinking about patent issues. Check it out.
