Software Patents and Literary Patents {#software-patents-and-literary-patents .chapter} +======================================== + +@firstcopyingnotice{{ Copyright © 2005, 2007, 2008 Richard Stallman\ + {This essay was originally published on <http://guardian.co.uk>, on +23 June 2005. It was then titled “Patent Absurdity” and focused on the +proposed European software patent directive. This version is part of +@fsfsthreecite} When politicians consider the question of software +patents, they are usually voting blind; not being programmers, they +don’t understand what software patents really do. They often think +patents are similar to copyright law (“except for some details”)—which +is not the case. For instance, when I publicly asked Patrick Devedjian, +then Minister for Industry in France, how France would vote on the issue +of software patents, Devedjian responded with an impassioned defense of +copyright law, praising Victor Hugo for his role in the adoption of +copyright. (The misleading term “intellectual property” promotes this +confusion—one of the reasons it should never be used.) + +Those who imagine effects like those of copyright law cannot grasp the +disastrous effects of software patents. We can use Victor Hugo as an +example to illustrate the difference. + +A novel and a modern complex program have certain points in common: each +one is large, and implements many ideas in combination. So let’s follow +the analogy, and suppose that patent law had been applied to novels in +the 1800s; suppose that states such as France had permitted the +patenting of literary ideas. How would this have affected Victor Hugo’s +writing? How would the effects of literary patents compare with the +effects of literary copyright? + +Consider Victor Hugo’s novel Les Misérables. Since he wrote it, the +copyright belonged only to him. He did not have to fear that some +stranger could sue him for copyright infringement and win. That was +impossible, because copyright covers only the details of a work of +authorship, not the ideas embodied in them, and it only restricts +copying. Hugo had not copied Les Misérables, so he was not in danger +from copyright. + +Patents work differently. Patents cover ideas; each patent is a monopoly +on practicing some idea, which is described in the patent itself. Here’s +one example of a hypothetical literary patent: + +- Claim 1: a communication process that represents in the mind of a + reader the concept of a character who has been in jail for a long + time and becomes bitter towards society and humankind. +- Claim 2: a communication process according to claim 1, wherein said + character subsequently finds moral redemption through the kindness + of another. +- Claim 3: a communication process according to claims 1 and 2, + wherein said character changes his name during the story. + +If such a patent had existed in 1862 when Les Misérables was published, +the novel would have conflicted with all three claims, since all these +things happened to Jean Valjean in the novel. Victor Hugo could have +been sued, and if sued, he would have lost. The novel could have been +prohibited—in effect, censored—by the patent holder. + +Now consider this hypothetical literary patent: + +- Claim 1: a communication process that represents in the mind of a + reader the concept of a character who has been in jail for a long + time and subsequently changes his name. + +Les Misérables would have been prohibited by that patent too, because +this description too fits the life story of Jean Valjean. And here’s +another hypothetical patent: + +- Claim 1: a communication process that represents in the mind of a + reader the concept of a character who finds moral redemption and + then changes his name. + +Jean Valjean would have been forbidden by this patent too. + +All three patents would cover, and prohibit, the life story of this one +character. They overlap, but they do not precisely duplicate each other, +so they could all be valid simultaneously; all three patent holders +could have sued Victor Hugo. Any one of them could have prohibited +publication of Les Misérables. + +This patent also could have been violated: + +- Claim 1: a communication process that presents a character whose + given name matches the last syllable of his family name. + +through the name “Jean Valjean,” but at least this patent would have +been easy to avoid. + +You might think that these ideas are so simple that no patent office +would have issued them. We programmers are often amazed by the +simplicity of the ideas that real software patents cover—for instance, +the European Patent Office has issued a patent on the progress bar, and +a patent on accepting payment via credit cards. These patents would be +laughable if they were not so dangerous. + +Other aspects of Les Misérables could also have run afoul of patents. +For instance, there could have been a patent on a fictionalized +portrayal of the Battle of Waterloo, or a patent on using Parisian slang +in fiction. Two more lawsuits. In fact, there is no limit to the number +of different patents that might have been applicable for suing the +author of a work such as Les Misérables. All the patent holders would +say they deserved a reward for the literary progress that their patented +ideas represent, but these obstacles would not promote progress in +literature, they would only obstruct it. + +However, a very broad patent could have made all these issues +irrelevant. Imagine a patent with broad claims like these: + +- A communication process structured with narration that continues + through many pages. +- A narration structure sometimes resembling a fugue or improvisation. +- Intrigue articulated around the confrontation of specific + characters, each in turn setting traps for the others. +- Narration that presents many layers of society. +- Narration that shows the wheels of hidden conspiracy. + +Who would the patent holders have been? They could have been other +novelists, perhaps Dumas or Balzac, who had written such novels—but not +necessarily. It isn’t required to write a program to patent a software +idea, so if our hypothetical literary patents follow the real patent +system, these patent holders would not have had to write novels, or +stories, or anything—except patent applications. Patent parasite +companies, businesses that produce nothing except threats and lawsuits, +are booming nowadays. + +Given these broad patents, Victor Hugo would not have reached the point +of asking what patents might get him sued for using the character of +Jean Valjean, because he could not even have considered writing a novel +of this kind. + +This analogy can help nonprogrammers see what software patents do. +Software patents cover features, such as defining abbreviations in a +word processor, or natural order recalculation in a spreadsheet. Patents +cover algorithms that programs need to use. Patents cover aspects of +file formats, such as Microsoft’s OOXML format. MPEG 2 video format is +covered by 39 different US patents. + +Just as one novel could run afoul of many different literary patents at +once, one program can be prohibited by many different patents at once. +It is so much work to identify all the patents that appear to apply to a +large program that only one such study has been done. A 2004 study of +Linux, the kernel of the GNU/Linux operating system, found 283 different +US software patents that seemed to cover it. That is to say, each of +these 283 different patents forbids some computational process found +somewhere in the thousands of pages of source code of Linux. At the +time, Linux was around 1 percent of the whole GNU/Linux system. How many +patents might there be that a distributor of the whole system could be +sued under? + +The way to prevent software patents from bollixing software development +is simple: don’t authorize them. This ought to be easy, since most +patent laws have provisions against software patents. They typically say +that “software per se” cannot be patented. But patent offices around the +world are trying to twist the words and issuing patents on the ideas +implemented in programs. Unless this is blocked, the result will be to +put all software developers in danger. + +------------------------------------------------------------------------ + +This document was generated by *tonghuix* on *March 25, 2016* using +[*texi2html 1.82*](http://www.nongnu.org/texi2html/).\ |
