Whether or not it is impossible in theory, it is surely a difficult problem in practice. In other words, even if enclosure of the arable commons always produced gains (itself a subject of debate), enclosure of the information commons clearly has the potential to harm innovation as well as to support it. 26 More property rights, even though they supposedly offer greater incentives, do not necessarily make for more and better production and innovation—sometimes just the opposite is true. It may be that intellectual property rights slow down innovation, by putting multiple roadblocks in the way of subsequent innovation. 27 Using a nice inversion of the idea of the tragedy of the commons, Heller and Eisenberg referred to these effects—the transaction costs caused by myriad property rights over the necessary components of some subsequent innovation—as "the tragedy of the anticommons." 28 29
In short, even if the enclosure movement was a complete success, there are important reasons to believe that the intangible world is less clearly a candidate for enclosure, that we should pause, study the balance between the world of the owned and the world of the free, gather evidence. After all, even in physical space, "common" property such as roads increases the value of the surrounding private tracts. If there are limits to the virtues of enclosure even there, how much more so in a world of intangible and nonrival goods, which develop by drawing on prior creations? Yet the second enclosure movement proceeds confidently nevertheless—with little argument and less evidence. 30
To be sure, there is a danger of overstatement. The very fact that the changes have been so one-sided makes it hard to resist exaggerating their impact. In 1918, Justice Brandeis confidently claimed that "[t]he general rule of law is, that the noblest of human productions—knowledge, truths ascertained, conceptions, and ideas—become, after voluntary communication to others, free as the air to common use." 29 That baseline—intellectual property rights are the exception rather than the norm; ideas and facts must always remain in the public domain—is still supposed to be our starting point. 30 It is, however, under attack. 31
Both overtly and covertly, the commons of facts and ideas is being enclosed. Patents are increasingly stretched to cover "ideas" that twenty years ago all scholars would have agreed were unpatentable. 31 Most troubling of all are the attempts to introduce intellectual property rights over mere compilations of facts. 32 If U.S. intellectual property law had an article of faith, it was that unoriginal compilations of facts would remain in the public domain, that this availability of the raw material of science and speech was as important to the next generation of innovation as the intellectual property rights themselves. 33 The system would hand out monopolies in inventions and in original expression, while the facts below (and ideas above) would remain free for all to build upon. But this premise is being undermined. Some of the challenges are subtle: in patent law, stretched interpretations of novelty and nonobviousness allow intellectual property rights to move closer and closer to the underlying data layer; gene sequence patents come very close to being rights over a particular discovered arrangement of data—C's, G's, A's, and T's. 34 Other challenges are overt: the European Database Protection Directive did (and various proposed bills in the United States would) create proprietary rights over compilations of facts, often without even the carefully framed exceptions of the copyright scheme, such as the usefully protean category of fair use. 32
The older strategy of intellectual property law was a "braided" one: thread a thin layer of intellectual property rights around a commons of material from which future creators would draw. 35 Even that thin layer of intellectual property rights was limited so as to allow access to the material when that was necessary to further the goals of the system. Fair use allows for parody, commentary, and criticism, and also for "decompilation" of computer programs so that Microsoft's competitors can reverse engineer Word's features in order to make sure their program can convert Word files. It may sound paradoxical, but in a very real sense protection of the commons was one of the fundamental goals of intellectual property law. 33
In the new vision of intellectual property, however, property should be extended everywhere; more is better. Expanding patentable and copyrightable subject matter, lengthening the copyright term, giving legal protection to "digital barbed wire," even if it is used to prevent fair use: each of these can be understood as a vote of no confidence in the productive powers of the commons. We seem to be shifting from Brandeis's assumption that the "noblest of human productions are free as the air to common use" to the assumption that any commons is inefficient, if not tragic. 34
The expansion is more than a formal one. It used to be relatively hard to violate an intellectual property right. The technologies of reproduction or the activities necessary to infringe were largely, though not entirely, industrial. Imagine someone walking up to you in 1950, handing you a book or a record or a movie reel, and saying "Quick! Do something the law of intellectual property might forbid." (This, I admit, is a scenario only likely to come to the mind of a person in my line of work.) You would have been hard-pressed to do so. Perhaps you could find a balky mimeograph machine, or press a reel-to-reel tape recorder into use. You might manage a single unauthorized showing of the movie—though to how many people? But triggering the law of intellectual property would be genuinely difficult. Like an antitank mine, it would not be triggered by the footsteps of individuals. It was reserved for bigger game. 35
This was no accident. The law of intellectual property placed its triggers at the point where commercial activity by competitors could undercut the exploitation of markets by the rights holder. Copying, performance, distribution—these were things done by other industrial entities who were in competition with the owner of the rights: other publishers, movie theaters, distributors, manufacturers. In practice, if not theory, the law was predominantly a form of horizontal industry regulation of unfair competition—made by the people in the affected industries for the people in the affected industries. The latter point is worth stressing. Congress would, and still does, literally hand over the lawmaking process to the industries involved, telling them to draft their intra-industry contract in the form of a law, and then to return to Congress to have it enacted. The public was not at the table, needless to say, and the assumption was that to the extent there was a public interest involved in intellectual property law, it was in making sure that the industries involved got their act together, so that the flow of new books and drugs and movies would continue. Members of the public, in other words, were generally thought of as passive consumers of finished products produced under a form of intraindustry regulation that rarely implicated any act that an ordinary person would want, or be able, to engage in. 36
In the world of the 1950s, these assumptions make some sense—though we might still disagree with the definition of the public interest. It was assumed by many that copyright need not and probably should not regulate private, noncommercial acts. The person who lends a book to a friend or takes a chapter into class is very different from the company with a printing press that chooses to reproduce ten thousand copies and sell them. The photocopier and the VCR make that distinction fuzzier, and the networked computer threatens to erase it altogether. 37
So how are things different today? If you are a person who routinely uses computers, the Internet, or digital media, imagine a day when you do not create—intentionally and unintentionally—hundreds of temporary, evanescent copies. (If you doubt this, look in the cache of your browser.) Is there a day when you do not "distribute" or retransmit fragments of articles you have read, when you do not seek to share with friends some image or tune? Is there a day when you do not rework for your job, for your class work, or simply for pastiche or fun, some of the digital material around you? In a networked society, copying is not only easy, it is a necessary part of transmission, storage, caching, and, some would claim, even reading. 36 38
