Product Description
The field of software is awash in disputes. Market participants and analysts routinely disagree on how computer programs should be produced, marketed, regulated, and sold. On one subject, however, just about everyone can agree: the current intellectual property protection regime for software is a mess. At present, all of the traditional means of delimiting intellectual property--patents, copyrights, and trade secrets--are applied to software in one manner or another. Congress has even invented a new type of law for cases in which these may be insufficient, with the Digital Millennium Copyright Act.

The result is widespread confusion, along with the proliferation of nuisance suits. To date, the U.S. Patent and Trademark Office has granted more than 170,000 software patents, some on applications as commonplace as the pop-up window. Each of these patents gives the holder the right to sue others where no such right existed before, and so gaming of the system abounds. Software providers are forced to funnel millions of dollars annually into defending themselves against lawsuits rather than developing better software. The wave of litigation may end up stifling innovation and hobbling the open source movement, one of the most promising developments of recent years.

How did the situation arise? And where should we go from here? In Math You Can’t Use, Ben Klemens draws on his experience as both a programmer and an economist to tackle these critical issues. The answer to the first question, he explains, is simple: while patent laws are intended to apply to physical machines, software is something quite different. Software is not just another machine, and it is not Hamlet with numbers. It is a functional hybrid that can be duplicated at no cost, it is legible by computers in some forms and by humans in others, and it has a unique mathematical structure. All of these facts have to be taken into consideration in designing an appropriate intellectual property regime.

Designing such a system is a more difficult task. Klemens considers several alternatives, from modifying the existing rules to eliminating software patents in favor of a copyright-centered regime. Ultimately, he concludes, it is up to Congress to determine how software should be protected.

About the Author
Ben Klemens is a guest scholar at the Center on Social and Economic Dynamics at the Brookings Institution, where he writes programs to perform quantitative analyses and policy-oriented simulations.

5.0 out of 5 stars Why modern intellectual property rights are in a big mess - and how to fix the problem, May 20, 2006

By	Midwest Book Review (Oregon, WI USA) - See all my reviews

MATH YOU CAN'T USE: PATENTS, COPYRIGHT, AND SOFTWARE uses the author's experience as a programmer and an economist to describe why modern intellectual property rights are in a big mess - and how to fix the problem. MATH YOU CAN'T USE could also have been featured in our computer section, but is highlighted here for its wider-ranging interest to any college-level collection containing not only legal and computer books, but holdings considering intellectual property rights, issues, and development protection.

5.0 out of 5 stars a book you can use..., December 14, 2005

By	Zoe Konovalov - See all my reviews (REAL NAME)

Klemens has a knack for bringing humour and spirit to a subject most people might be inclined to regard as dull (i.e., software patent policy) - as well as explaining why addressing that subject is crucial. His background as a trained economist and practicing computer programmer gives him inside understanding of both the theoretical policy debate as well as its practical impact on the work of coding. The book is an invaluable resource - and you'll love the banana protective device diagram.

MATH YOU CAN'T USE
by Ben Klemens
pp. 181, Brookings Institution Press, Washington D.C., 2005


It is the ideas of inventors that drive the continuous technological progress in our societies. It then becomes important to ask if these inventors are getting the right incentives to innovate. What rights should an inventor be allowed to have over his invention/idea? Is his idea his alone? or is the idea anyone's who understands it? What does it mean to own an idea? The question of whether the "fugitive fermentation of an individual brain*" is a public good or the justifiably exclusive property of the individual brain is clearly an urgent one given the value we place on technological progress.

The subtleties of what constitutes an intellectual's excludable property and what constitutes the general public's property are usually outside the grasp of the general non-specialist crowd. Even amongst specialists (economists, computer people and so on) the discussions on the subject remain constrained by disciplinary boundaries and jargon in the blind men and elephant sort of way. Economists shy away from conversations with computer scientists who generously return the favour. Stated differently, the problem is that few economists write video games and even fewer video game writers would like to be spotted reading economics texts. This is a pity because if economists and software writers could talk to each other what else but the market for intellectual property in computer software would they talk about? The good news is that Klemens is at least, an economist and as he points out several times, he did write a video game.

To adequately understand the dynamics of the regulation of the market for software innovation, one needs to be a jack of several trades like, economics, computer science, law and even mathematics. In 'Math You Can't Use' Klemens brings this scarce combination of skills to bear upon this debate. His training as an economist as well as his facility with the arcane world of software programming puts him at a unique vantage point to survey the world of software patents. Add to this a knack for gentle humor and brevity of language and what you get is an immensely readable book that lays bare the economics, the math, the code and the legalese that underlie the mess that the world of patenting intellectual property in the software market involves.

Judging the book by its cover I expected the book to be a collection of mathematical theorems based on some abstract models of the software patenting business. I assumed that the theorems represented math I could not use simply because it was based on models that relied on unrealistic assumptions. Hence I expected the book to be the author's labor of love to mathematical reasoning that was in the end quite use-less for solving real world problems.

I was way off the mark there. The book's central claim is that there is a lot of math out there (theorems, lemmas, propositions, algorithms and so on) that you can't use because someone else came up with that math before you and now insists that the said math is his and his alone to cherish, protect and profit from. The main theorem that drives the ideas in this book is the Church Turing Thesis which allows us to show that a lot of software code is actually just a bunch of mathematical statements. Klemens creatively uses this thesis to argue his main points in the book.

'Math You Can't Use' actually reads like a generously embellished academic article which is a good thing as far as the pace at which ideas are presented in the book is concerned. For people interested in the area of software patents, this book will serve as a self-contained, down and dirty introduction to this area. From how computers work (for instance, how does a keystroke translate to text on the screen) to reporting rigorous economic theory, Klemens does an elegant job of walking the tightrope between academic rigour and readability. This book will be useful to students of the economics of innovation, computer scientists who read and policy makers.
