Imagine sending a magazine article to 10 friends-making photocopies, putting them in envelopes, adding postage, and mailing them. Now consider how much easier it is to send that article to those 10 friends as an attachment to e-mail.

Or to post the article on your own site on the World Wide Web. The ease of modifying or copying digitized material and the proliferation of computer networking have raised fundamental questions about copyright and patent--intellectual property protections rooted in the U. Hailed for quick and convenient access to a world of material, the Internet also poses serious economic issues for those who create and market that material.

If people can so easily send music on the Internet for free, for example, who will pay for music? This book presents the multiple facets of digitized intellectual property, defining terms, identifying key issues, and exploring alternatives. It follows the complex threads of law, business, incentives to creators, the American tradition of access to information, the international context, and the nature of human behavior.

Technology is explored for its ability to transfer content and its potential to protect intellectual property rights. The book proposes research and policy recommendations as well as principles for policymaking. Brougher, Esq. But with the recent explosion of new scientific discoveries poised to transform public health and healthcare systems, costly and lengthy patent disputes threaten both to undermine the attempts to develop new medical technologies and to keep potentially life-saving treatments from patients who need them.

Intellectual Property and Health Technologies grounds readers in patent law and explores how scientific research and enterprise are evolving in response. Geared specifically to the medical disciplines, it differentiates among forms of legal protection for inventors such as copyrights and patents, explains their limits, and argues for balance between competing forces of exclusivity and availability.

Chapters delve into the major legal controversies concerning medical and biotechnologies in terms of pricing, markets, and especially the tension between innovation and access, including: The patent-eligibility of genes The patent-eligibility of medical process patents The rights and roles of universities and inventors The balancing of access, innovation, and profit in drug development The tension between biologics, small-molecule drugs, and their generic counterparts International patent law and access to medicine in the developing world As these issues continue to shape and define the debate, Intellectual Property and Health Technologies enables professionals and graduate students in public health, health policy, healthcare administration, and medicine to understand patent law and how it affects the development of medical technology and the delivery of medicine.

Information Technology Law is the ideal companion for a course of study on IT law and the ways in which it is evolving in response to rapid technological and social change. The fourth edition of this ground-breaking textbook develops its unique examination of the legal processes and their relationship to the modern 'information society'. Charting the development of the rapid digitization of society and its impact on established legal principles, Murray examines the challenges faced with enthusiasm and clarity.

Following a clearly-defined part structure, the text begins by defining the information society and discussing how it may be regulated, before moving on to explore issues of internet governance, privacy and surveillance, intellectual property and rights, and commerce within the digital sphere. Comprehensive and engaging, Information Technology Law takes an original and thought-provoking approach to examining this fast-moving area of law in context.

This text addresses critical and timely questions in patent law from a truly global perspective, with contributions from leading patent law scholars from various countries and various disciplines.

The rich scholarship featured reflects on a wide range of perspectives, offering insights and new approaches to evaluating key institutional, economic, doctrinal, and practical issues that are at the forefront of efforts to reform the global patent system, and to reconfigure geo-political interests in on-going multilateral, trilateral, and bilateral initiatives.

Information Technology Law examines how the law interacts with our actions in cyberspace and other elements of the information society. He does not seek to "wholly preempt the mathematical formula," since there are uses of his.

And he argues that the presence of specific "post-solution" activity -- the adjustment of the alarm limit to the figure computed according to the formula -- distinguishes this case from Benson and makes his process patentable.

We cannot agree. The notion that post-solution activity, no matter how conventional or obvious in itself, can transform an unpatentable principle into a patentable process exalts form over substance. A competent draftsman could attach some form of post-solution activity to almost any mathematical formula; the Pythagorean theorem would not have been patentable, or partially patentable, because a patent application contained a final step indicating that the formula, when solved, could be usefully applied to existing surveying techniques.

Dunbar, U. Yet it is equally clear that a process is not unpatentable simply because it contains a law of nature or a mathematical algorithm. See Eibel Process Co. Minnesota Ontario Paper Co. Proctor, supra. Radio Corp. Putting the question of patentability to one side as a preface to his analysis of the infringement issue, Mr. Justice Stone, writing for the Court, explained:. Funk Bros. Seed Co. Kalo Co. If there is to be invention from such a discovery, it must come from the application of the law of nature to a new and useful end.

Mackay Radio and Funk Bros. Indeed, the novelty of the mathematical algorithm is not a determining factor at all.

Whether the algorithm was in fact known or unknown at the time of the claimed invention, as one of the "basic tools of scientific and technological work," see Gottschalk v. This is also the teaching of our landmark decision in O'Reilly v. In that case, the Court rejected Samuel Morse's broad claim covering any use of electromagnetism for printing intelligible signs, characters, or letters at a distance.

In reviewing earlier cases applying the rule that a scientific principle cannot be patented, the Court placed particular emphasis on the English case of Neilson v. Harford, Web. Cases , , which involved the circulation of heated air in a furnace system to increase its efficiency.

The English court rejected the argument that the patent merely covered the principle that furnace temperature could be increased by injecting hot air, instead of cold into the furnace. That court's explanation of its decision was relied on by this Court in Morse:. We think the case must be considered as if the principle being well known, the plaintiff had first invented a mode of applying it. It would make the determination of patentable subject matter depend simply on the draftsman's art, and would ill serve the principles underlying the prohibition against patents for "ideas" or phenomena of nature.

The rule that the discovery of a law of nature cannot be patented rests not on the notion that natural phenomena are not processes, but rather on the more fundamental understanding that they are not the kind of "discoveries" that the statute was enacted to protect. Second, respondent assumes that the fatal objection to his application is the fact that one of its components -- the mathematical. In countering this supposed objection, respondent relies on opinions by the Court of Customs and Patent Appeals which reject the notion.

In re Chatfield, F. Even though a phenomenon of nature or mathematical formula may be well known, an inventive application of the principle may be patented. Conversely, the discovery of such a phenomenon cannot support a patent unless there is some other inventive concept in its application. Here it is absolutely clear that respondent's application contains no claim of patentable invention. The chemical processes involved in catalytic conversion of hydrocarbons are well known, as are the practice of monitoring the chemical process variables, the use of alarm limits to trigger alarms, the notion that alarm limit values must be recomputed and readjusted, and the use of computers for "automatic monitoring alarming.

To a large extent, our conclusion is based on reasoning derived from opinions written before the modern business of developing programs for computers was conceived. The youth of the industry may explain the complete absence of precedent supporting patentability. Neither the dearth of precedent nor this decision should therefore be interpreted as reflecting a judgment that patent protection of certain novel and useful computer programs will not promote the progress of science and the useful arts, or that such protection is undesirable as a matter of policy.

Difficult questions of policy concerning the kinds of programs that may be appropriate for patent protection and the form and duration of such protection can be answered by Congress on the basis of current empirical data not equally available to this tribunal. It is our duty to construe the patent statutes as they now read, in light of our prior precedents, and we must proceed cautiously when we are asked to extend patent rights into areas wholly unforeseen by Congress. As MR.

Latram Corp. We would require a clear and certain signal from Congress before approving the position of a litigant who, as respondent here, argues that the beachhead of privilege is wider, and the area of public use narrower, than courts had previously thought. No such signal legitimizes respondent's position in this litigation. A method for updating the value of at least one alarm limit on at least one process variable involved in a process comprising the catalytic chemical conversion of hydrocarbons wherein said alarm limit has a current value of".

In order to use respondent's method for computing a new limit, the operator must make four decisions. Based on his knowledge of normal operating conditions, he first selects the original "alarm base" Bo ; if a temperature of degrees is normal, that may be the alarm base. He next decides on an appropriate margin of safety, perhaps 50 degrees; that is his "alarm offset" K.

The sum of the alarm base and the alarm offset equals the alarm limit. Then he decides on the time interval that will elapse between each updating; that interval has no effect on the computation, although it may, of course, be of great practical importance. The computation of the updated alarm limit according to respondent's method involves these three steps:. Second, the solution of respondent's novel formula will produce a new alarm base B1 that will be a weighted average of the preceding alarm base Bo of degrees and the current temperature PIL of It will be closer to one or the other, depending on the value of the weighting factor F selected by the operator.

Third, the alarm offset K of 50 degrees is then added to the new alarm base B1 of to produce the updated alarm limit UAV of The process is repeated at the selected time intervals. In each updating computation, the most recently calculated alarm base and the current measurement of the process variable will be substituted for the corresponding numbers in the original calculation, but the alarm offset and the weighting factor will remain constant.

We use the word "algorithm" in this case, as we did in Gottschalk v. Claim 1 of the patent is set forth in the U. Examples mentioned in the abstract of disclosure include naphtha reforming, petroleum distillate and petroleum residuum cracking, hydrocracking and desulfurization, aromatic hydrocarbon and paraffin isomerization and disproportionation, paraffin-olefin alkylation, and the like.

The term "software" is used in the industry to describe computer programs.
