PATENT PROBLEMS: The patenting of scientific discoveries may be necessary in order to protect some scientists' intellectual property, says British immunologist Cesar Milstein; but he also cautions that the practice of patenting is often unfair and actually dangerous to the health of curiosity-driven research. TI : Patents On Scientific Discoveries Are Unfair And Potentially Dangerous AU : CESAR MILSTEIN TY : OPINION PG : 11 Many of us still remember a time when the idea of taking out a patent was far from foremost in our minds. In those days, scientists working in universities and government-sponsored institutions were driven not by the patentability of their ideas, but rather by pure scientific considerations. Patents were rare, more an afterthought than a preliminary consideration. The advent of modern biotechnology has brought about a considerable change, so that now, even among the most curiosity- driven scientists, the question "Should I take out a patent?" becomes an issue whenever a new discovery or a new procedure becomes experimentally successful. If the scientist in question is better acquainted with current business practices, he or she may well be tempted to take out a patent even before the results of the experiments are certain. Otherwise, there is a very real risk that someone else will patent the idea, and that the experiments will be used only to validate the other person's patent. Recent developments in connection with the controversies surrounding the patenting of DNA sequences go even further. It is becoming a matter of high priority for the scientific community to take a careful look at the issues involved. A recent pronouncement of the International Council of Scientific Unions (ICSU) urging the patenting authorities to consider the danger in allowing pat-ents of nucleic acid sequences per se is a good start in the right direction. And yet the problem goes deeper. Different countries have different concepts in terms of patenting principles--for example, first to "invent" (United States) vs. first to patent (Europe); a period of grace (U.S.) vs. no disclosure rules (Europe). Worse still, lawyers and scientists do not speak the same language or use the same criteria: What is an obvious extension of previously established facts (as far as scientific judgment is concerned) can also be construed as novel (in legalistic terms), and thus merit patenting. At the other extreme, leaps in scientific knowledge that do not present any obvious practical implications today may be the foundation for further developments and lead to innumerable patents in the future. Good examples are the discoveries of somatic cell hybridization and of restriction phenomena in bacteria, both major advances in basic science whereby eventual developments could not be predicted and were therefore unpatentable. Without these advances, biotechnology would not be what it now is. So, patents are basically unfair. But perhaps they are necessary for the development of products that will ultimately benefit society. Without them (we are told) companies would not be prepared to spend the amount of money required for such developments. The new element in this equation, however, is that the complexity and multiplicity of overlapping pat-ents in the field of biotechnology is creating such havoc that the counterargument--that patents are beginning to inhibit the development of new products--should begin to be considered with the seriousness it deserves. It remains a fact that the specter of patents is not only introducing new tensions in the scientific community, but also having serious and undesirable effects on basic developments that largely rely on curiosity-driven research. Cesar Milstein is an immunologist at the Laboratory of Molecular Biology, Cambridge, England.
