The patent system has played a critical role in promoting the progress of science and technology since its inception by providing incentives to invent, to disclose, to design around and to invest. These incentives encourage the progress of science and technology in turn contributing to the economic development and prosperity of mankind. Though the patent system has played a critical role in the progress of science generally, its benefits have not been extended to medical methods. (The term ‘medical methods’ used herein after shall mean surgical, therapeutic and diagnostic methods of treatment except methods of administering drugs).
Most countries in the world have excluded methods of medical treatment from the scope of their patent systems. The Agreement on Trade Related Aspects of Intellectual Property Rights (TRIPS) under Paragraph 3 of Article 27 allows members to exclude diagnostic, therapeutic and surgical methods for the treatment of humans or animals from the scope of patentable subject matter. Similarly, US patent law allows methods of medical treatment to be patented but denies a remedy for its infringement, thus nullifying the right insofar as there is no enforceability. The nullification provision was hurriedly enacted in 1996 after wide dissatisfaction was provoked in the medical community by Pallin’s case. The European Patent Convention under Article 52 Clause 4 excludes from the scope of patentable subject matter methods of treatment of the human or animal body by surgery and therapy and diagnostic methods practiced on humans. The issue has been litigated to a considerable extent in the European courts. Instead of excluding medical methods completely, the judges have found In vitro diagnostic methods and cosmetic surgeries or therapies to be patentable.
The patent law of Japan also excludes methods of medical treatment from the scope of patentable subject matter. Part II of the Examination Guidelines for Patent and Utility Models provides extensive guidelines for patenting methods of medical treatment similar to European law. The Examination Guidelines permit patenting of In vitro diagnostic methods and cosmetic methods. China and India also explicitly exclude methods of medical treatment from patentability. Contrary to the world trend, Australian patent law does not exclude methods of medical treatment from patentability. In Bristol-Myers Squibb Co v F H Faulding & Co Ltd, the Federal Court of Australia in a case involving the validity of petty patents that claimed a method of administering the anti-cancer drug Taxol opined in dictum that a method of medical treatment is patentable. This court has validated the statute by positively allowing methods of medical treatment to be patentable. With the exception of Australia and perhaps a few other countries, most nations of the world exclude methods of medical treatment from the scope of patentable subject matter and in doing so they have taken away the incentives offered by the patent system. Such a policy has been adopted in light of the ethics inherent in the practice of medicine.
The American Medical Association Council on Ethical and Judicial Affairs is very concerned about the effects of patenting a medical method with regard to ethics inherent in the practice of medicine. (Ethical Issues in the Patenting of Medical Procedures at page 341, Food and Drug Law Journal, 1998). The AMA is worried that the duty of a doctor to disclose information about a medical method which has been laid down under Principal V of the Principles of Medical Ethics of the AMA will be restricted by the patent system. It is also afraid that the health care of the patient, which should be the basic concern of the doctor, will be driven by an economic motive if medical methods are patented. Furthermore, it fears that patenting a medical method will restrict clinical and academic access to that method. Additionally, the AMA is concerned that patenting a medical method will increase the financial burden on the patient if royalties must be paid, in addition to the doctor’s fee, for undergoing the patented method. Moreover, it is concerned that patient confidentiality and privacy may be hampered if the enforcement of the patent right involves identifying the patient who has undergone the patented method. Finally, it is apprehensive that the physician autonomy may be compromised if the doctor is motivated to maximize his profit as a patentee or a licensee.
These concerns of the AMA indicate a conflict between the incentives offered by the paten
