To be patentable, an invention must be susceptible of industrial application, new and involving an inventive step. Certain types of inventions are expressly excluded, namely:
a discovery, scientific theory or mathematical method;
an aesthetic creation;
a scheme, rule or method for performing a mental act, playing a game or doing business, or a programme for a computer;
the presentation of information;
a method (not a product - a substance or composition for use in such method) for treatment of the human or animal body by surgery or therapy and a diagnostic method practised on the human or animal body;
an invention the publication or working of which would be contrary to public order or morality;
a plant or animal variety or an essentially biological process for the production of plants or animals, other than a microbiological process or the products or the products of such a process. (However, separate provision has been made for the protection of plant varieties under a separate Plant Varieties Protection Ordinance which was passed in May 1996 but has not yet been brought into effect.)
The novelty requirement raises an interesting issue, in that UK patents have a novelty standard encompassing worldwide use as well as worldwide publication, whereas the Chinese Patent Office has a standard of domestic use (but worldwide publication). Under the new regime, it is therefore possible to register a valid patent for an invention in China which had been used but not published outside China and so would be invalid if registered in the UK. Such a patent will however be invalid in Hong Kong under the new legislation, which expressly adopts a standard of worldwide use.

This article enunciates the recent, much awaited, and landmark judgment delivered on September 16, 2016 by Hon'ble Delhi High Court throwing light on the important provisions of the Copyright Act, 1962.
The Patents Act 1970, along with the Patents Rules 1972, came into force on 20th April 1972, replacing the Indian Patents and Designs Act 1911. The Patents Act was largely based on the recommendations of the Ayyangar Committee Report headed by Justice N. Rajagopala Ayyangar. One of the recommendations was the allowance of only process patents with regard to inventions relating to drugs, medicines, food and chemicals.
The Policy stresses on the need for a holistic approach to be taken on legal, administrative, institutional and enforcement issues related to IP.
