1.The Indian Patents and Designs Act, 1911, (Act II of 1911) replaced all the previous Acts of patents in India.This Act brought patent administration under the management of Controller of Patents for the first time.
2.After Independence, it was felt that the Indian Patents & Designs Act, 1911 was not fulfilling its objective. It was found desirable to enact comprehensive patent law owing to substantial changes in political and economic conditions in the country. Accordingly, the Government of India constituted a committee under the Chairmanship of Justice (Dr.) Bakshi Tek Chand, a retired Judge of Lahore High Court, in 1949 t o review the patent law in India in order to ensure that the patent system is conducive to the national interest.
3.Based on the recommendation of the Committee, the 1911 Act was amended in 1950 in relation to working of inventions and compulsory licence/revocation.
4.A bill was introduced in the Lok Sabha on 21st September, 1965, which however lapsed. In 1967, again an amended bill was introduced which was referred to a Joint Parliamentary Committee and on the final recommendation of the Committee, the Patents Act, 1970 was passed. This Act repealed and replaced the 1911 Act so far as the patents law was concerned. However, the 1911 Act continued to be applicable to designs. Most of the provisions of the 1970 Act were brought into force on 20 th April 1972 with publication of the Patent Rules, 1972.
