Universal Drugs and Pharma Limited, a multinational pharmaceutical company, was incorporated and registered in Chennai. The company filed a patent application in India under the Patents Act, 1970, for its cancer drug Glivec (Imatinib Mesylate). The application sought to patent a beta-crystalline form of imatinib mesylate, claiming it to be a new form with improved bioavailability and efficacy. However, the Patent Controller of India rejected the application, stating that the drug did not meet the criteria for patentability under Section 3(d) of the Patents Act, 1970. The rejection was based on the ground that Section 3(d) prohibits the patenting of new forms of known substances unless they demonstrate enhanced therapeutic efficacy compared to the original compound. Universal Drugs and Pharma Ltd. challenged the decision before the Intellectual Property Appellate Board (IPAB), but the IPAB upheld the Patent Controller's decision. The company then filed an appeal before the Supreme Court of India, raising the following key legal issues : Whether the beta-crystalline form of imatinib mesylate qualifies for patent protection under Section 3(d) of the Indian Patents Act, 1970, given that the substance was already known but had been presented in a new form ? Whether the patentability criteria under Section 3(d) are consistent with international standards, or whether they are excessively restrictive ? In view of the above case study, answer the following questions in accordance with the provisions of the Indian Patent Act, 1970 : What are the rights of patentee under the Patent Act, 1970 ?
