Correct option is A

The correct answer is (A) 2004

Explanation:
• The Patents Act, 1970 is the primary legislation for patents in India.
• To comply with the TRIPS (Trade-Related Aspects of Intellectual Property Rights) agreement, India had to amend its laws.
• The first amendment was in 1999, the second in 2002.
• The third amendment was introduced via the Patents (Amendment) Ordinance in December 2004, which was later replaced by the Patents (Amendment) Act, 2005.
• This third amendment was crucial as it introduced "Product Patents" for food, drugs, and chemicals, moving away from only "Process Patents."

Information Booster:
• Before 2005, India only allowed process patents for pharmaceuticals, which enabled the growth of a strong generic drug industry.
• The 2005 amendment (originating in late 2004) also introduced provisions for Compulsory Licensing and Pre-grant/Post-grant opposition.
• Section 3(d) of the Act is famous for preventing "evergreening" of patents.

Additional Knowledge:

• 2002 (Option II): This amendment increased the term of patents to 20 years for all inventions.
• The Indian Patent Office is headquartered in Kolkata with branches in Delhi, Mumbai, and Chennai.
