What is a patent? Give examples of patents. What is the difference between process patents and product patents? How are GI tags related to patents?
In short
A patent is a government-granted exclusive right, usually for 20 years, over a novel, non-obvious and industrially useful invention; process patents protect the method, product patents the item itself. GI tags differ by protecting regional heritage such as Andhra Pradesh's Banganapalle mangoes and Tirupati laddu, not inventions.

Patent Definition and Criteria
Patents grant 20-year exclusive rights for inventions that are novel, non-obvious, and industrially applicable, as per the Indian Patents Act, 1970, which excludes certain areas like agriculture and biological processes to balance innovation with public interest.
Significant Cases and Impact
Diamond v. Chakrabarty (1980) expanded patent scope to genetically modified organisms, enabling biotech innovation; Novartis AG v. Union of India1 (2013) upheld public health by denying patents for minor drug modifications, illustrating India’s balanced patent policy.
Pharmaceutical and Biotechnology Patents
Post-TRIPS, India recognizes product patents, with Andhra Pradesh firms increasingly filing patents for new drug formulations; biotech patents cover inventions like genetically engineered microbes used in bioremediation.
Distinct but Complementary Protections
GI tags protect products tied to a region’s unique qualities, such as Andhra Pradesh’s Banganapalle mangoes and Kalamkari textiles, safeguarding traditional knowledge, while patents protect new inventions; both enhance economic value and prevent misuse.
Policy Significance
Protecting patents and GI tags supports innovation and preserves cultural heritage, promoting inclusive growth in states like Andhra Pradesh where agriculture and handicrafts are vital to the economy.
