1. Constitutional Foundations of Patent Law

(a) Article 21 – Right to Life

The Supreme Court has interpreted Article 21 to include:

• Right to health
• Right to access essential medicines

👉 Patent protection cannot restrict access to life-saving drugs.

(b) Article 14 – Equality Before Law

Patent laws must:

• Avoid arbitrary monopolies
• Ensure fair treatment

For example, unjustified extension of patents (evergreening) can violate equality.

(c) Article 19(1)(g) – Freedom of Trade and Profession

• Innovators have the right to carry on business
• But this is subject to reasonable restrictions in public interest

👉 Patent rights are not absolute.

(d) Directive Principles of State Policy (DPSPs)

• Article 39(b) – Resources distributed for common good
• Article 47 – Duty of the State to improve public health

👉 These principles justify limiting patent rights for public welfare.

2. Nature of Patent Rights in Constitutional Context

• Patents are statutory rights, not fundamental rights
• They grant temporary monopoly (usually 20 years)
• Purpose:
  • Encourage innovation
  • Reward inventors
  • Promote technological progress

⚖️ Constitutional balance:
Innovation incentives vs Public access

3. Key Doctrines in Patent Law

(a) Public Interest Doctrine

State can override patents for:

• Public health emergencies
• National interest

(b) Compulsory Licensing

Allows government to:

• Permit third parties to produce patented products

Prevents:

• Minor modifications being patented repeatedly
• Artificial extension of monopoly

8. Conclusion

Patent law in India is shaped by constitutional values of:
