Introduction to Patents

A patent grants exclusive rights to an invention (product or process) for 20 years. It prevents commercial use, distribution, or sale without the owner's consent.

• Owners can license or sell patent rights.
• After expiry, the invention enters the public domain.
• Patent owners must disclose information about their invention to foster innovation.

Patent Infringement

A patent grants exclusive rights to distribute or sell an invention in India. Infringement occurs when these rights are violated. Copying a patented invention can lead to legal action.

Examples of Infringement:

• Imitating an invention
• Creating an immaterial variation

Claims by Godrej Soaps Ltd. (Respondent)

• A multinational company with 60 years of experience in soap manufacturing in India.
• Utilizes various soap admixtures but hasn't patented them, claiming they aren't inventions.
• Disputes the validity of the plaintiff's patent.
• Argues that an injunction would stifle competition.

Problems Identified

• Hindustan Lever Ltd. hasn't patented the specific admixture or substance.
• Injunction during large-scale soap production.

Proposed Solutions

• Claims cannot be infringed if the combination of substances differs.
• Godrej's admixtures differ from Hindustan Lever Ltd.'s.
• Therefore, Hindustan Lever Ltd.'s infringement claim is potentially invalid.
