Rights and Obligations of Patentee
Rights and Obligations of a Patentee
Introduction
A patentee is the person or entity granted a patent—a legal monopoly—over an invention for a limited period, typically to encourage innovation. The patentee enjoys exclusive rights but also has certain obligations.
Rights of a Patentee
1. Exclusive Right to Manufacture, Use, and Sell
The patentee has the exclusive right to make, use, sell, or license the patented invention.
No other person can manufacture or sell the invention without the patentee’s permission during the patent term.
2. Right to Assign or License
The patentee can transfer (assign) the patent rights to another person.
The patentee can also grant licenses (exclusive or non-exclusive) to others to use the patent in return for royalties or fees.
3. Right to Sue for Infringement
The patentee can initiate legal action against any party infringing on the patent.
The patentee can seek injunctions, damages, or accounts of profits.
4. Right to Import
The patentee has the exclusive right to import the patented product or processes.
Obligations of a Patentee
1. Working the Patent
The patentee is obliged to work (use or manufacture) the patented invention within the country.
Non-working of the patent may attract compulsory licenses or government intervention.
2. Disclosure
The patentee must disclose full details of the invention in the patent specification, enabling others to understand and reproduce the invention once the patent expires.
3. Paying Maintenance Fees
The patentee must pay periodic fees to keep the patent in force.
4. Non-Use or Misuse
The patentee must not abuse monopoly rights or use the patent in a manner detrimental to public interest.
Case Law Illustrations
1. Monsanto India Ltd. v. Coromandel Fertilizers Ltd.
Issue: Whether Monsanto’s patented process was being worked in India.
Held: Patentee has the obligation to work the patent locally. Mere import or sale of patented goods without local working can justify compulsory licenses.
2. Bayer Corporation v. Union of India
The case reaffirmed that the patentee’s rights are not absolute; they coexist with the public interest.
The patentee must ensure reasonable availability of the patented drug to the public.
3. Bajaj Auto Ltd. v. TVS Motor Company Ltd.
Affirmed that the patentee has exclusive rights and can restrain others from unauthorized use.
Also highlighted that infringement remedies protect the patentee’s rights.
Summary Table
| Rights of Patentee | Obligations of Patentee |
|---|---|
| Exclusive manufacture, use, sale | Work the patent in the country |
| Assign or license the patent rights | Full disclosure of invention |
| Sue for infringement | Pay maintenance fees |
| Import patented products | Avoid abuse of monopoly rights |
Conclusion
The patentee enjoys exclusive rights that incentivize innovation, but these rights come with responsibilities to work the patent and not impede public interest. The law balances the interests of the patentee with societal welfare, ensuring patents are not tools for undue monopoly but promote progress.
