Question

Under the Patents Act, 1970, a patent is granted to an inventor in India. Which of the following correctly reflects a limitation on the patentee's rights under the law?

• A. The invention cannot be used by the Government without permission
• B. The patent becomes void if used by a government authority
• C. The Government may use the invention for its own purposes without the consent of the patentee
• D. The patentee loses all rights once the invention is used by the Government

Hint:

In Intellectual Property law, exclusive rights are rarely absolute. Remember that the Patents Act allows Government use and compulsory licensing in exceptional situations to balance private rights with public interest.

Answer 1

The Correct Option is C

Concept: A patent grants exclusive rights to the inventor; however, such rights are not absolute. The Patents Act, 1970 recognizes certain situations where the Government may use a patented invention in the larger public interest without obtaining prior consent from the patentee.

Step 1: Understanding Government use provisions.
* Sections relating to Government use under the Patents Act permit the Central Government or an authorized person to use a patented invention for governmental purposes. * Such use may take place even without the consent of the patentee, although the patentee may be entitled to appropriate compensation as prescribed under the Act. * These provisions ensure that essential technologies can be utilized for public welfare, national security, public health, or other governmental functions.

Step 2: Examination of the options.
* Option (A) is incorrect because Government use is specifically permitted under the Act in certain circumstances. * Option (B) is incorrect because Government use does not invalidate or void the patent. * Option (D) is incorrect because the patentee continues to retain patent rights despite such governmental use. * Option (C) correctly states the statutory limitation on the patentee's exclusive rights.

Patent rights are exclusive, but they remain subject to the Government's statutory power of use in the public interest.

Answer 2

This question is about the built-in limitations that the Government-use provisions of the Patents Act, 1970 place on an otherwise exclusive patent right. Checking each option against what these provisions actually say identifies the correct limitation.

1. The invention cannot be used by the Government without permission: This is the opposite of what the Act provides. The Act expressly reserves to the Government the right to use, or have used on its behalf, any patented invention for its own purposes, without needing the patentee's prior permission, so this option misstates the law.
2. The patent becomes void if used by a government authority: Government use does not affect the validity of the patent at all. The patentee continues to hold a live, enforceable patent even while the Government exercises its statutory right of use, so this option is incorrect.
3. The Government may use the invention for its own purposes without the consent of the patentee: This directly reflects the statutory scheme, which allows Government use, and use by any person authorised by the Government, for purposes of the Government, without the patentee's consent, subject to the patentee's right to compensation in appropriate cases. This matches the statutory limitation being tested.
4. The patentee loses all rights once the invention is used by the Government: Government use is a limited, purpose-specific carve-out; it does not strip the patentee of the underlying exclusive rights, which continue to operate against everyone other than the Government acting within the statutory carve-out. This option overstates the effect of Government use.

Only the third option correctly states the statutory limitation, that Government use for its own purposes does not require the patentee's consent, while the patent itself remains valid and the patentee's other rights remain intact.

Hence, the correct answer is The Government may use the invention for its own purposes without the consent of the patentee.
