Understanding Patent Revocation under Patent Act, 1970

The Patent Act, 1970, outlines the procedures and conditions related to patents in India. A crucial aspect is the process by which a granted patent can be invalidated or cancelled, which is known as revocation. The question specifically asks for the section under the Patent Act, 1970, that deals with the revocation of a patent.

Section 64: Grounds for Revocation

Section 64 of the Patent Act, 1970, explicitly addresses the revocation of patents. It provides a list of specific grounds upon which a patent can be revoked by the High Court or the Controller of Patents.

The key grounds for revocation under Section 64 include:

• The patent was obtained wrongfully, such as by fraud or misrepresentation.
• The grant of the patent was in contravention of the provisions of the Act.
• The complete specification does not sufficiently and fairly describe the invention or the method by which it is to be performed.
• The invention, as claimed in the complete specification, is not patentable under the Act.
• The person applying for the patent was not the true inventor or did not derive the invention from the true inventor.
• The claims of the patent are not clearly and distinctly claimed, or they are not supported by the description.

Therefore, Section 64 is the primary section dealing with the revocation of patents.

Analysis of Other Sections

To confirm why Section 64 is the correct answer, let's briefly look at the other options:

• Section 10: Conditions for patentability - This section lays down the requirements for an invention to be considered patentable, such as novelty, inventive step, and industrial application. It does not deal with revocation.
• Section 84: Compulsory licenses - This section relates to the provisions for granting compulsory licenses in certain circumstances, allowing others to use the patented invention. It is not related to patent revocation.
• Section 113: Conflict between patentees - This section deals with situations where multiple patent applications or patents conflict, typically concerning the same invention. It does not cover the general revocation of a patent.

Based on the scope defined in the Patent Act, 1970, Section 64 is the designated section for matters concerning the revocation of a patent.
