Define "Homonymous Geographical Indications" and explain how they are treated under Section 10 of the Geographical Indications Act, 1999.

Homonymous geographical indications (GI) are those that are spelled or pronounced alike, but which identify products originating in different places, usually in different countries. In principle, these indications should coexist, but such coexistence may be subject to certain conditions. For example, it may be required that they be used only together with additional information as to the origin of the product in order to prevent consumers from being misled. A GI may be refused protection if, due to the existence of another homonymous indication, its use would be considered potentially misleading to consumers concerning the product's true origin. Section 10 of the Geographical Indications of Goods (Registration and Protection) Act, 1999 deals specifically with the registration of homonymous geographical indications. Permissibility of Registration: Section 10 allows the registration of homonymous GIs, provided that such registration does not mislead or confuse the public as to the true place of origin of the goods. Equitable Treatment of Producers: The Registrar is required to ensure equitable treatment to the producers concerned, having regard to the need to distinguish between the homonymous GIs. Consumer Protection: Adequate measures must be taken to ensure that consumers are not misled, including clear differentiation through labelling, packaging, or description. Conditions and Limitations: The Registrar may impose conditions or limitations on the use of homonymous GIs to clearly distinguish the goods originating from different geographical areas.
