The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a method (100) for producing natural dyes from underutilized indigenous fruits, including Prunus napaulensis (Khasi Cherry) and Viburnum foetidum (Stinking Viburnum). The method comprises collecting ripe pigment-rich fruits, washing them to remove impurities, and extracting natural pigments by boiling in water or environmentally benign solvent mixtures. The extract is filtered to obtain a clarified dye solution, which is applied to pre-treated natural fabrics such as cotton, silk, or wool. A natural iron-based mordant is used to enhance dye fixation and color fastness. The pigment may also be converted into a stable dye powder for storage and later use. This method provides an eco-friendly, biodegradable, and sustainable alternative to synthetic dyes, promotes utilization of local fruit resources, supports rural economies, and yields vibrant, naturally dyed textiles suitable for commercial and artisanal applications."
