Example• Flav sells fruits with flavours induced into them. Sells fruits

like grapes, apples and so on with orange, mango and any other flavour induced into them. Flav's process is as follows:

• Frozen fruits are sorted, sliced and de-frosted;• Water and/or acid treatment is given to the fruits to remove

their natural flavour by removing sugars, acids and other water soluble ingredients;

• Fruits are then immersed in sugar syrup and other flavoured liquids for about three hours; and

• Air is blown on the fruits with force to dry them.

• Flav wishes to avoid patent risks in India. What should it do?
