Special rules of classification

All specific examples should be classified as additional information, e.g. a formulation example of a new sweetener in a beverage composition should be classified in the corresponding subclass in addition to the classification for the sweetener itself.

Drink compositions (formulations) are classified in A23L 2/38 or A23L 2/52. A23L 2/38 covers beverages that do not contain fruit or vegetable juices (which are classified in A23L 2/02).

A23L 2/52 covers beverages that may contain fruit or vegetable juices in addition to other ingredients.

If a beverage contains both fruit or vegetable juices and other ingredients, it will be classified in both A23L 2/02 and A23L 2/52.

Gas containing beverages, e.g. sodas, are classified in A23L 2/54.

When classifying in A23L 2/00, A23V 2002/00 indexing system should also be used when appropriate, in accordance with A23V 2002/00 classification rules.
