Does Coca Cola have a claim in relation to the image of Santa Claus (which it has been using since the 1930s) in its Christmas advertising ?

Not so, unless it can produce concrete evidence that over the years, an association has developed in the mind of the average consumer between the Coca Cola fizzy drink and Santa Claus. Registering a trade mark to protect its Santa Claus image will be difficult, unless Coca Cola can show substantial evidence of such an association.

Any rights that Coca Cola may have are likely to be interpreted narrowly and limited to soft drinks.
