A Christchurch Coffee Company has caused some confusion - it's logo is almost identical to that of the Orthodox Union's symbol of Kashrut.
The "OU" Symbol is almost universally sought by Kosher travellers as a sign that food is produced to the standards of Kashrut. But make no mistake, this is not a religious symbol, this is the symbol of a business.
I feel some sympathy to the coffee company. The Jewish community is virtually non-existent in Christchurch, and they probably had no idea that this was a registered trademark. But ignorance is not really a defence - imagine if they used the Golden Arches, for example.
I'm sure that common sense can prevail, and Underground Coffee could modify their logo - perhaps to add Serif marks, or a "G" that makes it different enough to be easily distinguished.
More information listed here at Fairfax. It's clear that damages are not being sought, but OU is a worldwide trademark. If Underground started producing Coffee for supermarkets, or exporting, then this could be a major headache for consumers.
