Movement trade marks

My old mate Russell Waters, writing in the IPNow blog, tells us that in Australia

Recent amendments to the Trade Mark Examiner’s Manual now make specific reference to moving images, holograms and gestures as trade marks.

Movement marks and holograms also feature in the UK IPO’s manual of trade marks practice, though it has nothing to say about gestures. We had a gesture trade mark on the register, once, and I still refer to it when I present courses, though it seems to have disappeared without trace.
