On opening day, a large backlit panel by the stand's entrance named three products: the Wave phone, the Tab tablet and, in the middle, the Note, which is between the two in size. By Sunday, an opaque board promoting the Wave had been stuck over the sign for the Tab, and staff on the stand refused to discuss the device or the changes. "That's confidential," said one.

Samsung's European PR director, Brendon Gore, was a little more forthcoming about the Galaxy Tab 7.7's fate.

"We took it away yesterday. It's not here," he said Sunday. "When we get an official communication from the Dusseldorf court, we can comment. That's all I can say."

Dusseldorf is where Apple is suing Samsung to stop sales of the 7.7's big brother, the Galaxy Tab 10.1.

European intellectual property laws allow companies to protect to the appearance of their products, in addition to the copyright, patent and trademark rights recognized in other jurisdictions. Apple claims the appearance of the larger Galaxy Tab is too similar to that of its iPad 2, the design of which is registered with the European Union's Office for Harmonization in the Internal Market.
