MARKET SURVEYS - REQUEST FOR HELP

The IPKat's friend Chloe is doing some research into the use of market surveys in European trade mark law (whether in terms of assessing whether a sign has acquired distinctiveness or whether it is likely to be confused with an earlier trade mark). She's interested in the approach taken by the courts in (i) stipulating the methodology that should be used, (ii) admitting surveys in evidence and (iii) determining how great their evidential value is. She knows the position in the United Kingdom but would appreciate leads from elsewhere in Europe.

If you have any insights into market survey evidence that you'd like to share with Chloe, can you please send them here to the IPKat, who will pass them on.
