Advertising on google adwords (Question to PrestaShop Developer Team)

[metu]

I have given an advertising on google adwords. My keywords are "prestashop themes, prestashop templates, etc." However my ads cannot run, because it says "A trademarked term is preventing your ad from showing."

I want to ask; if prestashop team have a demand from google about keyword "prestashop" is a trade mark and people having prestashop template website cant give advertisement on google??? Or if there is such a want, How can I give advertisement on google for keywords including "prestashop"? (do u give a permission to prestashop template or module site owners)
