Re: Trademark policy
There are multiple factors that determine when trademarks can be used in AdWords ads and as keywords. For Text ads and keywords it differs.
Trademark terms used in keywords
Google will not investigate or restrict the use of trademark terms in keywords, even if a trademark complaint is received.
Trademark terms used in ad text
Google will investigate and may restrict the use of a trademark within ad text. Ads using restricted trademarks in their ad text may not be allowed to run. This policy applies worldwide.
