This is entirely allowed within AdWords unless they are mentioning a trademarked term or brand name of yours in their ad copy. AdWords trademark policy. Although this year, Google did release a new policy that allowed advertisers to bid on trademarked terms for the first time.In fact, it is quite common to bid on and use competitor's name/products in AdWords ads.You can learn more on this here.
