The legal opinion provided by an attorney to a trademark owner or prospective trademark owner that identifies the legal risks associated with using a particular trademark. Such risks might include, for example, the possibility of infringing or diluting an existing mark and hence being sued, and the likelihood that an application for trademark registration will be rejected. The legal opinion of an attorney can serve not only as immediate advice on the risks in adopting a given mark, but if the opinion is written, which most are, you may be able to deter companies appearing in the opinion from suing for infringement by showing them that at least one attorney has already decided the marks are not confusingly similar. It is important to note, however, that while attorneys are trained to be objective, the inherent subjectivity of trademark law suggests that a second legal opinion is a very good idea if there is any question about the availability of a mark or about conflicts between marks.
