Performing a trademark search prior to filing an application is critical as you can avoid filing an application that may be problematic.  We perform comprehensive US and foreign trademark searches.  Our searches go beyond simply providing a search report.  Our searches include a follow up consultation with a trademark attorney to discuss the search results and to dig into the prosecution history of the results.  For example, knowing if a problematic mark has received an office action or will issue soon could impact the adoption of a trademark.
