Utilizing results typically provided by a professional patent searcher, we often can provide a clearance (a.k.a., "freedom to use") opinion.
A basic clearance opinion typically briefly distinguishes those patent claims that are most closely related to the major or critical features of the product or service of interest.
Advanced clearance opinions can include suggestions for permissibly "designing around" troublesome claims. Also, when designing around is undesirable, a non-infringement or invalidity opinion often can be provided.
