Should I get a non-infringement opinion?

Answer

Non-infringement opinions are often most relevant when assessing the strength of a patent that may be asserted against your product(s).  They may be advantageous to further examine the strength of patents identified in a clearance opinion, owned by a known competitor or being considered for licensing or purchase.  Due to the expense involved in a non-infringement opinion, it is a very specialized tool used in particularly important/valuable decisions.
