In general, in a Due Diligence investigation, a patent professional will review the patent and patent file wrapper documenting prosecution of the patent application before the Patent Office and additionally should include analysis of information concerning the patent owner, named inventors, technical field or market. Because every case of Due Diligence is unique, it should be handled with an individualized approach on a patent-by-patent or portfolio-by-portfolio basis. Due Diligence is a tool that may be used to learn about a patent upfront, rather than purchasing a patent and finding out later on that the patent claims are worthless.
