Abstract: Disclosed herein is a method of providing protection against an unexpected change in value of an intellectual property asset, which includes: (a). obtaining a description of at least one intellectual property asset of a first party, (b). determining a value of the at least one intellectual property asset, (c). determining a cost of providing compensation for an unexpected change in value of the at least one intellectual property asset, and (d). offering to provide compensation for at least a portion of any unexpected change in value of the at least one intellectual property asset to a person with an interest in the first party. A corresponding data processing system, insurance proposal form and computer-generated insurance policy form also are disclosed. The method, system and forms of the invention can be used, for example, as part of a “due diligence” analysis in the context of the purchase and/or sale of intellectual property assets.
