Abstract: A register interest system receives from a potential acquirer of assets an indication that the potential acquirer is interested in acquiring rights in a specific asset that is not currently on the market. The register interest system stores indications that the potential acquirers are interested in specific assets. When a notification criterion has been satisfied, then the register interest system notifies the owner of the specific asset that one or more potential acquirers are interested in acquiring rights to that asset. The owner and a potential acquirer can then negotiate the purchase of the rights.
