An asset can have several quite independent values: a Tax valuation, a Book valuation (what the organisation says is its value on the Balance Sheet) and finally a Market Value.
The Market value of any asset is what someone would pay to buy the asset, provided that is also at least what the current owner would take to sell it. The current and prospective owners have quite different sets of information available to them, and striking a deal depends upon there being some overlap between the buyers' and sellers' valuations.
There is little point staring across a (metaphorical) table at someone whose view of an asset's value is fundamentally different to yours. AcuteIP provides a service to value intangible assets based on all available information (including sources you have not thought of), in a way that is transparent to both potential partners.
