The approach to valuing a property depends on the specific circumstances and type of property to be valued.
A number of models exist that are useful to internally assess Intellectual Property that can help professionals make reasonable decisions in disciplines such as licensing and mergers and acquisitions.
They don't contain a way of dealing with critical accounting practices such as the principle of prudence or the concept of depreciation. Without a way to address these principles on a ledger, the valuations can't assure reliability and accuracy to other businesses in an accepted way.

The real estate industry could benefit from a universally accepted set of methods for accurately assessing intellectual property patents because it's a fundamental necessity to fully integrate your IP into your business. A reliable model does not exist today. Looking forward, what would be the tangible benefit of having such a method in place? The answer is the same benefits we currently think of today for having standard accounting practices-those having to do with regulation, risk and P&L.
Business managers also intuitively understand that Intellectual Property Services drive revenues and profits because these intangible assets are ultimately associated with products.
