A Proprietary Technology encapsulates an invented process of manufacturing a product which is unique to a business or an individual. Such technologies are normally protected by a patent, copyright or other forms of intellectual property rights. With the legally backed propriety rights, others cannot replicate the process. In business valuation analysis, a proprietary technology qualifies as intangible assets which present measurable economic benefits to the owner. Intangible assets are a class of assets without physical form with intrinsic value to the owners. To estimate the fair market value of Proprietary Technology, business valuators apply techniques under income, market and asset methods, a situation made possible by the fact that Proprietary Technology can be recognised and the associated economic benefits reliably measured.
