A company's value can be measured using the sum of two types of resources: tangible assets, sometimes referred to as "hard" property, and intangible assets that includes intellectual property. Intellectual property is often protectable in the form of processes, formulas, devices, brands, artistic expression, etc. For many companies, the value of intangible assets is actually greater than the value of tangible ones. Thus, intellectual property can and should be protected by patents, trademarks, service marks, copyrights, franchises and trade secrets.
