1. Identifying Intangible Assets and Intellectual Property
To qualify as an intangible asset, the owner should be able to specifically identify and describe the asset, and it should be subject to legal protection.
Moreover, one should be able to privately own the asset and legally transfer or sell it to another party.
For an intangible asset to have quantifiable value from an appraisal perspective, it should possess certain economic attributes or characteristics in addition to those that indicate legal existence.

2. intangible assets
There are five general classifications of intellectual property, including:
Trademarks
Copyrights
Patents
Know-How
Trade secrets
Intellectual property differs from other intangible assets in that it is the result of conscious creative activity.

3. Examples of Intangible Assets
Examples of intangible assets some businesses may possess:
Trademarks, trade names, brand names, logos
Process patents, product patents, technical know-how
Copyrights, blueprints, trade secrets
Computer software and automated databases
Customer lists, customer contracts, open purchase orders
License and franchise agreements
Trained and assembled workforce, employment agreements
Leasehold interests, mineral rights, air and water rights
Going concern goodwill, professional practice goodwill

4. Intellectual Valuation
Methods that value intellectual property under the income approach may by focus on:
The greater level of income realized by the owner of the intellectual property compared to not owning the property (leading to higher profitability).
The lower levels of costs realized by the owner of the intellectual property compared to not owning the property (also leading to higher profitability).
“Relief From Royalty” methods, which are based on a hypothetical royalty payment that the owner of the intellectual property would be willing to pay or otherwise would have to pay to a third party

5. Income Approach
The subject patented technology allows the business to generate greater profits every year compared to not owning the patent.
The added profitability adds value to the business.

6. Market Approach
Comparable patent sales are related to the industry in which the subject business operates.
The value of the comparable transactions are determined.

7. Cost Approach
The cost of developing the patent (including employee labor hours, testing costs, design costs, etc.) are determined.

8. Intellectual Property Losses
Research has estimated the value of trade secret theft in the US to be 1% to 3% of its GDP, the equivalent of US$200 billion to $550 billion per year.
Extrapolating that estimate to other advanced industrial economies could put the global cost of trade secret theft in the trillions.
