A patent portfolio is a collection of patents owned by a single entity, such as an individual or corporation. The patents may be related or unrelated.
The monetary benefits of a patent portfolio include a market monopoly position for the portfolio holder and revenue from licensing the intellectual property. Non monetary benefits include strategic advantages like first-mover advantages and defense against rival portfolio holders.
Because patents have a fixed lifespan, elements of a portfolio of patents constantly expire and enter the public domain.
Market value and evaluation
The value of a corporation's patent portfolio can be a significant fraction of the overall value of the corporation. Ocean Tomo LLC, for example, has recently introduced an index of corporations whose market value is governed in large part by their patent portfolio value. The index is called "Ocean Tomo 300® Patent Index". [1]
As another example, the European Patent Office has recently acquired IPscore, a software application, developed by the Danish Patent and Trademark Office, the purpose of which is to estimate "the economic value of patents and development projects". [2]
