ABSTRACT
The concept of patents has changed the way businesses operate. The grant of a patent allows any corporation to operate in the relevant market with a feeling of comfort otherwise unavailable to the corporation. One piece also reduces the economic value of the blockage strategy, as it is all the more possible that one's rival may try to circumvent one's blocking strategy by developing a solution. The cross license, when issued for a multitude of patents by the patentee, becomes another feature called the portfolio license. The entire collection of the patentee's patents is given in license in return for a fixed license fee. Revenue neutral licenses depend on a circular trading concept. All the business rivals license to each other all of their relevant patents for exploitation. Patents pooling reduces overall costs of repetitive and patent-circumventing research and development (R&D).
