A key part of value creation in an intellectual property portfolio is an ongoing process of detailed review and analysis of the patent estate and freedom to operate. This can fulfil a variety of functions by delivering a report for an investor pre-financing, as part of M&A, MBO, acquisition or divestment. The benefit of a commercially designed intellectual property plan created as early as possible in the life of a business means that the building blocks are available to meet any eventuality or opportunity without the need to spend money reacting as opportunities arise. From the aspect of investors this versatile due diligence activity is invaluable to potential investors of all sizes, law firms and companies evaluating acquisition targets.
