Structured due diligence tailored to your needs

Deep expertise across a wide range of technologies and industries

Due diligence of intellectual property relevant to a product or service can be helpful in a variety of circumstances. For example, when you are facing a dispute, investigating your freedom to operate, licensing-in technology, or buying, selling or investing in a company.

We can undertake comprehensive due diligence on the relevant IP portfolio and/or prior art, tailoring our service to your needs and budget. Our advice will identify, assess and weigh the risks and provide you with the clarity you need to make a decision with confidence in dealing with the intellectual property in question.
