Ans. First, have clear objectives. What are the business objectives? What are the legal objectives? From this, derive the parameters of the patents you want to buy: number of patents, technical fields, evidence of use required, level of legal due diligence required. Then, set up a clear buying process. The process iterates through a funnel of successive screenings and negotiations with patent owners. Finally, make sure you have allocated budget, resources, and time for the project and do a sanity check with someone who has experience in these projects.
