Ans. Probably not. Given the vast number of technical fields, it is unlikely that any broker would currently be selling patents of interest. It is more effective to do a patent search, find suitable patents, then contact the patent owners (either directly or through a third-party such as a broker) and ask if the owner would be willing to sell the patents of interest.
Ans. Buying patents is faster than applying for and obtaining patents. Therefore, buying patents can plug gaps in a company's patent portfolio and complement a company's research and development and patent application program.
Ans. Many companies purchasing patents do not want to disclose their name. Therefore, they work through a broker or other third-party to contact patent owners. Depending on the level of confidentiality required, the transaction can be structured so that the seller does not know the buyers indentity until just before the transaction closes, or even until after the transaction closes. We have various solutions to maintain buyer confidentiality.
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.
