Every life scientist practices due diligence. Whenever working with another group, acquiring the rights to a technology, or entering a round of financing, individuals take steps to make sure that interaction goes smoothly – the very premise underlying due diligence. When those interactions involve intellectual property (IP), the standard due diligence procedure is to execute nondisclosure agreements to protect the confidentiality of the information exchanged. But is this sufficient? If someone overhears intellectually protected information during a transaction, they can't "unlearn" what they now know about a competitor.
