This presentation discusses attorney-client privilege for patent documents, global attorney client privilege issues, and the privilege from the “common-interest” doctrine. Most companies have a global portfolio of intellectual property in the form of patents, copyrights, and trademarks that are secured and maintained in different jurisdictions. In-house counsel face special challenges in managing the attorney-client privilege for these matters, especially during global disputes and investigations. Another challenge for controlling privilege arises in the context of mergers and acquisitions and these issues have to be addressed before and after the deal closes. Different jurisdictions differ in their approach, and corporate counsel should be aware of how privilege can be managed or transferred.
