With the passage of the America Invents Act and evolving licensing issues and developments, A Practical Guide to Software Licensing for Licensees and Licensors, 5th Edition is an essential resource for lawyers who work with clients and business transactions in this arena. The latest Fifth Edition examines the fundamental issues that both licensors and licensees confront in the negotiation of a software license and, where appropriate, looks at relevant ancillary issues such as soft ware development, cloud computing, professional services, and maintenance and support. It primarily focuses on non-mass market agreements, since most "retail" or mass market "off-the-shelf" software is governed by non-negotiable "shrink-wrap," "browse-wrap," and "click-wrap" licenses. Nonetheless, the principles of software licensing are the same for shrink-wrap, browse-wrap, click-wrap, and custom-developed software.
