Current developments in Open Source Software

Open Source Software (OSS) has hit the mainstream in recent years and its scope is set to increase. Best seen as a range of associated licensing techniques, there are many different types of OSS licences. Coupled with a lack of settled case law and rapidly developing market practice, legal interpretation of the OSS world presents challenges to lawyers. Of the 'top 20' OSS licences, the GPL is the most commonly used and among the most radical in legal effect. The GPL's legal radicalism centres on its Article 2(b) concept of 'copyleft'. Copyleft is an inheritance requirement to pass on the GPL's terms to other software that 'contains' or is 'derived from' the initially used GPL software. I illustrations of Article 2(b) issues from the Linux and Java worlds are provided. Current case law (such as it is) is then overviewed. Finally, contractual and policy implications of OSS governance are then reviewed as the increasing uptake of OSS in the organisation is mirrored in the growing importance of OSS governance. © 2009 Kemp Little/LLP.
