With eCos assignments the contributor is also assigning the right to use the IP and any code which may be patented by the author in the future, as well as establishing true ownership of the code.
For example, I may write code that utilises some patented technology which requires that I license the technology in order to be able to use it in my device. I can contribute the copyright and license the code under whatever license I choose, but the fact that I am using a patented algorithm or suchlike means that anyone using the code is subject to licensing the patent from the owner. Not me the author of the code or person assigning the copyright, but the owner of the patent. Yes, software patents suck especially when the code is bleeding obvious, so sign up to http://stopsoftwarepatents.eu/ This is second third of the story and why it is important for contributed code to have a proper assignment before it can be contributed into eCos. Namely, to prevent the inadvertent introduction of unlicensed use of patented technology into eCos and to allow the continued use of the technology within eCos should it later be patented by the author. The final third is simply ensuring that the code really is theirs to assign. As mentioned previously, most code is originally owned not by the authors, but by the company that employs them. It also is there to prevent someone taking another's code (under another license, GPL for example), rework it for eCos, and to contribute it to eCos as their own. You cannot take GPL code and modify it for contribution to eCos as that modified code is derived, and therefore GPL'ed, and so does not satisfy the acceptance criteria for eCos. (Unless of course you are the original author and owner of the copyright of the GPL code and hence can relicense it under whatever license you like - e.g. YAFFS). -- Alex Schuilenburg -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
