Novell completed its acquisition of Linux distributor SuSE in January and has launched an indemnity program similar to Hewlett-Packard's, offering customers protection against future copyright challenges for the Linux systems they sell. Novell has also claimed ownership of the AT&T Unix source code.
In mid-January, Red Hat announced an Open Source Assurance program, which contains two items of interest. With an Intellectual Property Warranty, Red Hat promises to replace any software deemed to violate intellectual property law in a manner that won't be disruptive to the customer. Sounds good--but as a customer, I'd rather have indemnity than assurance. The program also includes an Open Source Now Fund, which sets aside money for legal fees for companies involved in the development of software under the Linux GPL (General Public License).
