Last week saw significant developments in the row over whether the latest versions of Linux infringe SCO copyrights, with SCO announcing the pricing for its Intellectual Property Licence for Linux and IBM and Red Hat beginning legal proceedings against the company.
Until 15 October, SCO will be offering this new licence at a discounted price ranging from $699 (£435) for a processor to $4,999 for eight-processor servers.
Chris Sontag, senior vice-president and general manager at SCOsource, the intellectual property licensing division of SCO, said, "The licence ensures that customers can continue their use of binary deployments of Linux without violating SCO's intellectual property rights." SCO said one user had already purchased the new licence.
But SCO's chances of getting licence revenue from Linux users could be stymied as a result of legal action from IBM and Red Hat. In a statement following its counterclaim, IBM called SCO's actions "an attempt to profit from its limited rights to a very old Unix operating system by introducing fear, uncertainty and doubt into the marketplace".
IBM accused SCO of violating the Linux/GNU General Public Licence, under which it distributes Linux, by trying to charge licence fees for installed Linux. It also claimed SCO had violated at least four IBM patents.
UK users and the analyst community, which from the outset have been sceptical about SCO's claims, have become openly derisory following the unveiling of SCO's licensing model.
The general advice from analyst firms including Ovum, Butler Group and Bloor Research is not to buy a licence and take a "wait and see" approach. Simon Radcliffe, a consultant at Business Systems Group, said anyone that bought one of the £1,399 per-processor licences was "an idiot".
Robin Bloor, head of Bloor Research, believes IBM's counterclaim document may have "felled SCO in one stroke". He said the "coup de grace" of IBM's counterclaim is its assertion that SCO has infringed IBM's intellectual property rights and violated at least four IBM patents.
Following IBM's allegations, SCO issued a statement on its website which dismissed IBM's counterclaim filing as "an effort to distract attention from its flawed Linux business model".
In spite of the legal battle, the Linux community is already looking at how to resolve any potential copyright infringements. Linux distributors Red Hat and SuSe have claimed that replacing the contested Unix code that SCO claims was dumped "wholesale" into Linux would only take a few weeks, if not days.
At LinuxWorld last week, Linux developer Aduva unveiled a tool, Onstage 2.0, that it said would enable users to find and replace any "offending" Linux code on their servers.
