More patent palavers

This time it's Oracle who've filed an all-encompassing patent in the U.S. for a "self service system for web site publishing", or web content management system as it's otherwise known:

A web site creation and maintenance system permits distributed control and centralized management of a web site. [...] The web site system permits a site administrator to construct the overall structure, design and style of the web site. [...] The web site system permits content for the web site to originate from multiple content contributors. The publication of content is controlled by content owners. [...] The user, through use of only a web browser running on the user computer, transmits the parameter to the web site database. In response, the web site is updated at the database in accordance with the parameter.

Does this mean that Vignette, Documentum, Interwoven et al. are going to have to pay Oracle royalties for all the licenses they've sold?
