WEB DEVELOPMENT FIRM GraphOn has sued Google for patent infringement in a Texas District Court.
The lawsuit alleges that Google's Base, YouTube, Blogger, Sites and AdWords unlawfully utilises patented technology.
The four patents in question were also named in an ongoing lawsuit by GraphOn against Yahoo, CareerBuilder, eHarmony and Match.com.
The Santa Cruz based outfit claims to have won ownership of the contested 6,324,538 and 6,850,940 patents via its 2005 purchase of Network Engineering Software (NES).
The 538 patent, which is particularly wide-ranging, covers such operations as "providing an HTML front-end entry process associated with the Web server" and "providing a Web server coupled to a computer network having a database operatively disposed within and accessible on [a] network”.
It should be noted that GraphOn successfully sued AutoTrader.com in January 2008 for allegedly infringing on the 538 and 940 patents.
L'Inq
Reading these patents, it's just a description of usenet through a web interface. 

Dejanews was doing this before the patent was registered. Google bought Dejanews and changed it into Google Groups. 

The only 'addition' is that the patent allows one to add information to existing information according to an authorization scheme, thus an implementation of access control lists. NNTP server implementations do a rough version of this (you're authorized or not), although it wouldn't surprise me if something akin to this was already present in Dejanews (you're authorized to post in some groups and not other (moderated) groups). Didn't Netscape's NNTP server add this to the existing NNTP code?

Shifting capital to the legal business, that's all this is about. 

Lies, damn lies and laywers
