ETL patent case: Constellar and DataMirror let off off the hook; DataStage still in dock

Once again Vincent McBurney delivers a fantastic summary of the latest state of the Juxtacomm ETL patent case: SQL Server, DB2 and DataStage will fight out Data Integration Patent Infringement.

I'm most interested from the Constellar point of view - I first came across Constellar (then Information Junction) as a product on sale in late 1993 / early 1994 (before joining the company from Oracle in 1995), so it always seemed clear to me that it would qualify as prior art to Juxtacomm's 1998 patent. Oddly, it seems that the parties to the trial have agreed that Constellar Hub (and DataMirror Transformation Server) can be dropped from consideration; they won't be subject to damages - but equally they won't be considered as prior art. I don't understand that, but I guess the IBM lawyers must know what they are doing.

So, the case rumbles on, serving (if nothing else) to show how broken the US software patent system is.

SQLstream delivers instant data stream analysis of Mozilla 3.5 downloads

Here are a couple of posts that describe the download monitor/dashboard which is giving up-to-the-second statistics for downloads by country of the latest Mozilla release 3.5 (just about to top 5.5 million downloads since yesterday's launch). The dashboard has been put together with the help of my friends at SQLstream. Just don't try looking at this with Internet Explorer, as it doesn't support HTML5.
