RWarrior(fobw) writes "PJ reports at Groklaw that Oracle has sued well-known patent troll Lodsys, asking for declaratory judgement in the Eastern District of Texas that Oracle and its customers don't need Lodsys licenses, and that Lodsys patents are invalid anyway. 'It seems that Lodsys has been going after Oracle customers, and they in turn have been asking Oracle to indemnify them. Lodsys, methinks, has made a mistake. One doesn't go after Oracle's money. No. No. Never a good plan. I suspect Oracle will go for damages, tripled, and all their expenses, legal fees, etc. when this is over.' PJ also points out that which companies are the good guys and which are the bad guys depends on which case you're looking at. "
