CAFC Won't Rehear Patent Case Of Editing XML
Found on Techdirt on Thursday, 01 April 2010
One of the more troubling patent rulings in the past year involved a Canadian company, i4i, that held a patent (5,787,449) that appears to broadly (very broadly) cover editing a custom XML document, separate from the presentation layer of a document.
Microsoft appealed to have the case reheard by the full panel of judges at CAFC, but that's now been rejected as well.
Meet the latest patent infringing technology: Notepad. Even the most simple text editor can be used to modify a XML document. How a judge could have granted this instead of laughing at i4i (who didn't even invent XML) is one of the unresolved mysteries.
