On August 2, Tucson-based company Research Corporation Technologies (RCT) won a reversal of a federal court decision that had found RCT's six patents-in-suit unenforceable due to "inequitable conduct" and denied RCT's charges of patent infringement by Microsoft. The U.S. Circuit Court of Appeals had also granted Microsoft a summary judgment finding the patents invalid and non-infringed.
RCT has also licensed its "Blue Noise Mask" digital imaging patents to HP, Lexmark, and Epson.
Microsoft continues to maintain that the RCT patents are invalid and not infringed by Windows or Office.
It is a wonder Microsoft has time to create more software and such with all of the lawsuits filed against them for patent infringement. It is a real eye opener reading your profound blog.
