[Steve] Gibson, who early in the conversation makes it clear he believes in trademarks and copyrights and intellectual property -- although he sees software patents have become a problem -- and has even applied for patents when he's done consulting work, explains how patents get written and then stretched like taffy to be broader and stupider, and then he talks about his reaction to Microsoft's cl

Microsoft made waves this week with their GPLv2 contribution of virtualization code. On the other side of the coin, Microsoft continues to take issue with open source vendors over the issue of patents. One vendor that has called on Microsoft to be more open is Red Hat. In a blog post, Red Hat's legal team praised Microsoft's code contribution while asking Microsoft to change its stance on patents.

WE HAVE BEEN AWARE for a couple of years now that Red Hat too was discussing patents with Microsoft but no deal was ever signed other than the recent virtualisation collaboration. It involves no patents at all. This issue is entirely off the table, so what came to fruition is inherently different.

A look at some issues where Microsoft walks among patents and uses their enforcement to pursue its own goals

Open Invention Network (OIN) announced that three of the eight patents cited in Microsoft's lawsuit against TomTom have been posted for prior art review by the Linux community. The evidence is being compiled to convince the U.S. Patent and Trademark Office that the patents are invalid.

The $250 million Vonage burned through as a result of the patent lawsuit brought by Verizon et al provides yet another example of why patents for business processes implemented on computers (a.k.a. software patents) deserve to die. Verizon’s two successful “name translation” patents negate an open standard assembled by Cisco, Microsoft, IBM, Intel and Vocaltec via the VoIP Forum during 1996.

When Microsoft first sued TomTom for patent violations in TomTom's Linux-powered navigation devices, I wasn't sure how much of a fight TomTom would put up. Legally TomTom was between a rock and a hard place. You can't use restricted-use patents in GPLed software.

LAST WEEK was the last time we wrote about the T3 lawsuit, having pointed out that it is part of an innovative pattern. Over at Groklaw, in relation to the T3 lawsuit, Pamela Jones wrote: "Microsoft rivals end up defendants in litigation with Microsoft showing up somewhere in the background? How could that ever happen? Kidding...
