Linux Patent Infringement Lawsuit Filed Against Red Hat/Novell
walterbyrd writes "Just months after the last nail in SCO's case, and on the same day as Red Hat's brave words about patent intimidation, a company filed the first patent suit against the Linux operating system. IP Innovation LLC filed the claim against Red Hat and Novell over U.S. Patent No. 5,072,412. PJ points out there is prior art here: 'You might recall the patent was used in litigation against Apple in April 2007, and Beta News reported at the time that it's a 1991 Xerox PARC patent. But Ars Technica provided the detail that it references earlier patents going back to 1984.'"
Those patents cover GUI patents, they apply to window managers that provide virtual desktops. It has nothing to do with the Linux Kernel itself.
It could be more difficult than usual; IANAL, but one thing that often happens after a patent infringement claim is a counter-claim with another patent, and then a cross-licensing agreement is often reached to settle the situation. However, this may be a case of patent trolling, where this means of protection doesn't work because the company who owns the original patent doesn't actually make anything related, and therefore cannot have any related patents. Of course, attacking the patent itself or showing that it's inapplicable still work, I think (and hope). Besides, software patents can't be enforced or don't exist in many countries (particularly in Europe), so a patent attack would be unlikely to get rid of Linux altogether.

All patents have to (or at least are supposed to) list similar but distinct prior art, in order to distinguish their own unique invention. You can't point to the disclosed prior inventions on the patent application itself and go "Ah hah, gotcha!". I mean, unless you like to pretend that you're a lawyer on Slashdot.
If you were blocking sigs, you wouldn't have to read this.
Apparently IP Innovations LLC is a subsidiary of Acacia, one of the largest patent troll groups around according to Troll Tracker. IP Innovations has only been around since 2002 with 5 employees and revenues less than $1 million, according to their listing on Fedvendor, so it's quite perverse to be trying to sue over a patent issued to somebody else in 1991...
Forget thrust, drag, lift and weight. Airplanes fly because of money.
Maybe.
IP Innovation LLC is a subsidiary of Acacia, and Acacia recently appointed Brad Brunell, who worked for 16 years at Microsoft as general manager, intellectual property licensing. He's now a senior vice president. Other ex-Microsoft executives have also recently migrated to Acacia.
Acacia are known as patent trolls.

It's actually not as vague as "multiple windows visible for application" which Clippy would violate. The patent is on the ability of share windows/views between multiple workspaces. So the fact that your application toolbar / "start menu" shows up in multiple workspaces would be a violation of this patent. FYI, ctl-alt-left,right arrow to switch between workspaces in gnome. Also right click the window-title "always on visible workspace" option is a violation of this patent. It's disgusting that companies can buy these patents for the sole purpose of suing people. If Redhat disabled this feature I doubt it would impact a significant portion of the users. Most window managers implement it in some form.
Wow, after hearing that Acacia has anything to do with this, I am not surprised at all. I worked in the distance education department for a University a few years back. At that time, they were making rounds among the education industry, and sending letters asking for several hundred thousand dollars, or 5% of all profits made from a series of patents.
The patents? "A system of distributing video and/or audio information employs digital signal processing to achieve high rates of data compression" over cable, tv, telephone, and as they were implying, the internet. Their claim was that anyone streaming video or sound needed to pay up. I mean, honestly, transferring compressed data over a medium!? And of course they didn't go after larger University's that flat out told them they wouldn't pay...
Acacia is one of those companies at the bottom of the barrel. Even worse than SCO, because their whole business is suing over patents, like NTP.
