blair1q writes "CNet reports that Google has lost the lawsuit brought by Bedrock, for infringing on Patent 5,893,120, 'Methods and apparatus for information storage and retrieval using a hashing technique with external chaining and on-the-fly removal of expired data,' and has exposed the Linux kernel, in which the infringing code reportedly appears, to liability for patent-license fees. Red Hat also participated in the suit, arguing that the patent was invalid, but the court decided otherwise."

Combat Wombat brings news that the legal battle between the Australian Commonwealth Scientific and Research Organisation (CSIRO) and a host of major tech corporations has come to end, with a large settlement going to the CSIRO. The fight was over a patent on wireless LAN technology, which already earned the CSIRO a victory in court over Buffalo Technology and a settlement with Hewlett-Packard. The remaining 13 companies, which include Dell, Intel, Microsoft and Nintendo, have now chosen to settle as well. "[The CSIRO] will use the money won from a Wi-Fi technology patent battle to fund further research. ... It is unclear how much money has flowed to the CSIRO, but experts say the technology would be worth billions of dollars if royalties were paid on an ongoing basis."

ClaraBow writes with this excerpt from MacWorld: "A small Indiana company has sued tech heavyweights Microsoft, Apple, and Google, claiming that it holds the patent on a common file preview feature used by browsers and operating systems to show users small snapshots of the files before they are opened. ... Cygnus's owner and president Gregory Swartz developed the technology laid out in the patent while working on IT consulting projects, McAndrews said. The company is looking for 'a reasonable royalty' as well as a court injunction preventing further infringement, he said. ... Cygnus applied for its patent (#7346850) in 2001. It covers a 'System and method for iconic software environment management' and was granted by the US Patent and Trademark Office in March of this year."

BhaKi writes "Remember the Tree-View mode in many file management applications? It's shocking to know that this omnipresent feature was patented by Microsoft back in 1995 (granted in 1997). I'm not very sure about the implications, though. The patent is so general that it can be related to many things from tree-mode to virtual filesystems. Check out claim no. 3 of the patent for the most clear part."

An anonymous reader writes "Congratulations are in order to Ming-Jen Wang of LSI Logic Corporation who, in patent #10260471 managed to invent the linked list. From the abstract, "A computerized list is provided with auxiliary pointers for traversing the list in different sequences. One or more auxiliary pointers enable a fast, sequential traversal of the list with a minimum of computational time. Such lists may be used in any application where lists may be reordered for various purposes." Good-bye doubly linked list. We should also give praise to the extensive patent review performed by Cochran Freund & Young LLP."

An anonymous reader writes "Back in April, LSI was granted patent number 7028023. This is a patent on a stunning new technique in data structures ... the concept that a linked list can in fact have multiple orderings. Of course, this has been used since the beginning of (computer) time in the form of doubly-linked lists. Even if LSI wants to (somehow) claim that the doubly-linked list doesn't count as prior art, maintaining linked lists of graphical objects sorted by both x and y co-ordinates for collision detection has been done since "graphical objects" meant ASCII characters on a green-on-black screen, and has probably been widespread in databases for probably even longer."
