Buffalo Technology, long prevented from selling Wi-Fi equipment in the United States, can put its products back on U.S. store shelves now.

In 2005, Australia's Commonwealth Scientific Research and Industrial Organization (CSIRO) decided a patent it owned for some elements of wireless technology could get it some money. CSIRO estimated once that 100 companies around the globe were infringing on their patents.

So CSIRO made an example of Buffalo. In late 2006 it got a summary judgment in its favor. Buffalo (and others) appealed. And that didn't help... As late as September of this year, the U.S. Eastern District Court in Texas upheld the injunction against Buffalo.

The company posted a statement today that says in September the Federal Circuit Court "raised the issue of whether CSIRO's patent is valid and remanded the case back to the district court." The injunction was stayed after that. Buffalo is still looking for a jury to completely invalidate all of CSIRO's claims, but for now, it can get back to the important work of selling you 802.11 routers and network cards, maybe even in time for the holidays.
