A federal judge in Texas granted summary judgement in favour of the CSIRO and demanded Buffalo pay it a royalty rate to be decided at an upcoming court date.
The CSIRO filed the test case against Buffalo in February last year claiming it has infringed its wireless LAN patent, granted in 1996. CSIRO chief executive Dr Geoff Garrett said the judgment was important as it "supported CSIRO's position comprehensively".
"We are obviously very pleased," Garrett said, "however, it is only a brick in the wall and CSIRO still has a long way to go." Garrett said the market for WLAN (wireless LAN) products is large and growing. Many manufacturers are using CSIRO's technology without permission or any licence fee.
CSIRO has a number of other ongoing patent-infringement cases.
