Lawsuits in the technology biz certainly aren't uncommon, and it looks like we may have one more significant ruling about to hit just shortly after CSIRO won its own landmark case. The US Supreme Court justices seem to be viewing earlier, lower cases with a hint of skepticism in regard to decisions that have previously worked to safeguard patented products. While the trial at hand concerns two brake manufacturers -- KSR International and rival Teleflex -- the stipulations could be far reaching; the Court of Appeals for the Federal Circuit previously ruled that KSR failed to prove that Teleflex (the accuser) "did not encounter teaching, suggestion, or motivation in developing the product." The generally ambiguous test is a thorn in the side of major technology companies getting slapped around by frivolous lawsuits, and Microsoft, IBM, and Cisco Systems have all made time to "submit briefs supporting KSR's stand." Still, the final decision isn't expected for quite some time, so sue-happy firms still have time to submit their counter-briefs, but folks like Vonage and TomTom (just to name a couple) would obviously (ahem) love a victory here.
