Toyota has, once again, failed to shake the long-looming hybrid patent infringement case brought forth by Paice LLC. In this latest development, a U.S. International Trade Commission judge dismissed Toyota's bid to end the lawsuit, continuing a trend. Toyota has long argued that the suit filed by Paice is invalid and should be dismissed, but the courts have routinely ruled otherwise. An earlier court ruling forced Toyota to pay royalties for several of its vehicles which encroach upon hybrid patents filed by Paice. Toyota currently pays royalties to Paice for every Prius, Highlander Hybrid and Lexus RX400h model sold. And though Paice originally wanted Toyota to halt sales of the listed models, it now appears that Paice is satisfied with the royalty agreement.

The drama doesn't end there. Toyota is now back in the courts arguing against the royalty amounts paid per vehicle, while Paice has filed yet another complaint against Toyota which alleges that the automaker has also infringed upon patents with technology found in the third-generation Prius, Hybrid Camry, Lexus RX450h and HS250h. This fiasco has been ongoing for years now with no end in sight.
