Toyota lawyers arrived at the U.S. Supreme Court today and were denied an appeal to overturn a ruling originally upheld by a federal appeals court in Washington last year. The case involved a technology patent held by a company named Paice LLC, which contended that Toyota used the same microprocessor developed by the McLean, Virginia-based company on its hybrid vehicles that inputs torque information for both the gasoline-powered engine and the electric motor. The $4.3 million dollar award against Toyota will stand, and Toyota is required to pay royalties to the firm to the tune of $25 for every Prius, Highlander Hybrid and Lexus RX400h sold. Ouch. Sometimes the price of success is steep.
