Amazon, IBM settle patent lawsuit will pay an undisclosed sum to Big Blue, ending disagreements over e-commerce patents that allegedly began in 2002.

Meanwhile, the U.S. patent system itself is experiencing growing pains as Congress continues to explore the possibility of updating it to better serve the needs of the 21st-century business world.
