Like most things, the innovation environment of 20 years ago was different than today. To help you understand the innovation climate of 2004 for utility patents, and visualize the number of utility patents expiring this month, we offer the following graph. Each dot on the graph corresponds to the number of Patent Applications (x-axis) and Awarded Patents (y-axis) for a USPC Class. Click on the dots in the graph for more detailed information about each USPC Class.
