Well, all mine (all are group patents):
1 6,374,064 Xerographic development system, method for determining when the developer material supply should be replenished
2 6,321,045 Xerographic development system, a method for predicting changes in the ratio of toner to carrier
3 6,285,840 Print quality control for a xerographic printer having an AC development field
4 6,285,837 System for determining development gap width in a xerographic development system using an AC field
5 6,266,494 High-altitude compensation for a xerographic development system
were done by the patent lawyers at Xerox. I know it took over 1 1/2 years for them to come in, and I'm pretty sure there was alot of research into existing patents to justify the cost of apllying before they were sent to the patent office.
