An interesting though brief patent interference case concerning flat-panel solar concentrators. The plaintiff (Morgan) had filed a continuation patent application, which is a means of getting additional claims out of a previously-filed specification. The new patent gets the same priority date as the old one, so you don't have to worry about later art (such as that of the competitor whom you want to pay you royalties), but you don't get the usual 20-year patent lifetime. Morgan then came after Banyan.
