WHAT'S NEEDED: REQUEST FOR INFORMATION

This patent application was filed on June 8, 2001 but claims continuation from a patent application filed June 12, 1998, resulting in an earliest date of invention of June 12, 1997. While it is possible that the invention did not occur until after June 12, 1997, finding relevant prior art that published before that date assures it application. Publications can include any form of printed or electronic publication that discusses one or more elements of the claim of the patent.
