I do not believe that it would be a patent infringement due to the fact that the patentee's were from
the United States of America.
Design 386955 was granted to Darrel D. Jones & Kathleen E. Jones of Manchester, Kentucky
on Dec. 2, 1997
they applied for a patent on Oct. 18, 1996
it is possible that they shopped around to find someone to make them where the cost would fit their budget, or, someone that would give them a good buyout price.
