Take a little closer look at 102(b)
(b) the invention was patented or described in a printed publication in this or a foreign country or in public use or on sale in this country, more than one year prior to the date of the application for patent in the United States
The statute clearly says more than one year before an application is filed in the United States
. Only a priority relationship to certain PCT filings or another U.S. application allows for an earlier U.S. filing date
. The foreign priority will still knock out 102(a/e) references with a date in the 4/21/2006-4/20/2007 range.

III. EFFECT OF RIGHT OF PRIORITY
The right to rely on the foreign filing extends to overcoming the effects of intervening references or uses, but there are certain restrictions. For example, the 1 year bar of 35 U.S.C. 102(b) dates from the U.S. filing date and not from the foreign filing date
; thus if an invention was described in a printed publication, or was in public use in this country, in November 1981, a foreign application filed in January 1982, and a U.S. application filed in December 1982, granting a patent on the U.S. application is barred by the printed publication or public use occurring more than one year prior to its actual filing in the United States.
