Muna 1987, Michael Houghton, Qui-Lim Choo, naGeorge Kuo paChiron Corporation, vachishanda naDaniel W.

Chikumbiro chepatent chinokwikwidzana neCDC chakadonhedzwa muna 1990 pashure pokunge Chiron abhadhara $1.9 miriyoni kuCDC uye $337,500 kuna Bradley. Muna 1994, Bradley akamhan'arira Chiron, achitsvaka kuita kuti patent isashande, kuti iye azvibatanidze semuvambi, uye kugamuchira kukuvadzwa uye mari yemvumo. Akasiya nyaya yacho muna 1998 pashure pokunge akundwa mudare rokukwirira.  Mubvunzo: Mugore ripi muedzo wokuongorora wakashandiswa pakupedzisira mukutevedzera?
