Patent dispute hangs over kringle 5

Judah Folkman1

  1. Children's Hospital, 300 Longwood Ave , Boston, Massachusetts 02115, USA

Sir — In June you published a News brief relating to a suit brought by Abbott Laboratories against Children's Hospital in Boston and against me and two of my younger associates1. The suit asserted rights to a patent assigned to Children's Hospital on an endothelial and angiogenesis inhibitor called kringle 5 which was discovered in the hospital's laboratories.
