Princeton Biochemicals, Inc. v. Beckman Coulter, Inc.

Princeton asserted their patent rights on capillary electrophoresis technology against Beckman. Beckman persuaded the lower court to set aside the jury verdict because those skilled in the art at the time of the invention understood coiling of capillary tubes, the relevant prior art was analogous and the nature of the problem itself suggested the solution. The CAFC affirmed.
