`The Law of Teaching Away
`
`• The law states that disclosed examples and preferred
`embodiments do not constitute a teaching away. In re Susi,
`440 F.2d 442 (CCPA 1971).
`
`•
`
`In order for a teaching away to exist, the prior art must
`criticize, discredit, or otherwise indicate the undesirability of a
`particular solution. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir.
`2004).
