Appeal No. 2006-1149 Application No. 10/296,406 the knowledge of one of ordinary skill in the art, or, in some cases, from the nature of the problem to be solved." Brown & Williamson Tobacco Corp. v. Philip Morris Inc., 229 F.3d 1120, 1124-25, 56 USPQ2d 1456, 1459 (Fed. Cir. 2000). An obviousness determination requires not only the existence of a motivation to combine elements from a different prior art reference, but also that a skilled artisan would have perceived a reasonable expectation of success in making the combination. Medchem S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006). While the definition of "reasonable expectation" is somewhat vague, it does not require a certainty of success.

Ex parte Erlich, 3 USPQ2d 1011 (Bd. Pat. App. & Inter. 1986). We will sustain the examiner's rejection of claim 18 for the reasons argued by the examiner and also because we find that one of ordinary skill would readily discern from the nature of the problem to be solved that reversing the connection orientation of male and female electrical connectors would be required in certain applications. If a person of ordinary skill in the art is presented with a female connector on an automotive wiring harness, they will instantly recognize that a male connector is required to connect with the female connector and vice-versa. It is unclear how the design choice of substituting a male connector for a female connector would be materially impacted by the angle of the -13-Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 NextLast modified: November 3, 2007
