What is coherent light? Don't rely on attorney argument.

From Ex parte Jennings

That is, a multi-wavelength laser emits light at multiple wavelengths and the beams emitted from the laser. As discussed in our Decision, we agree with the Examiner that light emitted from a laser, regardless of the wavelength, is coherent light. Decision 4.

The Appellants contend that the Appellants have provided evidence that light emitted from lasers at different wavelengths is not coherent light. Request 2-3. However, the Appellants contention fails to cite to any specific evidence to support such an assertion. As such, the Appellants’ argument is tantamount to nothing more than attorney arguments and conclusory statements.


Attorney arguments and conclusory statements that are
unsupported by factual evidence are entitled to little probative value. See In
re Geisler, 116 F.3d 1465, 1470 (Fed. Cir. 1997); see also In re De
Blauwe, 736 F.2d 699, 705 (Fed. Cir. 1984).
