c37:No. 2195
LOWELL, District Judge (concurring). I agree with the conclusion of the majority of the court. The assignor of a patent may not assert its invalidity. All that the patentees did was to adopt for use in a printer’s table an alining bar, which was old in the analogous art of drawing boards. Bergner United States patent No. 195,915, October 9, 1877. This, in my opinion, did not involve-invention.
