J. Elwood Lee Co. v. B. F. Goodrich Co.

Tbe suit is brought upon patent No. 390,177, dated September 25, 1888, and granted to J. Elwood Lee, for an improved catheter. The bill is demurred to for want of patentable novelty in the claimed invention. But the improvement is in a surgical instrument. On its face it appears so far new and useful that professional or expert information, beyond common knowledge, is necessary to show that it is not. Demurrer overruled. Defendant to answer over by January rule day.
