PERFECT TAILBOARDS v. BILTWELL AUTO BODY CO.

December 12, 1938

PERFECT TAILBOARDS, PATENTED,
v.
BILTWELL AUTO BODY CO., Inc.



The opinion of the court was delivered by: CAMPBELL

CAMPBELL, District Judge.

This is a suit in Equity for the alleged infringement of Patent No. 1,695,609 issued to Frank Richter, for "Tailboard and Tailboard Mounting for Truck and the Like," granted December 18th, 1928, on an application filed June 27th, 1927.

This suit is based on claims 1, 2 and 4.

 Title to the patent in suit is in the plaintiff, and its right to maintain the action was stipulated at the trial.

 Defendant interposed an answer which was in effect a general denial, but, by amendment made on the trial, it included an allegation of prior use by the defendant.

 No prior art patents or publications were offered in evidence, and no testimony was given as to any prior use, except that of the defendant.

 3. "A tail-board for trucks and the like forming a connection which will be strong and rigid as well as being close and which will withstand extremely rough usage and have great endurance qualities."

 4. "An extremely simple, hinged connection preferably formed of metal parts."

 5. "A hinge connection between a tail-board and the end of the truck in which a round pipe or rod may be utilized as a pivot and in which part of the knuckles of the hinge will be formed by providing notches in a metallic edge piece, preferably of U-shaped configuration, extending to opposite surfaces of one of the parts to be connected thereby, such as the edge of the truck and cooperating hinge-knuckles will also consist of looped straps projecting ...
