Post v. T. C. Richards Hardware Co.

This is a demurrer to a bill in equity for an injunction against the alleged infringement of a design patent. The bill alleges that the inventor invented “a new and original design for a curtain and loop,” and that letters patent therefor, of a specified number and date, were granted and delivered to the inventor. The usual averments are made in regard to the execution of the letters patent. No other description of the invention is given, and no reference is made to the patent for a further description. The ground of the demurrer is that the hill “does not set out the nature, character, or description of the pretended patented design referred to in said bill, nor the letters patent alleged to have been obtained therefor, nor make any profert of the same.”

It is necessary that a hill in equity for an injunction against the infringement of letters patent for an invention should contain such a *906description of the invention, as patented, as will apprise the court of its nature and character, and the particulars in which the improvement consists. This may be done by a full and accurate description in the pleader’s own language, care being taken not to depart from the legal effect of the language of the patent, or by employing the language of the specification, or by a reference to and proferí of the patent.- The last-named course is the usual and most convenient one. The bare averment that the design was “a design for a curtain and loop” is not sufficient.

The demurrer is allowed, with leave to amend.
