Everett v. Thatcher
Opinion of the Court
When this case was before us in March last, we inspected the model of the invention and intimated an opinion adverse to complainant. But his counsel are now insisting that we ought not to base our judgment in this case upon a personal inspection of the model, because they say it is not one of the things of which the court can take judicial notice. The proposition is certainly correct. We cannot take judicial notice of the model, nor have we assumed to do so. The patent is prima facie evidence of its own validity, and if nothing more appeared in the case, we would declare it valid and protect it against infringement But it is only prima facie good and not conclusive. The responsibility of adjudicating it valid or invalid is with the court and we must do this upon legitimate evidence legally adduced in the case. The model is competent evidence, and has been exhibited as such by the complainant.
If the court is not authorized to inspect and pass judgment upon it, why is it introduced? It is a prevalent, if not universal, practice for the courts in litigation of this character to examine such models. And why may they not do so? Witnesses may be called to examine models of inventions as experts and give their opinions of their merits. And may
There is, however, other testimony on file showing the state of the art, at the time which supports the view we have taken. But as we are entirely satisfied, from the personal inspection we have made, that the pretended invention is not patentable,- we are content to rest our judgment on this evidence alone, and do not, therefore, desire to hear the evidence read. But in order to preserve the rights of defendants, we will consider it as having been read and as a part of the files of the case.
It has been urged that the patent involved has been adjudged valid by the circuit court of the United States for the western district of Pennsylvania, and this adjudication is relied on as authority here. The judgment of that court, if based upon a bona fide contest, and after careful consideration, would be entitled to great respect. But, as we are advised, that judgment was rendered on a pro confesso without answer or hearing, and upon the complainant’s statement of his case. Such decrees are rendered upon mere motion, without investigation, and are not such adjudications as to preclude full inquiry by us.
A decree will be entered dismissing complainant’s bill with costs.
