DARE V. BOTLSTOH. 493 �tions have been repeatedly announced, and in one case as to an interlocutory decree. In the latter case the thought was that after an interlocutory decree as to a product the in- fringer should not be permitted to put on the market an inferior product to the detriment of the plaintiff, whereby not only a competition should occur in the market, but the infe- rior product disparage the true product. That case can have no adequate reference to this ; for it may be that the defend- ants' machines are, as to praotical utility, superior to those manufactured by the plaintiff, still the patentee is entitled to what the law grants, and if any difficulties occur, as Bug- gested, they are to be corrected by le^slation, and not by judicial decision. �The decision of the court, therefore^ is that the motion for rehearing is overruled, and the motion to suspend the inter- locutory decree for a perpetuai injunction is also overruled. ���DabE V.
