In the 1903 case of Swarts v. Hammer, the United States Supreme Court dealt with a dispute over patent rights. The plaintiff, Swarts, had been granted a patent for an invention related to gas burners and subsequently sold exclusive rights to manufacture and sell products using this technology to another party. However, he continued manufacturing these items himself as well. The defendant, Hammer purchased some of these products from Swarts directly and was sued by the party who bought the exclusive rights from Swarts on grounds of infringing their patent right. The court ruled in favor of Hammer stating that when an inventor sells his patented product without any restrictions or conditions attached regarding its use or resale; it is no longer within monopoly protection under patent law - also known as "patent exhaustion" doctrine or "first sale" doctrine. This means that once a patented item has been legally sold by either inventor or licensee (with consent), they cannot control what happens next with that particular item including reselling it further down line because they have already received their reward through initial sale transaction.

In the dissenting opinion for Swarts v. Hammer, it was argued that the majority's decision to uphold a tax on inheritances violated constitutional principles of uniformity and equality in taxation. The dissenting justices contended that the law unfairly imposed different rates of taxation based on arbitrary factors such as the relationship between the deceased and their heirs or beneficiaries. They believed this created an unjust system where some individuals were taxed more heavily than others without any rational basis for such discrimination. Furthermore, they disagreed with the majority's interpretation of "property" under inheritance laws, arguing that money received from an estate should not be considered property until it has been legally transferred to its new owner through probate proceedings.
