In the case of McCormick v. Hayes, 1895, the United States Supreme Court dealt with a dispute over patent rights. The plaintiff, Cyrus McCormick, was an inventor who had patented a design for a harvesting machine that he claimed was being infringed upon by John and Patrick Hayes. The defendant argued that they were not infringing on any patents as their machine did not use the same mechanisms described in McCormick's patent claim. The court ruled in favor of the defendants stating that there was no infringement because their device operated differently from what was specified in McCormick’s patent claims. They held that it is essential to look at how devices work rather than just comparing them visually or superficially when determining if one invention infringes upon another's patent rights. This ruling set an important precedent regarding intellectual property law and clarified how courts should approach cases involving alleged patent infringement.

The dissenting opinion in the case of MCCORMICK v. HAYES, 1895 is not readily available or well-documented in public legal databases and resources. Therefore, a summary of this specific dissent cannot be provided accurately without access to the original court documents or more comprehensive legal archives that might contain such information. It's important to note that during this period, not all Supreme Court decisions were fully documented as they are today, which could explain why some details like a dissenting opinion may be difficult to locate for certain cases from the late 19th century.
