This Supreme Court case involved Henry O'Reilly, Eugene L. Whitman, and W. F. B. Hastings (appellants) versus Samuel F. B. Morse, Alfred Vail, and Francis O Smith (respondents). The appellants had filed a bill in the Circuit Court of the United States for the Southern District of New York to obtain an injunction against respondents from using their invention related to telegraphy without permission or compensation from appellants who claimed they were entitled to it due to prior inventions by them that formed part of this new invention by respondents which was patented under their name only as inventors without any reference made to appellants’ prior inventions used in its construction or operation . The circuit court dismissed the bill on grounds that there was no infringement upon patent rights held by appellant but rather a combination with other elements not covered under patents already issued nor applied for at time when respondent's patent was granted thus making it impossible for appellant's claim of infringement valid since none existed between two parties .The Supreme Court affirmed decision rendered by lower court stating that even though some parts may have been similar ,the combination as whole did not infringe upon existing patents held by either party thus dismissing appeal brought forth before them

In the case of Henry O'Reilly, Eugene L. Whitman, and W. F. B. Hastings v Samuel F. B Morse, Alfred Vail, and Francis O Smith (1853), the dissenting opinion argued that Congress had not intended to grant a patent for an invention which was already in use by others prior to its application date; rather they believed it should be limited only to inventions which were novel or new at the time of their application for a patent. The dissenters further argued that if Congress had meant to include existing inventions as well as those newly invented then they would have included language in their statutes explicitly stating this fact instead of leaving it open-ended with no clear definition on what constituted novelty or originality when applying for a patent from the US Patent Office. They concluded by saying that allowing patents on existing technologies would lead to monopolies over certain industries and stifle innovation within them due to lack of competition among inventors who could otherwise improve upon these same technologies without fear of infringement lawsuits from those holding such patents granted under questionable circumstances like this one before them now being considered by the court today
