A more thorough explanation:

CUSTOMS AND PATENT APPEALS, COURT OF

The Court of Customs and Patent Appeals was an Article III court established in 1929 to handle appeals in cases related to customs and patents. It was replaced by the U.S. Court of Appeals for the Federal Circuit in 1982.

One example of a case that would have been heard by the Court of Customs and Patent Appeals is a dispute over a patent for a new invention. Another example is a disagreement over the amount of customs duties owed on imported goods.

For instance, if a company claimed that another company was infringing on their patent for a new type of smartphone, the Court of Customs and Patent Appeals would have been responsible for hearing the appeal if the case had been brought before it. Similarly, if a business imported goods from another country and there was a dispute over the amount of customs duties owed, the Court of Customs and Patent Appeals would have been the court to hear the appeal.

These examples illustrate how the Court of Customs and Patent Appeals was responsible for hearing appeals in cases related to customs and patents. It was an important court for resolving disputes in these areas of law.
