WASHINGTON (Reuters) -The U.S. Supreme Court on Friday agreed to hear Amgen Inc (NASDAQ:AMGN)'s bid to revive patents on its cholesterol drug Repatha that were invalidated due to a legal challenge by rivals Regeneron Pharmaceuticals Inc (NASDAQ:REGN) and Sanofi (NASDAQ:SNY) SA.

The justices took up Amgen's appeal of the lower court ruling that threw out the Repatha patents. Amgen and other drugmakers have called the case a test of their ability to earn and defend patents for important drugs.

Amgen first sued Regeneron and Sanofi in 2014 over their rival drug Praluent, which works by a similar mechanism as Repatha. The two monoclonal antibody drugs won U.S. approval weeks apart in 2015.

An Amgen spokesperson said the company was encouraged by the decision and "firmly believes in the validity of its patents."

"Amgen believes that patent protection is essential, not only for Amgen, but also for the entire biotechnology and pharmaceutical industry to make the significant investments required to discover and develop new innovative therapeutics," the spokesperson said.

A spokesperson for Regeneron said it is the company's "longstanding belief" that Amgen's patents are invalid, and it expects a decision from the high court by the end of June 2023.

Representatives for Sanofi did not immediately respond to a request for comment.

Thousand Oaks, California-based Amgen sold more than $1.1 billion worth of Repatha worldwide last year.

The two drugs, which lower "bad" LDL cholesterol by blocking a protein called PCSK9 that prevents its removal from the blood, can reduce the risk of heart attacks and strokes in people with heart disease.

Amgen sued French drugmaker Sanofi and Tarrytown, New York-based partner Regeneron shortly after they sought regulatory approval for Praluent.

Regeneron sold $170 million worth of Praluent in the United States last year, and Sanofi sold over $200 million worth in the rest of the world.

A Delaware judge in 2019 threw out a jury verdict in favor of Amgen after finding the patents invalid. The U.S. Court of Appeals for the Federal Circuit, which focuses on patent law, agreed with the lower court last year, finding that the patents failed to tell an ordinary person how to recreate the antibodies without "undue experimentation."

Amgen told the Supreme Court that the type of patent "genus claims" the Federal Circuit invalidated are common in the pharmaceutical industry, and that the ruling's impact was "devastating, particularly for critical biotech and pharmaceutical innovations."
