Gilead to Pay Merck $2.5B in HCV Patent Dispute, Stock Falls

Read MoreHide Full Article

Gilead Sciences Inc. (GILD - Free Report) suffered a major setback after a federal jury in the U.S. District Court, District of Delaware ordered the company to pay $2.54 billion in royalties to Merck & Co., Inc. (MRK - Free Report) for a patent infringement lawsuit related to its sofosbuvir-based medicines for the treatment of hepatitis C virus (HCV), including its blockbuster drugs, Sovaldi and Harvoni.

After an almost two-week long trial, the jury came to a decision that Gilead owed 10% royalties on total sales of a staggering $25.4 billion for the two drugs. While Gilead’s shares lost 2.1% in afterhours trading on Dec 15, Merck’s stock gained 1.3%.

Gilead’s year-to-date share price movement shows that the stock has outperformed the Zacks classified Medical – Biomedical and Genetics industry, albeit marginally. The stock has lost 25.3% so far this year, compared to the industry's 25.5% decline. Merck too outdid the Zacks classified Large Cap Pharmaceuticals industry’s performance. It has surged 18.1% so far this year, while the industry lost 6%.

Coming back to the latest news, the decision is reportedly being touted as the largest patent infringement verdict in the history of the U.S. Making matters worse for Gilead, the patent infringement was found to be willful, implying that the judge could increase the damage award by as much as three times the amount set by the jury.

While reports say that Gilead is planning to aggressively appeal to the ruling, the company has asserted that the verdict will not be able to affect sofosbuvir and sofosbuvir-containing drugs sold in the U.S.

We remind investors that Idenix Pharmaceuticals, Inc., which was acquired by Merck in Aug 2014, filed a patent infringement lawsuit against Gilead in Dec 2013, bringing charges against the latter’s method of treating HCV using Sovaldi. In Jan 2012, Gilead had acquired Pharmasset, Inc. in a transaction that added sofosbuvir, a nucleotide analog that acts to inhibit the replication of HCV, to its portfolio.

Gilead gained U.S. approval for sofosbuvir, marketed as Sovaldi in Dec 2013, which was followed by the FDA nod for Harvoni, a combination of sofosbuvir and ledipasvir, in Oct 2014. The lawsuit was meant to determine the first to invent the claimed methods of treating HCV. According to Gilead, Idenix never satisfactorily described what it claimed to have invented and the patent didn’t cover a new idea either.

We note that this was the second time that Gilead and Merck were involved in a patent infringement lawsuit. The first trial was initially resolved in Mar 2016, after a jury in the U.S. District Court, Northern District of California ordered Gilead to pay $200 million to Merck. However, in June, the court ruled in Gilead’s favor and overturned the verdict.

Gilead was also involved in several patent disputes with AbbVie Inc. (ABBV - Free Report) related to its HCV treatment. The companies, however, resolved their disputes and entered into a settlement agreement in Aug 2016.

The latest development has dealt a major blow to Gilead’s stock, especially at a time when the company’s HCV franchise is already reeling under competitive and pricing pressure from Merck’s Zepatier and AbbVie’s Viekira Pak.

Both Gilead and Merck carry a Zacks Rank #3 (Hold).
