The difference between Merck KGaA, Darmstadt, Germany and Merck & Co.

Founded in 1668 in Darmstadt, Merck KGaA, Darmstadt, Germany, is the world's oldest pharmaceutical and chemical company. The success of the export business to the United States led in 1887 to the establishment of an office in New York, which gave rise to our subsidiary Merck & Co. four years later. Owing to World War I, Merck & Co. was expropriated in 1917. The two companies have been separate ever since.
To make it is easier to distinguish between the two companies, clear rules stipulate the rights to the name and the trademark:
  • Merck KGaA, Darmstadt, Germany, – the original – holds the global rights to the name and the trademark "MERCK". The exception is North America, where we are represented by the EMD brand, which stands for “Emanuel Merck Darmstadt”.
  • Merck & Co. of Whitehouse Station, NJ, holds the rights to the name and the trademark "MERCK" in North America. In the rest of the world the company operates as MSD, Merck Sharp & Dohme or MSD Sharp & Dohme.
