Marketing In another round of Merck vs. Merck, Germany-based Merck KGaA notches a win in the U.K.

Back-and-forth between Merck & Co. and Merck KGaA over the Merck name and brand around the word has spanned years. The latest? After years of wrangling, the high court of England recently ruled that Merck & Co. infringed on Merck KGaA’s trademark in that country.

The latest ruling comes two years after a July 2018 hearing. However, the lawsuit goes back even further: The 2018 hearing was an appeal by Merck & Co. of a ruling from 2016 that sided with Germany-based Merck KGaA. The initial complaint was filed by the Germany-based Merck three years before that, in 2013.
