In a recent decision, the Austrian Supreme Court clarified certain aspects of the legitimacy of addressing warning letters to employees. In the case, an interim injunction was granted to the defendant against the claimant's "sales manager Austria". As the claimant had no place of business in Austria, but sold infringing coffee machines via its Austrian distributors, the defendant felt impelled to warn the employees of the claimant who were actively participating in the distribution of the infringing coffee machines in Austria that an accomplice or assistant is also liable for patent infringement.
