The IPS Irsch AG is the largest patent law firm in the canton Thurgau as well as one of the largest in all of eastern Switzerland. The success story of the company began in 2005 with the founding of the sole proprietorship Intellectual Property Services. In 2013 this was transformed into a GmbH of the same name with its seat in Frauenfeld. This was the beginning of a decidedly dynamic development, which quickly turned the law firm into a renowned internationally active player. In preparation for the establishing of the IPS Irsch Group a transformation into a stock corporation followed in 2021. The service capability and the quality of the services rendered have played a significant part in the corporate success of the patent law firm from Frauenfeld.
