Detailed Summary
The Swiss competition authority WEKO has formally initiated a preliminary investigation against software company Microsoft. The background is numerous complaints about substantial price increases for Microsoft products on the Swiss market.
Particularly affected is the product Microsoft 365, a cloud-based productivity suite that is widely used by companies, public administrations, and semi-public institutions. According to WEKO's assessment, the documented price increases may indicate impermissible restrictions on competition.
The proceedings are intended to clarify whether the price increases violate the Cartel Act. If the preliminary investigation reveals evidence of violations, a formal in-depth investigation can be initiated. WEKO can draw on the expertise of the Price Surveillance authority.
