Experience
Antitrust/Competition
At Hausfeld, Sofie is part of the legal team which:
- Filed an opt-out collective action with the CAT on behalf of an estimated 19.5 million eligible UK users of smartphones and tablets running on Google’s Android operating system relating to excessive and unlawful charges on purchase in the Google Play App Store. The claim alleges that Google unfairly restricts consumers from accessing potential competition from other app distributors, by requiring smartphone manufacturers to pre-install a bundle of Google’s proprietary apps and services including the Google Play Store as well as imposing other contractual and technical restrictions.
- Filed a representative collective action with the CAT on behalf of some 19.6 million eligible UK iPhone and iPad users relating to excessive and unlawful charges by the Apple App Store. The claim alleges that Apple’s conduct violates section 18 of the UK Competition Act 1998 and Article 102 of the Treaty on the Functioning of the European Union.
- Filed a representative collective action with the CAT on behalf of the Consumers’ Association (known as Which?) against Qualcomm on behalf of a class of around 29 million UK consumers alleging that Qualcomm abuses its dominance in the markets for smartphone chipsets and standard essential patents, the result of which is that Qualcomm is able to overcharge smartphone manufacturers like Apple and Samsung for its technology. Damages are estimated to be over £480 million.
- Assisted in pursuing damages claims relating to auto-parts cartels for several leading automotive manufacturers.
