Katarzyna advises clients on the full range of competition law issues, including complex merger control and antitrust matters.

She represents clients in Phase I and Phase II merger cases before the European Commission and the Polish competition authority. She has broad experience advising on multijurisdictional considerations, as well as remedies in merger cases.

Katarzyna also defends clients in conduct matters and advises on compliance with antitrust rules. Her experience includes handling EU and national investigations and litigation before the EU and national courts.

Her practice focuses on EU and cross- border projects, but she is also adept in domestic Polish matters. Katarzyna has also worked in the Firm's offices in New York and Washington, DC, where her practice focused on international and US antitrust matters.

She advises clients on complex cases of abuse of dominance, involving price-based conduct (rebates), refusal to supply/license and tying/bundling practices. She has also been involved in cartel investigations and in pleading related appeals before the EU Courts.

She has extensive experience in handling cases involving the intersection of IP and competition law, including technology transfer/IP licensing agreements. She received a doctorate (JSD) from Columbia Law School in 2007, where her thesis focused on the intersection between IP and competition law.
