Rakoczy Molino Mazzochi Siwik

Rakoczy Molino Mazzochi Siwik LLP (RMMS) is a Chicago-based IP litigation boutique specializing in pharmaceutical patent and regulatory counseling. The firm maintains a single office in Chicago, Illinois, but serves clients nationwide and globally. Established in 2004, RMMS has grown to comprise over 30 attorneys and technical advisors, uniquely focusing on the life sciences sector. Chambers USA and The Legal 500 consistently recognize RMMS for its intellectual property and life sciences litigation capabilities.

The firm's patent litigation practice is deeply specialized in the biopharmaceutical sector, particularly in Hatch-Waxman and Biologics Price Competition and Innovation Act (BPCIA) matters. RMMS is highly regarded for its representation of generic pharmaceutical manufacturers in complex Abbreviated New Drug Application (ANDA) litigation, frequently defending against brand-name drug owners. While their primary focus is life sciences, RMMS also leverages its patent litigation expertise for clients in other industries.

RMMS has a strong track record of success in high-stakes patent disputes. Notable engagements include representing Mylan Pharmaceuticals Inc. in patent litigation initiated by Regeneron Pharmaceuticals, Inc., and defending Fresenius Kabi USA, LLC against Haemonetics Corporation. Historically, the firm secured a non-infringement win for Aveva Drug Delivery Systems, Inc. in litigation concerning a lidocaine topical system, and obtained an invalidity judgment against Eli Lilly's Prozac® product, leading to 180 days of generic marketing exclusivity for their client. The firm also maintains a practice in post-grant proceedings, with experience in PTAB matters, as evidenced by their representation in Unified Patents LLC v. Wilus Institute of Standards and Technology Inc.

Key partners driving the firm's patent litigation practice include William A. Rakoczy, a co-managing partner recognized by Chambers as a Band 1 attorney in Intellectual Property and Life Sciences: IP/Patent Litigation, noted for his expertise in Hatch-Waxman and BPCIA trials.
