As a registered US patent attorney and partner of the firm, Chris represents generic pharmaceutical, biotechnology and medical device companies in intellectual property litigation in federal district courts throughout the US, as well as inter parte review (IPR) proceedings before the US Patent Trial and Appeal Board (PTAB). Chris has particular expertise in Hatch-Waxman and medical device cases, and has handled intellectual property cases covering diverse areas of technology including recombinant proteins, fluorescent and halogen lighting, epidermal scanners, and semiconductors.

Pharmaceutical and Biotechnology Experience

Chris counsels and represents pharmaceutical and biotechnology clients from the earliest stages of product selection and pre-litigation activities (including patent avoidance and invalidation strategies) through the entirety of filing the Paragraph IV notice letter, fact and expert discovery, claim construction, trial, and appeal. Chris has litigated disputes concerning pharmaceutical compounds, drug and finished dose formulation (including oral, topical, injectable, and subcutaneous dosage forms), crystallization and polymorphs, dosing schedules, drug indications and uses, adverse events, pharmacokinetics/pharmacodynamics, organic and process chemistry, and methods of treatment.

Chris has fought to bring generic equivalents of many well-known pharmaceutical products to market across a number of therapeutic classes, including COPAXONE (multiple sclerosis); PRISTIQ (antidepressant); EFFEXOR and EFFEXOR XR (antidepressant); AZILECT (Parkinson’s disease); AXIRON (testosterone therapy); NIASPAN (extended-release niacin); ONGLYZA and KOMBIGLYZE (diabetes); ARICEPT (Alzheimer's disease); ABILIFY (antipsychotic); AVINZA (morphine sulfate); and LUNESTA (sedative).

Chris has represented global medical device companies in connection with products in the upper extremities (shoulder, elbow, wrist and hand), lower extremities (foot and ankle including bone plates and screws), and biologics markets (xenograft), as well as large joint orthopedic devices for the hip and knee (acetabular cup systems, modular hip replacement prostheses, artificial knee implant technology). Chris is also registered to practice before the U.S. Patent and Trademark Office and has prosecuted patent and trademark applications relating to cardiac defibrillators, stents, catheters and other transvascular devices, as well as recombinant proteins and hormone detection kits.
