Donald R. Banowit is a director in Sterne Kessler’s Trial & Appellate Practice Group. Don has represented clients from each of the firm’s core technology practices (mechanical, electronics/software and chemical/biotechnology) in patent infringement actions in federal district court and before the U.S. International Trade Commission, and has litigated trademark and copyright disputes. He also has represented both petitioners and patent owners in post-grant proceedings before the U.S. Patent and Trademark Office, including inter partes reviews (IPRs), covered business method patent reviews (CBMs) and reexaminations.

Don has extensive experience managing complex pre-trial issues common to intellectual property litigation, including issues arising from infringement and invalidity contentions, electronic discovery, use of technical and financial experts, and claim construction. He has appeared before magistrates and judges in oral argument of numerous pre-trial motions. He has successfully resolved patent cases prior to trial by way of summary judgment. He has also achieved favorable results for the firm’s clients through settlement and in arbitration and mediation.

At trial, Don’s experience includes obtaining a favorable verdict of non-infringement after a five-day jury trial in the District of Delaware.

Don’s knowledge of patent law, developed through more than fifteen years of practice in the preparation and prosecution of domestic and foreign patent applications, and his education as a “rocket scientist,” provide an invaluable foundation for complex patent litigation. Together with this expertise, he incorporates Patent Forensics and Patent Office Litigation as effective tools to control litigation costs and achieve early settlement or summary judgment disposition.

Don also counsels clients on a wide range of patent, trademark and trade-secret issues, including clearance and due diligence investigations, infringement and validity opinions, non-disclosure, non-compete and joint development agreements, licensing and assignment of intellectual property, intellectual property valuation, patentability opinions and prosecution strategy. Don advises clients on Internet-related trademark and copyright issues, including disputes involving domain names and other aspects of website design and content, and has obtained favorable results in arbitration proceedings under the ICANN Uniform Domain Name Dispute Resolution Policy (UDRP). He represents clients across diverse industries, including consumer products, medical devices, software, agriculture, semiconductor manufacturing, automotive, aerospace, and financial services.

Don is a contributing author of Patent Office Litigation, Second Edition, published in 2017, the book provides a fresh and comprehensive exploration of patent office litigation proceedings, including how the proceedings interact with other aspects of patent procurement and enforcement, while delivering practical analysis and advice. This second edition of Patent Office Litigation is the follow up to the first version of the book that was published in 2012 by Thomson Reuters Westlaw that focused on the contested proceedings that were introduced under the America Invents Act that year. In 2018, The Legal 500 recognized Don as a “Recommended Lawyer” in the U.S. for his part in “ongoing prosecution work for Taiwan Semiconductor Manufacturing, including devising strategies for PTAB proceedings.”

While studying law at Georgetown University, Don was an articles editor on the Georgetown Journal of Legal Ethics. He received his B.S.E. in aerospace engineering, cum laude, from the University of Michigan. Don is a member of Sigma Gamma Tau (the National Aerospace Engineering Honor Society) and the American Institute of Aeronautics and Astronautics (AIAA). Don also is a member of the Steering Committee for The Sedona Conference Working Group 9 on Patent Damages and Remedies and Working Group 10 on Patent Litigation Best Practices.
