Simon D. Roberts


Twenty-five years of intellectual property law experience with preeminent law firms in both Europe and the United States has made Simon Roberts a skilled and well regarded patent litigator. Simon’s chemistry background and his innate ability to translate complex technical issues into understandable concepts easily understood by judges and juries alike has made Simon an ideal choice for trials and appeals of complex patent litigations in the chemical and pharmaceutical areas. Few patent litigators have Simon’s in depth knowledge and particular expertise in the realm of the Hatch-Waxman litigations. Simon has become a “go to guy” for his clients in the chemical and ethical pharmaceutical industry.

In addition to Simon’s extensive litigation practice before the federal courts, Simon regularly represents clients before the U.S. Patent & Trademark Office (“USPTO”) relating to contested and non-contested proceedings. Simon prepared the first successful supplemental examination request to be filed with the USPTO that included disclosures unrelated to prior art. Simon also has the rare distinction of being permitted to present oral argument before the Patent Reexamination Board of the Chinese Intellectual Property Office in Beijing resulting in the Board upholding the patentability of the patent covering the world’s best-selling HIV medication.

Simon’s particularly varied patent experience and his instinctive ability to understand client needs has made Simon an ideal choice for clients. As Simon recognizes, “the very best client representation involves more than an impeccable understanding of the law, it also involves a better understanding of the client’s needs.”
