With almost 30 years of experience practicing law in both Europe and the United States, there is little Simon Roberts hasn't seen. Simon focuses on patent litigation in the life sciences and biotechnology sectors where he leverages his background in chemistry to translate complex technical issues into relatable terms.

Known as a "go-to guy" for his clients, Simon is a top choice when it comes to patent disputes. He has deep experience and knowledge in the realm of Hatch-Waxman litigations as well as other pharma-related patent maters. Simon is proud of his record of successful outcomes in virtually every of the high-stakes litigation matters he has handled. In addition to his extensive litigation practice before the federal courts, Simon represents clients before the United States Patent and Trademark Office (USPTO) in contested proceedings including IPRs and PGRs. Simon orchestrated the first winning supplemental examination request to be filed with the USPTO that included disclosures unrelated to prior art leading to the significant strengthening of a patent portfolio protecting one of the world's most successful branded pharmaceutical products.

Simon also has the rare distinction of being permitted to present oral argument before the Patent Reexamination Board (PRB) of China's Intellectual Property Office (SIPO) in Beijing, resulting in the PRB upholding the patentability of the patent covering an active ingredient in the world's best-selling HIV medications.
