Sandip H. Patel has successfully helped the Firm's clients obtain and enforce patents, defend clients against allegations of patent infringement, and design products and processes to avoid their competitors' patents. Those clients are diverse in size and focus, and have included independent inventors, venture capital investors, specialty chemical companies, universities, and multinational corporations. He has a formal education in chemical engineering, and his day-to-day work deals typically with inventions focusing on chemistry and chemical engineering. But, Mr. Patel's work for the Firm’s clients has spanned the entire spectrum of engineering and sciences. And through that experience, he has proven adept at quickly understanding diverse technologies and devising efficient intellectual property strategies that clients have used to achieve their business goals.

Mr. Patel was selected for inclusion in the 2013 and 2014 Illinois Super Lawyers® lists. Only five percent of the lawyers in the state were selected for this honor.

  • Counseled clients in patent infringement actions in the federal courts involving biotechnology patents (e.g., recombinant growth hormone, recombinant erythropoietin), pharmaceutical chemistry patents (e.g., platinum coordination compounds and methods of treating cancerous tumors), and chemical engineering operations (e.g., air pollution control processes and equipment).
