Andrea Porterfield considers understanding a client’s business and goals crucial to developing an effective intellectual property strategy and portfolio. She counsels clients in all areas of intellectual property – from patents, trademarks and copyrights to agreements governing confidentiality, licensing, and distribution to opinion work regarding non-infringement, freedom to operate, invalidity, patentability, and overall industry landscape analyses.

Andrea's patent procurement experience involves preparing and prosecuting domestic and foreign patent applications for clients in diverse technology areas, with particular emphasis on animal health products and processes, food chemistry products and processes, biotechnology, nanotechnology, pharmaceuticals, medical devices, and mechanical engineering. In order to help clients effectively manage their intellectual property portfolios, Andrea routinely counsels clients with respect to short-term and long-term patent procurement strategies. She conducts due diligence analyses of intellectual property portfolios in connection with potential mergers and acquisitions, facilitating identification of technologies for patenting, and evaluating third party intellectual property for potential acquisition and licensing opportunities.
