Charlotte Stewart-Sloan focuses her practice on US and foreign patent prosecution and opinion work in areas related to chemistry and materials science. Charlotte supports clients of all sizes (including midsize companies, start-ups, and universities) in technology spaces including 3D printing, batteries, coatings, filter media, LEDs, medical devices, sensors, diagnostics, laboratory devices, microfluidics, oil and gas recovery, and water purification. Her experience includes drafting and prosecuting patent applications, patentability studies, freedom-to-operate analyses, and invalidity opinions.

Charlotte finds learning about her clients’ technologies and business strategy to be one of the most rewarding parts of her practice. She is committed to understanding what is important to her clients and aligning her strategic recommendations with what best helps them achieve their IP and business goals.

Prior to joining Wolf Greenfield, Charlotte performed graduate research at MIT, where she worked under the supervision of Professors Ned Thomas and Bradley Olsen. For her master’s work, she collaborated with international scientists to establish an experimental phase diagram for the technologically-relevant poly(styrene)-poly(dimethylsiloxane) diblock polymer. Her doctoral research focused on engineering new responsive materials for biocompatible and energy applications and on understanding the novel polymer physics required to control the nanoscale structure and properties of these complex systems. Charlotte has also authored successful proposals for synchrotron X-ray time at the National Synchrotron Light Source, the Advanced Photon Source, and the Stanford Synchrotron Radiation Lightsource.

Charlotte has experience as a teaching assistant in the Departments of Materials Science and Engineering and Chemical Engineering at MIT, where she assisted in the development of a new course “Structure of Soft Matter" targeted toward graduate students performing research on structural characterization of soft material.
