About Heidi

Heidi served as the firm's managing partner from 2016 to 2019.  Her practice focuses on patent prosecution and counseling, including validity, infringement and due diligence opinions. She has represented clients in patent matters involving a wide range of technologies primarily in the chemical industry, including adhesives, paint, coatings, polymeric films, packaging, composites, lubricants, sealants, electrochemistry, semiconductors, pharmaceuticals, and food science. Heidi’s practice also includes trademark prosecution and counseling. She has transactional experience, including drafting and negotiating patent and trademark license agreements.

Prior to joining Renner Otto in 2000, Heidi served as in-house patent and trademark counsel for The Sherwin-Williams Company. She began her career as a research engineer for B.P. America (The Standard Oil Co.); and later joined the Patent and Licensing Department of B.P. America as an attorney. The corporate experience is of significant benefit to Heidi’s current practice. She acquired a detailed understanding of in-house intellectual property operations and a familiarity with the issues that often arise in corporations, allowing her to assist her corporate clients with those issues.
