Dr. Grune is a chemical, mechanical, and materials science engineer, and chemist, possessing expertise related to chemical, mechanical, electrical, and medical products. He has combined this experience by assisting clients in the pursuit of intellectual property protection for the last 20 years. His industrial expertise extends to extrusion and molding of thermoset and thermoplastics, rubbers, textiles, metals, lubricants, surfactants, emulsifiers, fiber optics and associated connecting peripherals, ceramics, liquid gases, and composite materials and systems. He has direct experience in chemical processes, formulation chemistries, polymers and composites, service life prediction, and risk analysis including risk reduction technologies.

He has directed and participated in audit and certification procedures regarding FDA, EPA, USDA, ISO-9000 and ISO-14000/life cycle assessment compliance. He has served as an expert witness in litigation proceedings including electrophotography, medical devices, fuel tanks and fuels, deicing fluids, and wire and cable and associated peripherals.

Dr. Grune has advised, directed, and developed projects including IP protection for downhole oil and gas robotics; medical device; semiconductor microlithography; EMI/RFI shielding; flame retardants and fire prevention; latex paint and road pavement markers; diving and associated sporting goods equipment; food, beverage, water and waste water analysis; personal care formulations and packaging; 3D printing; liquid crystals polymers; gaskets and seals; nano and micro particle technologies; fibers and textiles; polymer chemical resistivity, wire and cable insulations; connectors and splices; environmental effects on durability, and product aging. He has also developed, designed, and scaled-up novel formulations, explosion and flame proof processes/products, and unique material combinations for the packaging and safety protection industries. He has further applied his expertise in developing products and processing for the following industries; solvents, fuels, biofuels, and fuel additives, adhesives, synthetic fibers and fiber physics, accelerated life testing using both material failure and non-destructive analysis, petroleum products, coatings, fibers, films, extruded/molded products, prevention or elimination of toxic and hazardous substances associated with radiation exposure to UVA and UVB, improving telecom systems, road, and transportation markers, electronics, energy transmission and distribution systems, construction designs, fire protection, medical, aviation, automotive, railroad, and a myriad of general consumer products. His skills include development and use of testing tools and methods applied to optical photoconductors (OPC), fuels, biofuels, and fuel additives, personal and sun care protection, food and beverage, drinking water and waste water systems analysis, cryogenic distillation (liquid gases), and downhole oil and gas recovery systems including tertiary oil recovery and fracing. 

Dr. Grune is a named inventor or co-inventor on over 100 US/PCT patents and pending patent applications. He assists clients with most matters related to intellectual property including; full preparation and prosecution of US and PCT applications, technical due diligence and trade secrets, patent infringement, patent validity disputes, valuation, qualification, acquisition integration, IP analysis, and patent litigation support. He has also written and prosecuted over 200 US and PCT patents. 

Prior to joining Exponent, Dr. Grune worked for Fiber Industries, Inc. a division of what is now Hoechst-Celanese, IBM Corporation, ABB Corporation, Mitsubishi Chemical America, and Praxair, serving in R&D, IP, and management roles. 

Dr. Grune serves as an Adjunct Associate Professor in the MEM Program teaching courses involving intellectual asset management (IAM) and patent law, and lectures in green sustainable technologies, thermodynamics, life cycle assessment, and IP valuation for the Pratt School of Engineering at Duke University.
