Marcus counsels clients on a wide range of intellectual property issues, including patent portfolio development and management, intellectual property litigation, intellectual property licensing, intellectual property acquisition, and intellectual property due diligence. His clients span a number of different industries, including energy, mining, life sciences, health care, medical devices, defense, aerospace, and university research and development.

While Marcus has particular experience with energy, mining, and medical device technologies, his patent prosecution and counseling experience covers a wide range of technology areas, including materials science, chemistry, biotechnology, photonics, mechanical and electro-mechanical devices, and industrial designs for various different technologies. Some examples of specific technologies he has worked with include polycrystalline diamond cutting elements and bearings; drill bits and bearing apparatuses used in oil and gas exploration drilling systems; tunnel boring machines for mining; medical devices, including stents, catheters, bone implants, neuromodulation devices, cardiovascular devices, implantable and wearable ophthalmic corrective devices, drug delivery devices, urinary devices, renal devices, and nickel-titanium-based superelastic and shape memory alloys for stents and other implantable medical devices; chemical separation devices, including chromatography systems and stationary phases; combustion control systems; food science and technology, including food compositions, food processing, and food packaging; composite materials; and lasers, fiber optics, photodetectors, and other photonic devices.

In the patent field, Marcus helps his clients analyze the risks associated with introducing new products, including analyzing infringement and validity issues, and preparing related opinions.  When a client needs assistance dealing with an intellectual property infringement or enforcement issue at the district court or the Patent Trial and Appeal Board (PTAB), Marcus works with the client and Dorsey intellectual property trial attorneys to provide the most cost-effective strategy  to realize the client's goals.

Before practicing law, Marcus gained practical engineering experience as a materials engineer at a large aerospace corporation that designs solid-fuel rocket motors.
