Roque El-Hayek is involved in the preparation and prosecution of patent applications focusing in the areas of biotechnology, cellular and molecular biology, drug delivery, medical therapeutics, and pharmaceuticals.

Prior to joining the firm, Roque served as a Senior Research Associate with Boston Biomedical Research Institute where he studied the molecular mechanisms involved in the regulation of intracellular calcium in skeletal and cardiac muscle.

During his postdoctoral fellowship at the University of Wisconsin Medical School Departments of Physiology, Anesthesiology and Pediatrics, Roque studied the regulation of purified skeletal and cardiac ryanodine receptors and dihydropyridine receptors by endogenous intracellular modulators as well as drugs. He also studied the effects of recombinant growth hormone therapy on growth and renal function in an experimental model of compromised kidney function.

Roque has authored and co-authored over 20 articles in journals including Biochemistry, Journal of Biological Chemistry, Biophysical Journal, and American Journal of Physiology.

Client testimonial:
"Case management is very important here, and Roque is phenomenal. He is very approachable, accessible and concerned about spending the client’s money. With the other firms we used to work with, you felt like the meter was always running, and that cheapens the relationship. With him, I never felt like he was talking just to get to the next seven-minute billing increment."
Client testimonial:
"The fact that Roque is an MD is fantastic. He understands academic institutions and he understands that our clients are very smart people and he keeps the internal client happy."
Client testimonial:
"Roque is great and the most well-prepared person."
Client testimonial:
"Roque gives some talks, and those are beneficial. It shows that they are engaging their clients. We learn a lot when Roque comes over."
  • Assisted leading academic medical institution in securing patent protection for licensed diagnostic test now widely used and expected to be used on millions of patients and is the basis of a new therapeutic indication.
