Daniel Parrish draws on his engineering background to serve clients in patent prosecution, opinion work, and all phases of trial and motion practice. He focuses on patent litigation in federal courts and inter partes review (IPR) proceedings before the Patent Trial and Appeal Board (PTAB). He works with global companies to protect innovations relating to medical devices, automotive and aerospace components, design patents, and computer software. Having spent six years as a biomedical engineer, Daniel understands the complexities and challenges of technology design and implementation, and how these can be leveraged in patent applications and adverse proceedings.

Daniel has been involved in bench trials and mock jury trials; arguing motions and discovery disputes before judges and court-appointed Special Masters; taking and defending depositions; drafting summary judgment and appellate briefs; drafting IPR and reexamination briefs; drafting pleadings on invalidity, noninfringement, and claim construction issues; and managing teams during all aspects of fact discovery. Daniel is also a contributor to the patent treatise, Robert L. Harmon et al., Patents and the Federal Circuit (Bloomberg BNA), and has held the position since 2014. In addition to IP, Daniel is committed to pro bono work. He focuses on issues related to fair housing and wrongful eviction, and has first-chaired multiple bench trials.

Before transitioning into law, Daniel worked at med-tech startups involving neuro-stimulation treatments for obstructive sleep apnea, and ophthalmology treatments for cataracts and glaucoma. He is an inventor on three issued patents (plus one pending patent application) and has authored multiple academic publications. He graduated with honors from the William Mitchell College of Law, holding an editor position in an IP law journal. Daniel holds a Bachelor of Science from the University of Minnesota, double majoring in Biomedical Engineering and Human Physiology.
