David Hanson is an experienced litigator who believes persuasive storytelling is the key to winning trials. As a shareholder and former co-chair of Reinhart’s Litigation Practice, he translates complexity into clarity to ensure lay juries and judges fully understand his client’s position. Dave handles patent, trademark, copyright and trade secret cases as well as Taft Hartley and ERISA litigation, including withdrawal liability matters. According to Chambers USA, one of the nation’s leading attorney peer review services, “He is very intelligent and a great litigator."
His nationwide practice spans many industries, including engineering, mechanical and electrical technology fields. Dave has represented clients involved in materials handling, mining, cloning and gene sequencing, construction, manufacturing and various consumer product industries. He partners with clients to understand how technical and intellectual assets drive their business and their position in the competitive landscape.
Dave is skilled presenter and confident speaker with first-chair presence. His trial strategies are pragmatic, straightforward and consider long-term costs and benefits beyond the immediate dispute. He’s also creative in resolving conflicts short of trial when it makes good business sense. Dave continually hones his litigation and teaching skills while investing in others:
As an Adjunct Professor at Marquette University Law School since 1997, Dave developed the IP Litigation Workshop, an upper-level course covering all facets of a patent case from investigation to trial.
As a guest lecturer at Northwestern University Law School, Dave participates in mock trial exercises for Masters of Science in Law students as part of the course, “Communicating Scientific Information: Technical Professionals and Expert Witnesses.”

Speaking often, combining substantive legal topics with his interests in design and visual learning to create memorable presentations. Recent talks include “Trends in Patent Royalty Damages” and “Intellectual Property and the Professional Engineering Firm.”
As an AAA arbitrator, Dave was retained by two national firms to preside over a dispute over the scope of an inventorship contract.
As an expert witness, Dave was retained by a large peer firm to give opinion testimony on the reasonableness of attorney fees in a patent infringement case.
