Professional Experience

Leveraging two decades of intellectual property (IP) counseling experience as both in-house and outside counsel, Dave brings a Chief-IP counsel-type comprehensive and personalized perspective to his law practice.  His business-centered mindset fosters the smooth flow of commerce rather than being an impediment thereto, while at the same time accounting for and minimizing risks and rapidly executing on strategic IP opportunities.  Responsive, transparent, personable, inquisitive, and team-oriented are terms that aptly describe Dave’s seasoned approach.  Intellectual Property comprises a business tool/asset, whether it is a patent, trademark, copyright, trade secret, license, or other bundle of IP-related contractual rights, and Dave is an expert at securing and protecting such rights as well as evaluating and maximizing their value for his clients. 

The core of Dave’s trusted-advisor approach drives from an intense knowledge of the underlying business models of his clients and the various technologies that drive them.  Dave has a wealth of experience securing, leveraging, and asserting IP rights for consumer product destined for retail shelves, technologies or products subject to intense FDA review, or niche industries that helps other businesses work.

Specifically, Dave brings extensive experience advising clients ranging in size from start-ups to multi-national organizations in a variety of technical arenas including medical diagnostics, digital health, additive manufacture and 3-D printing, medical devices, AR/VR software and devices, near-eye displays and imaging/optical technologies, smart garments, compression garments, health and beauty, food prep and catering, athletic equipment, nutraceuticals, machine learning software and devices, nucleic acid sequencing, bioinformatics and data translation, antibody products and targets, immunology-focused technologies, CART-T targets and therapy, consumer devices and services, and information technology.

The core legal work of Dave’s practice includes: Patent prosecution, trademark prosecution, IP licensing/assignment, post-grant patent challenges, trademark oppositions, IP due diligence/opinions and product clearance, litigation (patent, copyright, trademark, trade secret, business), technology-business deal identification and brokering.
