    Prior to moving home to Nebraska in 2006, Dave spent a decade in Washington, DC learning how best to assist innovators in protecting and leveraging their ideas. He has worked with entrepreneurs, start-ups and established companies to prepare and prosecute domestic and international patent applications in a wide range of technical fields, including software and web technologies, biotechnology, medical devices, and the chemical and mechanical arts.

    Dave's experience provides him a unique perspective on intellectual property protection and patent practice. His innovation consulting services tightly fit the needs of start-up and early stage organizations interested in building an effective patent portfolio that complements and supports strategic innovation efforts. His approach to intellectual property protection also scales to established entities looking to create and expand their patent efforts.

    Dave's innovation consulting facilitates business entity formation, intellectual property ownership issues, structuring intellectual property assets, leveraging intellectual property for investors and capital formation, and thinking through how to protect, sell or license innovation.

    David has been a huge help with the launch of readySTEADY, a pocket-sized stabilizer for mini camcorders and the iPhone 4. Not only does he know the ins and outs of patent and trademark law, he is able to offer excellent strategic and tactical advice. David is also someone with the highest integrity. I would recommend his services to anyone starting a new business or launching a new product.
