Allen Groenke is a registered patent attorney who brings his extensive history of creative problem solving and technological savvy to Christensen, Fonder, Dardi, and Hebert. Allen is experienced in product development, having been a named inventor on seven U.S. patents during his work as a design engineer. It was through his work in product development that Allen was initially inspired to earn a Juris Doctorate and become a patent attorney. As a patent attorney, he has had the opportunity to advise inventors and executives working in a wide variety of technology areas at three law firms based in Minneapolis.

Allen takes pride in creating patent applications that efficiently communicate why an invention is different and why that difference is notable. He prepares patent application text using a mix of commercially available and custom-written software. Allen believes the most effective method of communicating with clients is through straightforward, visual examples. He enjoys working with engineers and inventors using CAD software to convert digital photographs and CAD models into patent drawings, a skill he acquired through his engineering background.

Prior to Christensen Fonder Dardi, Allen acted as in-house patent practitioner for several venture capital funded startup companies, such as Rotation Medical (acquired by Smith and Nephew) and BridgePoint Medical, a medical device startup that was acquired by Boston Scientific. Allen wrote numerous patent applications for BridgePoint. He also participated in due diligence during the sale of BridgePoint to Boston Scientific in October of 2012.
