David Kohn primarily handles patent preparation, prosecution and evaluation. His expertise covers a wide range of technical fields, including magnetic resonance imaging, optoelectronic circuits, semiconductor fabrication, implantable electronic medical devices, metamaterial resonators, power factor correction equipment, interferometry techniques, and wireless telecommunication networks. He quickly builds fluency in the subject technology, and uses that fluency to carry meaningful and in‑depth conversations with inventors and technical experts.
Translating Technology into Value
David excels at breaking down complicated ideas into not‑so‑complicated terms. While eager to delve into the mathematical and code‑based minutia that make up an invention, he is equally watchful to consider how that minutia translates into a real‑world, marketable solution. From conducting patentability searches and performing freedom to operate studies, to developing strong infringement or validity positions in the course of litigation, David always brings a value‑oriented angle to the task at hand.
Patents have many uses, they are not one‑size‑fits‑all. Understanding a client's needs — and more importantly, keeping a client involved in the patenting process — is key to delivering the most useful end result. David keeps a keen eye on each of his clients' specific needs, and delivers high‑value work with those needs in mind.
The Big Picture
David has a wealth of experience prosecuting patent applications not only in the United States, but also in several foreign jurisdictions, including Europe, China, Japan, Korea, Canada and Australia. Using his understanding of foreign patent regulations, both procedural and substantive, he routinely works with clients to develop comprehensive global strategies.
David also keeps himself regularly involved in the firm's litigation activities, notably in patent validity challenges and Markman hearings. Having both patent prosecution and litigation experience makes him a well rounded attorney with a big picture sense of a patent's worth. David's involvement in the litigation setting, where tactics frequently center on the weak points or vulnerabilities of a patent, puts him in an excellent position to recognize those vulnerabilities, and to prevent them ahead of time, during prosecution.
