Profile bio

About David Cohen

I work with medical device and biotechnology clients to develop their patent portfolio and map the patent landscape that surrounds them. I immerse myself in the client's subject matter, and deliver high-end, understandable, and effective work product. Getting early patent traction with provisional applications can be very important. I work well with outside counsel, if the client has one. I work well with inventors to draw out an invention and its novel features within a patent application that has claims of appropriate breadth.Specialties: patent applications, patent searching, medical devices, biotechnology, cell biology, and physiology.

Listed skills include Patent Preparation, Medical Devices, Cell Biology, Physiology, and 14 others.
