Daniel H. Broaddus works with clients on patent preparation and prosecution for technologies involving analog and integrated circuits, as well as cloud computing and the Internet of Things. He has worked with leading developers and manufacturers of mobile phones, network infrastructure backbones, wireless technologies, and consumer electronics. From amplifiers and antennas to signal processing and video compression, Daniel helps protect innovations that drive success in the marketplace.

With a doctorate in Applied & Engineering Physics from Cornell, Daniel can directly relate to inventors. He speaks their language, understands the core technology, and asks inventors precise and informed questions that ultimately translate their work into effective patent applications. Similarly, Daniel’s strong grasp of technical details allows him to work with patent examiners to identify paths to allowability that meet his clients’ goals.

Daniel’s practice is always forward-looking. Writing an effective patent involves keeping in mind where technology is likely to go in the future, and how it will evolve. Daniel’s educational background and technical experience allow him to anticipate the competitive landscape, and help his clients protect their valuable innovations for as long as possible.
