Biography
Dan Callaway has represented numerous companies in all aspects of patent litigation, including patent and portfolio analysis, complex discovery, depositions, expert and witness preparation, pleading and motion practice, Markman proceedings, PTAB trials, courtroom argument and trial work.
Prior to attending law school, Dan obtained a master’s degree in electrical engineering, and spent four years working as an engineer at a startup semiconductor company. He designed hardware, wrote and debugged source code, and drew great satisfaction from bringing new chips from the lab into full production. He is an inveterate builder and tinkerer, and fascinated by how things work. As a result of his hands-on engineering experience, Dan is particularly effective at working on technical subject matters and with clients who are engineers. He speaks their language, and appreciates the nuance of their work.
Dan’s cases have included disputes over patents related to integrated circuit design, storage and networking, power delivery, computer processor and memory design, operating system and application software, and consumer products. He has also worked on cases involving electromechanical devices, security systems, and virus protection. His clients have included semiconductor companies, solar energy companies, computer hardware and software companies, a manufacturer of storage and networking products, a manufacturer of home and automotive electronics, online travel websites, and a non-profit research institute.
Dan has extensive experience with inter partes review proceedings before the Patent Trial and Appeal Board. Regardless of the forum, as a practitioner Dan’s process involves the careful, thorough examination of the intellectual property in question, and in-depth work with engineers, technologists and inventors to collect the evidence that informs how cases are ultimately resolved. In a legal field where evidence can obscure more than it reveals, Dan excels at locating the needle in the evidentiary haystack that supports his clients’ positions, and allows him to be an effective advocate.
Dan is the inventor of U.S. Patent No. 6,794,568, a device for detecting musical gestures using collimated light.
