Technical Specialist
Unnat's experience includes drafting and prosecuting utility and design patent applications before the U.S. Patent and Trademark Office (USPTO) and in several foreign jurisdictions. He also assists attorneys in performing patentability, due diligence, freedom-to-operate, and invalidity and infringement analyses in numerous technology areas. His prosecution experience covers a wide range of technologies including, biomedical engineering, semiconductor technology, active and passive matrix touch screen displays, medical devices, image sensing and optical signal processing, power electronics, and video gaming technologies.
Unnat has a wide range of technical research experience in the fields of nanotechnology in semiconductors, device fabrication, light emitting diodes, polymer physics, bio-medical devices, printed and flexible electronics, sensors, non-volatile memory design, and thin-film metrology. Prior to joining Finnegan, Unnat was a research scientist in the Opto-Electronics R&D group at Cree Inc., where he designed and developed high efficiency GaN LEDs for a range of applications.
Unnat also worked as a post-doctoral research fellow at King Abdullah University of Science & Technology, Saudi Arabia. His work included designing and fabricating flexible and wearable electronics, particularly developing ferroelectric memory modules on banknotes to prevent counterfeiting. Unnat has authored or coauthored twenty-six technical publications in peer-reviewed scientific journals, which have been cited more than 900 times, and he has presented his research at various international conferences. He is a named inventor on two U.S. patents and a co-inventor on one pending U.S. patent related to his post-doctoral work.
Unnat's doctoral dissertation work focused on design and fabrication of Organic Light Emitting Diodes (OLEDs) on flexible substrates for solid-state lighting applications, a project funded by the U.S. Department of Energy and Army Research Labs. His collaborative research with Pacific Northwest National Lab led to fabrication of record-efficiency blue emitting OLEDs. His work also included optimization of semiconductor thin-film deposition, optical and electrical characterization, and integration of electronic components on flexible substrates. During his early Ph.D. days, Unnat worked extensively on Si-based CMOS design and fabrication, including photolithography, metal deposition, and etch tools.
