Mika Ito has deep and specific experience in patent prosecutions of U.S. and foreign patent applications for emerging technologies including semiconductor technology (circuitry and fabrication), online entertainment (including use of artificial intelligence, augmented/virtual reality, audio and video signal processing, and distributed ledger systems), interactive user interface applications (including use of augmented/virtual reality, speech technology, and tactile inputs), automotive electronics (GPS and telematics), and health and medical applications (including non-invasive diagnosis and treatment techniques, remote monitoring systems), among others. Mika also analyzes patent portfolios for competitive coverage and litigation risk.

Mika also advises clients on open-source licensing matters. Using her experience as a software engineer, she provides legal training about open-source licenses to software engineers.

Earlier in her career, she was an intellectual property engineer with Alpine Electronics of America, Inc.; a patent scientist; a software engineer at Sony Corp.; and a speech linguist at David Geffen School of Medicine at UCLA.
