Andrew Y. Piatnicia Founder & Principal Tel: 408-641-1747

I am a litigator and registered patent attorney with twenty-five years of combined experience litigating patents (federal court and ITC), inter partes reviews & reexamination, analysis and development of patent portfolios, patent prosecution, and licensing.  I have also advised on trade secrets.

Formerly a partner at the international law firm Howrey,  I have worked in a range of technologies, whether hardware, software, or mechanical e.g., cell phones, chip design, computer networks, computer controlled machines, disk drives, graphical interfaces, image sensors, LEDs, memory chips, microprocessors, microwave and antenna technology, position sensors, power systems, software defined storage, wafer manufacturing, and wireless communications.

Before practicing law, I was a senior design engineer at Westinghouse in microwave technology.  I am also a former registered Professional Engineer.

My firm handles matters of various sizes and complexities.  On particular matters with client consent, I associate with legal personnel including independent and experienced lawyers.  In addition, I will support other firms, for example, in cases of specialized need.

I founded Piatnicia Legal to represent companies of all sizes, including start-ups and international companies.
