  • Obtaining complete defense verdict in retrial of a multi-billion dollar cybersecurity patent litigation involving nearly a dozen patents;
  • 100% success rate as lead counsel for a seasoned IPR petitioner in challenging the validity of patent claims at the U.S. Patent Trial and Appeal Board; and
  • Winning case-critical claim construction and summary judgment rulings in popular patent venues such as the District of Delaware and the Eastern District of Texas.

He is a United States lawyer and patent attorney with an electrical engineering background.  Mr. Baird’s practice focuses on patent disputes, with an emphasis on U.S. district court litigation and inter partes reviews (IPRs) before the Patent Trial and Appeal Board (PTAB) of the United States Patent and Trademark Office (USPTO).  He is experienced in patent proceedings in the United States and abroad, including Europe, from pre-filing stages through trial and appeal.  He provides technical and legal analysis, conducts diligence and fact development, works with experts and witnesses, takes and defends deposition and live testimony, prepares and argues motions, and manages the day to day efforts of trial teams.  He is a member of the firm’s U.S. Patent Trial and Appeal Board practice group, which has led to the firm’s consistent ranking as the number one most successful law firm in the country for petitioners in IPRs.  See Unified Patents’ institutional success index (2018-20224).  He has been lead counsel in multiple IPR proceedings before the PTAB, from drafting the initial petitions through arguing in final Trial Hearings, and regularly provides direction and training for the PTAB practice group.

He has experience in international intellectual property matters, including both prosecution and international disputes.  He advises clients in international IP strategy and has collaborated with foreign associates on a variety of international IP matters, including those related to patent litigation in Germany.  Before joining Duane Morris in April of 2005, he clerked for a boutique intellectual property firm in Sydney, Australia.  He has also lived in Germany, where he became proficient in conversational German.

Mr. Baird also has experience in prosecuting patent and trademark applications before the USPTO, as well as advising on international strategies and filings.  He is a registered patent attorney in the U.S., focusing in the electrical and mechanical arts.  He also has experience drafting, analyzing and negotiating intellectual property licenses, including patent, trademark and software licenses.

He represents clients in matters covering a diverse range of technologies, including data communications and networking (including WLAN/WiFi, 4G/LTE, WPAN, MoCA, OFDM, VoIP, SIP, RTP protocols, techniques and infrastructure), network security (including intrusion detection and protection systems and protocols, as well as telemetry based systems), video imaging and conferencing, data center infrastructure and virtualization, mobility (including Mobile IP and other tunneling techniques), optical fiber communications (including precoding, laser optics, modulation technologies, amplifiers, add/drop multiplexing and switching, coherent transmission and detection, demodulation and equalization), thin films and related deposition techniques, semiconductor fabrication, packaging and circuitry, digital advertising, medical devices, lighting and other consumer electronics.
