Todd focuses his practice on intellectual property litigation and intellectual property counseling with a bent on worldwide IP. He counsels companies on the procurement of IP assets and management of worldwide IP portfolios with a particular focus on protecting IP assets in China. He provides Chinese, German, Japanese, British and Italian companies general counseling on doing business in the U.S.

Todd’s first-chair patent trial experience includes securing a jury verdict of non-infringement for a snow plow manufacturer, obtaining a non-infringement judgment for a maker of house arrest bracelets and obtaining a series of preliminary injunctions for a manufacturer of construction products. 

He was co-lead on a trial team that won more than $39 million for infringement of his client’s semiconductor testing equipment patent – the largest verdict in 2011 for the State of Arizona.

He has been first-chair in Section 337 Investigations before the International Trade Commission. His ITC experience includes two significant victories in 2022. In one of these investigations, the ITC ordered his client, who was accused of patent infringement, dismissed from an investigation mid-way through the ITC hearing due to the patent holder’s expert admitting non-infringement during cross-examination.

Todd also has experience with reexamination proceedings, inter partes reviews, post grant reviews and derivation actions in the U.S. Patent Office. On behalf of a large medical device manufacturer, he recently invalidated in IPRs all claims over a family of six patents own by the client’s major competitor.

Todd has developed and managed global patent enforcement programs for a variety of clients. These programs include obtaining preliminary injunctions in the United States while managing worldwide counsel seeking to enforce related patent rights throughout Europe and Asia. He is global patent counsel for a large Chinese manufacturer of wireless radios where his client is involved in patent litigation on four continents against their largest competitor. 

As part of his global IP experience, he assists clients with protecting business interests and inventions in China. He has managed the IP for several Chinese R&D centers and is well-versed in many aspects of Chinese IP Law, including procurement and enforcement of Chinese patents, utility models and trademarks.

Todd also has managed Chinese invalidation proceedings and is experienced with the nuances of IP licensing in China.

Todd has been tasked by several clients with the strategic management of patent portfolios, including coordinating a network of international patent counsel for worldwide patent procurement and protection of medical devices, consumer products, food packaging and construction material inventions.

He provides clients with right-to-market, patentability and non-infringement/invalidity opinions.

Todd is licensed to practice before the U.S. Patent and Trademark Office.

Since 2016, Todd has been recognized for his work in Intellectual Property by Chambers USA, most recently ranked Band 2 in Ohio.

He is deeply experienced in IP and brings a real wealth of knowledge." Another client stated, "Todd stands out in his ability to provide practical advice from a multinational IP perspective because of his strong, unique background in patent litigation and international patent prosecution.
