Since joining Klarquist in 2006, Mr. Toddy has focused his practice on all aspects of Intellectual Property disputes, from pre-litigation and “alternatives to litigation” such as inter partes reviews, reexaminations, and other post-grant proceedings, through discovery, motion practice and summary judgment, to preparation for trial, as well as related settlement and licensing work. Mr. Toddy has particular experience both prosecuting and litigating patents involving computer software, computer hardware, video game technology and e-commerce applications, as well as medical devices and treatments. He has represented technology clients such as Microsoft, Samsung, SAP, eBay, Adobe, LinkedIn, Netflix, Twitter, Hewlett-Packard, Nokia, and, as well as retail clients such as Office Depot, Staples, J.C. Penney, Burlington Coat Factory, Dillard’s and Costco in intellectual property disputes nationwide, including in California, Delaware, Florida, Idaho, Massachusetts, Nevada, Puerto Rico, Tennessee, Texas and Washington.

Mr. Toddy also has experience in advising clients regarding freedom-to-operate issues, crafting settlement agreements, and intellectual property licensing, and has prepared a number of opinions regarding both non-infringement and invalidity. Finally, Mr. Toddy has extensive experience working on various post-grant proceedings in the USPTO, including first-chair trial and appeal experience in inter partes reviews and reexaminations defending appeals to the Patent Trial and Appeal Board (formerly BPAI). Mr. Toddy’s work on these reexams and appeals often resulted in cancellation of patent claims asserted in litigation for which Klarquist’s clients had obtained a stay pending the outcome of ex parte or inter partes reexams, in many cases avoiding entirely or greatly reducing the cost of having to litigate these claims in district court.


Mr. Toddy’s practice emphasizes both computer- and mechanical-related fields, and in particular the fields of Web commerce and medical devices.
