Derrick W. Toddy


Portland Office



Derrick’s practice encompasses advising and assisting clients during all phases of the patent life cycle, from prosecution strategy and freedom to operate analyses, to litigation and “alternatives to litigation” such as USPTO post-grant proceedings, to patent acquisition, licensing, and settlement.

Leveraging his skill as both a registered patent attorney and experienced patent litigator, Derrick has prosecuted and litigated patents in mechanical and software-related fields. Representative clients span multiple industries, including technology companies Microsoft, SAP, and Amazon, sports equipment manufacturer Taylor Made Golf, and medical device manufacturers Dexcom and Edwards Lifesciences. Derrick has represented clients in intellectual property disputes in district courts nationwide, from California to Massachusetts to Puerto Rico, and points in between, and on appeal to the Federal Circuit.

Derrick also has extensive experience in preparing and defending inter partes reviews, reexaminations, and other USPTO post-grant proceedings, routinely arguing before the Patent Trials and Appeal Board (PTAB).

Derrick joined Klarquist as a lateral associate in 2006, and became partner in 2019.
