We have a deep understanding
of the law.

Our legal knowledge runs deep.

In fact, we wrote the book on Patent Defenses.

Klarquist launched and maintains Patent Defenses, a unique, mobile-friendly legal research tool for businesses and individuals to find information about possible defenses to patent infringement claims under U.S. law.

Search a term or keyword

Patent Defense’s search feature can be used to find detailed information on specific subject matters, such as “double patenting,” “exhaustion,” or even case names.

Browse topics of interest

Patent Defenses is organized into easy-to-navigate sections. Simply select a category to learn more about subjects, such as “novelty” and “obviousness.”

Explore recent case highlights

Short summaries of selected substantive patent law Federal Circuit decisions can be found here, and these decisions are updated frequently.
