Patent Defenses is a way for businesses and individuals to find information about possible defenses to utility patent infringement claims under U.S. law. Although prepared by a law firm, it does not constitute and is not a substitute for competent patent law advice from competent patent professionals. Among other things, the variability of the kinds of inventions to which patent law can apply and the different circumstances in which inventions are made and infringement claims are brought prevent any overview or analysis that would cover any and all specific circumstances. In addition, and even though we seek to update this website on a roughly weekly basis, we necessarily cannot cover all related developments on all issues.
We seek instead to provide information that we hope will be useful as a starting point for thinking about issues relating to defenses against U.S. patent infringement claims.
