The doctrine of equivalents is an equitable exception to the basic concept that the patent claims define the limit of claim protection. It is intended to prevent one from making an insubstantial change to a claimed invention to avoid infringement which is defined by the function-way-result test. The doctrine is limited by the prior art, dedication to the public, and prosecution history estoppel.... Read more

Every innovative pharma company faces the same challenge, how to delay the patent cliff. The existence of the "skinny viii" (21 U.S.C. § 355(j)(2)(A)(viii)) makes developing additional FDA approved indications unattractive from an LCM viewpoint. Such additional indications may allow for market expansion during the life of the patents protecting the original indication but offer no protection once those patents have expired. With a skinny viii the generic seeks approval only for indication with the earliest patent expiration. Formulation patents often provide scant protection because of the possibility of design arounds and being more easily challenged for invalidity since often the original patents are available as prior art...

In January, 2019, the USPTO issued new guidance about what constitutes an abstract idea that is ineligible for protection under Section 101. Among other things, the guidance emphasized that claims otherwise reciting a judicial exception (i.e., not patentable), would be permitted if they were directed to some type of practical application. See our previous post for more details.... Read more
