Thinking Outside the (Utility Patent) Box – Don't Overlook Design Patent Protection in the Life Sciences

August 30, 2019

Design patents are very different from utility patents in that design patents only protect the ornamental features of an invention. In contrast to utility patents, the design is defined in scope by the content of the drawings rather than the words of a set of claims. Further, design patents have a 15 year term, as opposed to 20 years from filing for utility patents.... Read more

An Approach to Pharma Life Cycle Management

August 12, 2019

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...

Four Decisions Designated Informative on 101: Positive Trend for Life Sciences?

July 2, 2019

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.
