Tensions Between Nonobviousness and Written Description in U.S. Patent Law

October 27, 2020 | Duane Morris LLP | Webinar

Duane Morris is hosting the webinar, "Tensions Between Nonobviousness and Written Description in U.S. Patent Law," on  Tuesday, October 27, 2020, from 12:00 p.m. to 1:00 p.m. Eastern.

About the Program

United States patent law establishes requirements that inventors and applicants must satisfy to obtain a patent, which include utility, recitation of patent eligible subject matter, novelty, nonobviousness, an adequate written description, enablement and the best mode of practicing the invention. Biogen International GmbH v. Mylan Pharmaceuticals, Inc. presents an example of tensions between the nonobviousness and written description requirements.

This webinar will discuss the background on this case, including claims at issue and Biogen’s prosecution strategy, and the best practices and lessons learned from the court decision.

We invite you to read the Duane Morris Alert, “Playing Your Cards Right: Arguments Against Obviousness Can Be Detrimental for Satisfying the Written Description Requirement,” which was republished in the Intellectual Property & Technology Law Journal.
