Written Descriptions: How Much is Enough? Court Will Revisit Ariad Case to Clarify the Amount of Disclosure Necessary in Patents
February 1, 2010
Foley Partner Courtenay Brinckerhoff authored an article titled, “Written Descriptions: How Much is Enough? Court Will Revisit Ariad Case to Clarify the Amount of Disclosure Necessary in Patents” in the Genetic Engineering & Biotechnology News. Brinckerhoff discusses the Federal Circuit’s decision to rehear Ariad Pharmaceuticals, Inc. v. Eli Lilly & Co. en banc to resolve an intra-court split over whether 35 USC § 112 imposes a written-description requirement that is separate from the enablement requirement. She reviews how the outcome of the case could have significant impact on biotechnology patents, which are often vulnerable to written-description challenges.
