Mary Sue Henifin are the co-authored a chapter in the recently released Aspatore Books publication, Inside the Minds: Patent Enforcement Best Practices. Henifin is a shareholder in the Princeton office of Buchanan Ingersoll & Rooney PC and a member of the firm's Commercial Litigation Section.

The chapter, titled "Build, Maintain, and Enforce Strategic Market Exclusivity," defines patent law and the four main areas of concern with reference to assertion of rights: claim construction (proper scope of the subject matter of the claim), validity (the patent claim meets the statutory requirements for patentability under the current judicial interpretation of Title 35 of the United States Code), enforceability (the patent claim was obtained without intentional misrepresentation or omission of facts material to the patentability), and infringement (the accused subject matter meets all the limitations of the asserted claim either literally or under the doctrine of equivalents) including contributory and/or inducing infringement.

The chapter also outlines major patent-related issues that clients might face.
