This comment explains the development and application of both laches and equitable estoppel defenses in patent litigation. The comment focuses on the recent Court of Appeals for the Federal Circuit decision changing the evidentiary requirements needed to overcome a presumption of laches. In addition to the changes made to laches, the reduction in elements needed to establish equitable estoppel are reviewed. The author concludes that the changes to laches fail to provide additional protection where additional protection is justified, while the reduced elements of estoppel decrease protection for patent owners.
