For businesses selling products through Amazon, a patent infringement notice can quickly become a significant commercial problem. Amazon's Patent Evaluation Express (APEX) program allows U.S. utility patent owners, or their registered agents, to seek a neutral evaluation of an alleged infringement claim involving products sold on Amazon. An APEX notice can put an established product listing at risk, potentially disrupting sales, affecting marketplace visibility, and creating complications for inventory already manufactured or held in fulfillment centers. Sellers that have not considered these risks before receiving a notice may find themselves making important business and legal decisions under significant time pressure.

There has been an increasing number of lawsuits threatened and filed in the last year against ecommerce marketers and other online companies based on their use of analytical and other “non essential” marketing-related cookies. These actions typically allege violations of various federal and state privacy statutes—most notably the California Invasion of Privacy Act (“CIPA”), including California Penal Code §§ 631(a), 632, 632.7, and 638.51—and challenge widely used online advertising and tracking practices such as the usage of cookies, pixels or the alleged interceptions of communications. It is important to note that there have been no definitive legal rulings on these claims, and this is an ever-changing area of the law, which is being increasingly exploited by plaintiff’s attorneys.
