SFA Systems v. Amazon: SFA Permitted To Amend Infringement Contentions Where Amendment Would Streamline Discovery And Prejudice To Amazon Would Be Minimal
SFA Systems ("SFA") filed a patent infringement action against Amazon and twenty-six other defendants in 2011. SFA subsequently timely served its infringement contentions pursuant to the local rules in the Eastern District of Texas. After receiving discovery from Amazon, SFA requested that Amazon supplement its discovery responses to produce documents relating to the Kindle Fire and the Amazon Mobile application. Amazon declined to do so on the basis that the Kindle Fire and the Amazon Mobile app were not accused in the infringement contentions. After several attempts to meet and confer, SFA sought to amend its infringement contentions.
As explained by the district court, the local Patent Rule 3-6 sets forth the procedures for amending infringement contentions. This rule provides that infringement contentions.

The district court then noted that "[t]he Parties agree that SFA's original Infringement Contentions accused the product recommendations' back-end system that powers the Amazon.com website. Plaintiff's proposed amended Infringement Contentions accuse the same product-recommendation system, while specifying that the accused system may be accessed by different devices or channels."
As the district court explained, the rules are not meant to provide a forum for litigating substantive issues. "The preparation and supplementation of infringement contentions is a matter of pleading and merely notifies a defendant of the asserted theories of infringement in order to provide adequate notice and streamline discovery. Davis-Lynch, Inc. v. Weatherford Int'l, Inc., No. 6:07-cv-559, 2009 WL 81874, *3 *(E.D. Tex. 2009). While infringement contention must be reasonably precise and detailed to provide a defendant with adequate notice of the plaintiff's theories of infringement, they need not meet...
