BenedorTSE, LLC filed BenedorTSE, LLC v. Amazon.com Services LLC et al., No. 3:26-cv-01303 (M.D. Tenn.), on September 11, 2026.
Patents and accused products
The complaint asserts U.S. Patents 9,400,979 and 8,463,713, both titled Transactional security over a network. The accused instrumentalities are the Amazon Shopping mobile application and related stored-payment checkout services offered to customers, including in Tennessee.
What the patents cover
U.S. Patents 9,400,979 and 8,463,713 cover ways to harden online purchase transactions - for example, checking a password or related credentials through a graphical interface as part of authorizing a network purchase.
U.S. Patent 9,400,979 covers encrypting a customer identifier string into an encryption stream that moves from customer to merchant in a purchase, with a verification entity that checks the identifiers and returns identity verification and payment authorization to the merchant.
Asserted claims of the '979 patent. At least claims 13 and 19.
Claim 13 of the '979 patent. Paragraph 47 of the complaint maps password validation and device hardware-identifier checks to Amazon's app. The alleged method retrieves a stored user identifier based on at least one of the password or hardware identifier being valid, encrypts the user and hardware identifiers, and sends the encrypted code through a provider for a transaction authorization decision.
Claim 19 covers reading and validating a device hardware identifier, retrieving a stored user-agreement identifier, encrypting those values into a user code, and sending that code to a provider for a transaction authorization decision.
U.S. Patent 8,463,713 covers the same core purchase-authorization pattern: encrypting a customer identifier string for transfer to the merchant, then verifying identifiers and authorizing payment through a verification entity.
Asserted claims of the '713 patent. At least claim 13.
Claim 13 of the '713 patent. Paragraph 58 maps password and hardware-identifier validation to the accused checkout flow, followed by retrieval of a stored user-agreement identifier. The alleged method encrypts that identifier with the hardware identifier into a code valid for only one authorization request and sends it through a provider to a verification entity.
What the lawsuit is about
BenedorTSE maps Amazon's signed-in Shopping app checkout - including stored-payment flows - onto the asserted transactional-security claims. The complaint walks through example customer login and purchase paths as infringement illustrations.
What it means
This is a Middle District of Tennessee suit against Amazon's consumer checkout stack. Watch whether Amazon contests claim construction and whether ordinary password-gated checkout meets the claimed security methods.
What to watch next
Watch for Amazon's answer and any early Section 101 or claim-construction motions. Also watch whether BenedorTSE asserts the same patents against other retailers.
