Opinion

UNITED STATES DISTRICT COURT DISTRICT OF DELAWARE No. 1:25-cv-00180 Ameranth, Inc., Plaintiff, V. DoorDash, Inc., Defendant.

OPINION AND ORDER Plaintiff brought this action alleging that defendant infringes U.S. Patent No. 11,276,130 (’130 Patent). Doc. 14 at 40. Defendant moved to dismiss the complaint under Federal Rule of Civil Pro- cedure 12(b)(6). Doc. 54. Defendant argues that the 130 Patent claims patent-ineligible subject matter under 35 U.S.C. § 101. Doc. 55 at 7. The court agrees. I. Procedural arguments Plaintiff argues that the court should deny defendant’s motion for “sandbagging” by asserting arguments for the first time in the reply brief and not applying plaintiff’s proposed claim construc- tion at the pleading stage. Doc. 56 at 8-15. Those arguments lack merit. Plaintiff argues that defendant ignored the plaintiff’s factual allegations and proposed claim constructions, failed to properly apply those constructions, and disputed the constructions which waived defendant’s arguments applying plaintiff’s constructions in the reply brief. Doc. 56 at 8-11. Defendant’s motion argued that plaintiffs proposed constructions should not be accepted because the constructions contradict the ’130 Patent’s claims and specifi- cation. Doc. 55 at 17-21. “[A]t the motion to dismiss stage, factual allegations in the complaint which contradict the specification or the claims need not be credited as true under the Rule 12(b)(6) analysis.” IPA Techs., Inc. vy. Amazon.com, Inc., 352 F. Supp. 3d 335, 343 (D. Del. 2019) (citing Aatrix Software, Inc. v. Green Shades

-l-

Software, Inc., 882 F.3d 1121, 1125 (Fed. Cir. 2018)). Thus, these arguments were proper. Moreover, defendant adds that “should the [c]ourt adopt [plaintiff’s] proposed constructions for purposes of this motion,” the court should still dismiss because the claimed components are abstract and do not add an inventive concept. Doc. 55 at 19. De- fendant argued for a construction based on the intrinsic record and alternatively argued that the claims are still ineligible under plaintiff’s proposed constructions. Defendant was free to respond to plaintiff’s counter-arguments on both points in its reply brief. Further, defendant—and this court—are not bound to apply plaintiff’s proposed construction. Aatrix, 882 F.3d at 1125. Plain- tiff misstates the law when asserting otherwise. Compare Doc. 56 at 11 (“Applying [plaintiff’s] proposed constructions . . . as this court must do . . . .”) with Aatrix, 882 F.3d at 1125 (“we have held that either the court must proceed by adopting the non-moving party’s constructions, or the court must resolve the disputes to whatever extent is needed to conduct the § 101 analysis, which may well be less than a full, formal claim construction.” (citation omitted)). II. U.S. Patent No. 11,276,130 Plaintiff is the assignee and owner of the ’130 Patent. Doc. 14 at 6. The ’130 Patent “relates to an information management and synchronous communications system and method for generation of computerized menus for restaurants and other applications with specialized display and synchronous communications re- quirements.” ’130 Patent col. 1 ll. 17–21. The “principal object of the [’130 Patent] is to provide an improved information manage- ment and synchronous communications system and method which facilitates user-friendly and efficient generation of comput- erized menus for restaurants and other applications.” Id. col. 2 ll. 61–65. In other words, the ’130 Patent discloses an information management and synchronous communications system—a sys- tem that allows for real-time data exchange between two or more parties simultaneously—for use in the food and hospitality ser- vices industry. The ’130 patent teaches computerizing the traditional pen- and-paper ordering common to “restaurant/hotel/casino food/drink” services. Id. col. 3 ll. 43–61. Computerization pro- vides a more efficient mechanism for ordering than the traditional method of a customer verbally ordering food and the hospitality service employee manually writing it down on paper. Id. col. 1 ll. 31–39, col. 3 ll. 43–51. This advancement may be accomplished using “typical hardware elements in the form of a computer work- station, operating system and application software elements” that configure the hardware—including a central processing unit, mi- croprocessor, RAM, ROM, hard drive storage, modem, display screen, keyboard, mouse, and removable storage devices (e.g., floppy drive or a CD ROM drive)—to achieve computerized or- dering. Id. col.6 l. 57–col. 7 l. 9. In summary, the ’130 Patent teaches an efficient hospitality ordering system using computer elements known in the art. There are three claims in the ’130 Patent, one independent and two dependent, that cover: 1. An intelligent web server computer with multi- modes of contact, multi-communications protocols, multi- user and parallel operational capabilities for use in com- pleting remotely initiated hospitality food/drink delivery or pick up ordering tasks comprising; at least one said web server computer with web server software; at least one hospitality food/drink ordering software application for delivery or pick up orders integrated with the at least one said web server computer; an advanced master database comprising data and pa- rameters of the at least one hospitality food/drink ordering software application integrated with the at least one said web server computer and with a usa- ble menu file structure dictated prior to task execution and is accessible via its own database API and with one or more predefined formats stored within it and which intelligently learns, updates and stores multiple communication modes of con- tact and related operational parameters for hospi- tality entities and for remote hospitality users along with their prior attributes or preferences, if any and then intelligently applies them; Middleware/Framework Communications Control Software (MFCCS) which enables via its central- ized system layer architecture the at least one said web server computer to communicate with two or more remote wireless handheld computers and for multiple modes of contact, multiple communica- tions protocol functionality, integrated with the master database and with the at least one hospital- ity food/drink ordering software application; at least one external software API, which enables the full integration of the at least one hospitality food/drink ordering software application and the MFCCS with one or more non hospitality applica- tions via the internet; the external software API integrating with and leverag- ing the advanced master database to enable the im- porting of food/drink menus including required and non-required modifiers which are then auto- matically reflected throughout the master menu tree file structure, improving efficiency while elim- inating the necessity of continually querying or checking every tree branch in the master menu tree file structure when responding to remote user re- quested tasks and/or other inputs; wherein the at least one said web server computer is integrated with the MFCCS, the hospitality food/drink ordering software and is programmed with instructions enabled to intelligently choose and apply multiple and different modes of contact and/or different communications protocols, if ap- plicable with the said hospitality entities and/or said remote users associated with the user re- quested hospitality food/drink delivery or pick up ordering application tasks and is enabled to support the completion of those tasks. 2.
