MEMORANDUM OPINION AND ORDER I. INTRODUCTION Before the court is another antitrust case brought against Defendant Google LLC that rests in part on this court’s determination that Google is a monopolist in the general search services market. Plaintiff Sensory, Inc. is a software company that develops and licenses software associated with wake words and voice assistants. Wake words are verbal commands that activate a voice-controlled device. Think “Hey Siri” or “Hey Google.” Sensory alleges that Google’s exclusionary distribution agreements with Android device manufacturers violate Sections 1 and 2 of the Sherman Act and parallel provisions of the D.C. Code in nearly a dozen different product markets. They include not only the markets for wake word and voice assistant technologies, but also those for general search services, general search text advertising, access points to general search services, and speech-to-text voice recognition software, among many others. Google moves to dismiss, arguing that Sensory has failed either to plead antitrust standing or to adequately define these product markets.

For the reasons that follow, Google’s Motion to Dismiss, ECF No. 20, is granted in part and denied in part. Only those claims relating to the four alleged product markets for wake word, voice assistant, and voice recognition technologies used to support Android smartphones and tablets may proceed to discovery. Sensory’s Motion for Leave to File a Surreply in Opposition to Defendant Google LLC’s Motion to Dismiss, ECF No. 23, is denied. II. BACKGROUND Sensory’s factual allegations include numerous references to the proceedings in United States v. Google LLC (Google Search), 747 F. Supp. 3d 1 (D.D.C. 2024), including this court’s liability determination, trial exhibits and testimony, and the parties’ filings. See, e.g., Pl.’s Renewed Mot. for Leave to File First Am. Compl. Partially Under Seal, ECF No. 19, First Am. Compl., ECF No. 19-1 [hereinafter Am. Compl.], ¶¶ 9–10, 38–62, 70–71, 80–100, 176– 180, 189. The court therefore will consider the relevant factual findings made in that case. Otherwise, the court will focus on those allegations unique to Sensory’s claims.

A. Wake Words and Voice Assistants Wake words are words or phrases used to “initiate verbal communication” with a device.

Id. ¶ 15. On smartphones and tablets, a wake word is “commonly used to access voice-based ‘assistants,’ which are used to conduct internet searches and return information to the user.” Id. ¶ 181. A voice assistant “is a virtual assistant that can respond to voice commands to perform various tasks.” United States v. Google LLC (Google Search Summ. J.), 687 F. Supp. 3d 48, 86 (D.D.C. 2023) (internal quotation marks omitted).

Each voice assistant is typically associated with a unique wake word. Am. Compl. ¶ 182.

For example, “Hey Siri” is the unique wake word activating Siri, the voice assistant on Apple devices, and “Hey Google” or “OK Google” are the unique wake words for Google Assistant, the

voice assistant on certain Android devices. Id. ¶¶ 15, 63. But wake words also are used to initiate verbal communication with devices other than smartphones and tablets. Id. ¶¶ 20, 30.

As discussed, voice assistants can be “used to conduct internet searches and return information to the user.” Id. ¶ 181. When a user makes a spoken search query to the voice assistant, the voice assistant will transcribe the spoken query and then enter the transcribed text into a search engine. Id. ¶ 65. So “[f]rom the perspective of the search engine, the system runs the same whether the search query is typed or spoken.” Id. Voice assistants can therefore be considered search access points, which are “the places at which a consumer may enter a general search query.” Id. ¶ 213; see also id. ¶¶ 63, 66, 197.

B. Sensory’s Products and Technologies Sensory is a Silicon Valley–based software company that describes itself as an “innovator in the development of wake words and other voice recognition technology, including custom voice assistants, voice control, and sound ID technologies.” Id. ¶ 1. It claims to be the “first technology company to solve certain specific problems in wake words and their deployment with voice assistants,” including “(1) avoiding false acceptance (waking up when no one intended the device to wake up); (2) avoiding false rejection when the consumer says the right word and the device doesn’t respond; (3) addressing privacy concerns requiring the wake word technology to run locally on device so spoken data is not constantly streamed to a cloud; and (4) keeping power consumption to a minimum to reduce battery drain for devices that are not plugged in.” Id. ¶ 16. It also claims to have “solved complicated technological problems related to a concept called ‘concurrency,’” which “allows more than one voice assistant to run simultaneously on a device and to be activated by distinct wake words.” Id. ¶ 17.

Sensory develops and licenses three products related to wake words: TrulyHandsfree, TrulyNatural, and TrulySecure. Id. ¶ 24. TrulyHandsfree “covers wake words and commands using keyword spotting.” Id. Sensory alleges that, “[f]or certain customers, Sensory’s TrulyHandsfree Product on its own acts [as] a voice assistant, because it can both activate a device when it detects that the appropriate wake word has been spoken, and it can follow up device activation with an action, such as ‘call,’ ‘take a photo[,]’ ‘take a video’ or a similar command.” Id. ¶ 25. TrulyNatural “supports larger vocabularies using grammars, speech to text, acoustic models and language models,” id. ¶ 24, and can “enhance[] the voice assistant capabilities of a device,” id. ¶ 26. And TrulySecure “permits speaker verification, Face ID, and sound ID.” Id. ¶ 24.

Sensory’s “wake word technology” has been licensed and used by several major original equipment manufacturers (“OEMs”) of smartphones, tablets, and other hardware, including Microsoft, Apple, Samsung, Motorola, Lenovo, and Google. Id. ¶¶ 19–20, 23, 27. Sensory alleges that its wake word technology was once used on many smartphones and tablets running on the Android operating system, id. ¶¶ 23, 28–29, and that its “wake words have been the front end of many search engines[1] including Google, Cortana, Siri, and Alexa,” id. ¶ 21. Other leading consumer electronics manufacturers, such as Amazon, Hasbro, Plantronics, GoPro, Tencent, and Garmin, also have integrated Sensory’s technologies into their products. Id. ¶ 20.

C. Google’s Wake Words and Voice Assistants In 2012, Google endeavored to incorporate wake words and spoken command capabilities into a new product, Google Glass. Id. ¶ 30. But because Google did not at that time “have its own

1 The court presumes reference to “search engines” in paragraph 21 is an error, as Cortana, Siri, and Alexa are voice assistant products, not search engines. Google, of course, is a search engine, but given its inclusion alongside other voice assistants, Plaintiff likely here means Google Assistant. If Sensory’s wake word technology had at any time been the “front end” of the Google search engine, presumably Sensory would have said so clearly and precisely, and not as the outlier in a list of otherwise similar products.

wake word or voice assistant technology,” it licensed TrulyHandsfree from Sensory “for use of specific wake words and [spoken] commands.” Id. Google was then “so impressed with Sensory’s technology” that it entered into negotiations to acquire Sensory. Id. ¶ 32. An acquisition ultimately did not occur, and Google thereafter began developing its own wake word and voice assistant technologies for use on Android smartphones and tablets rather than license Sensory’s products. See id. ¶¶ 32–37.
