• Patent Identification: U.S. Patent No. 12,370,339 (Methods and Systems for Gathering and Analyzing Human Biological Signals), issued July 29, 2025 Compl. ¶18

Technology Synopsis

This patent describes a method of operating a bed device based on a sequence of events. The system first determines a time to send an initial control signal to turn the device on and set a first temperature, based on a user's presence or a pre-set bedtime ('339 Patent, claim 1, as recited in Compl. ¶79). After the device is on, it obtains a second, different biological signal from the user and then determines and sends a second control signal to adjust the temperature in response to this new signal ('339 Patent, claim 1, as recited in Compl. ¶79). This covers a pre-conditioning phase followed by a dynamic adjustment phase.

IV. Analysis of Infringement Allegations

10,792,461 Infringement Allegations

Claim Element (from Independent Claim 1)	Alleged Infringing Functionality	Complaint Citation	Patent Citation
at least one sensor that is a part of said bed device... configured to detect a biological signal of a user...	The Accused Product's "Smart Cover" includes "embedded smart sensors" that "track your sleep pattern and biometrics."	¶52	col. 5:8-14
a temperature control device operatively coupled to said portion of said bed device, wherein said temperature control device is configured to regulate said temperature...	The Accused Product comprises a "Control Tower" and hydro-cooling system that provides "personalized cooling for each sleeper" and "automatic temperature adjustment all night."	¶53	col. 5:31-35
a processor... configured to identify said user from a plurality of users of said bed device based on said biological signal, and regulate said temperature... based on said user's identity	The "Orion App" is a processor that allegedly identifies users and provides personalized temperature control. A marketing image shows distinct temperature settings for two different users, "Caroline" and "Alex."	¶¶54-55	col. 7:4-10
wherein biological signal data to identify each user of said plurality of users is stored for access by said processor...	The Accused Product is advertised as being "truly personalized to you based on your sleep data," which implies the storage and use of user-specific biological signal data to enable personalization.	¶56	col. 7:65-68

• Identified Points of Contention:
  • Scope Questions: A central question will be the scope of "identify said user... based on said biological signal." The complaint presents a marketing image showing different names and temperatures as evidence Compl. ¶51 The court may need to determine if this claim requires a real-time biometric authentication process or if it is met by a system that detects presence in a pre-assigned zone that is linked to a static user profile.
  • Technical Questions: What evidence does the complaint provide that the Accused Product actually performs identification based on the biological signal itself, beyond detecting presence? The allegations rely heavily on marketing materials, and the technical mechanism by which the Orion system distinguishes between "Caroline" and "Alex" if they were to switch sides of the bed will be a key factual question for infringement.

12,377,240 Infringement Allegations

Claim Element (from Independent Claim 1, via Claim 29)	Alleged Infringing Functionality	Complaint Citation	Patent Citation
obtaining at least one first biological signal from a first user... on a first zone of the bed device	The Accused Product's "embedded sensors sense where you are in your sleep cycle and constantly adjust your body temperature."	¶67	col. 5:16-24
obtaining at least one second biological signal from a second user... on a second zone of the bed device adjacent the first zone	The system's "dual-zone temperature control" functionality for two independent users implies the ability to obtain a second biological signal from a second user in a separate zone.	¶68	col. 5:16-24
generating a plurality of control signals... comprising... a first instruction to set the temperature of the first zone... and a second instruction to set the temperature of the second zone to a second temperature that is different from the first temperature, wherein the first instruction is based at least in part on a first user-specified preference... and the second instruction is based... on a second user-specified preference	The "Orion App" and "Smart Mode" are alleged to adjust temperatures for two users independently, based on each user's specified preferences, as evidenced by marketing materials showing "Personalized cooling for each sleeper."	¶69	col. 8:5-14
sending the plurality of control signals to at least one respective temperature control device... such that the first and second zones are heated or cooled differently	The Accused Product is advertised as allowing a user and their partner "to enjoy your ideal sleep climate individually," which suggests sending different control signals to create two distinct thermal zones.	¶70	col. 6:50-53
A sleep system comprising a processor and a memory... storing instructions for the processor to implement the method of claim 1.	The combination of the "Smart Cover," "Control Tower," and "Orion App" constitutes a system with a processor and memory that executes the accused dual-zone thermoregulation method.	¶71	col. 4:20-24

• Identified Points of Contention:
  • Scope Questions: What is the required nexus for an instruction to be "based at least in part on a... user-specified preference"? Does a one-time setting by the user suffice, or does the claim require a more dynamic interaction where the preference itself is adjusted or weighted based on real-time conditions?
  • Technical Questions: The complaint cites marketing claims of dual-zone control (Compl. ¶¶69-70). A key evidentiary question will be how the Accused Product technically achieves and maintains two distinct thermal zones and whether its method of generating control signals in response to user-specific data aligns with the method claimed in the patent.

V. Key Claim Terms for Construction

For the '461 Patent

• The Term: "identify said user from a plurality of users... based on said biological signal"
• Context and Importance: This term is critical because it defines the personalization aspect for a multi-user environment. The infringement analysis will turn on whether the accused system's method of distinguishing between users meets this limitation, or if it simply relies on which side of the bed a person is on.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification states the system "will correctly identify which user is sleeping in which zone by identifying the user based on any of the following signals alone, or in combination: heart rate, breathing rate, body motion, or body temperature" '461 Patent, col. 7:4-10 Plaintiff may argue this language supports that using any of these signals to associate a person in a zone with a profile constitutes "identification."
  • Evidence for a Narrower Interpretation: Defendant may argue that "identify... based on" requires more than simple presence detection; it implies the biological signal itself contains unique, identifying characteristics that are analyzed. Claim 2, for instance, specifies identifying users based on first and second biological signals, which could suggest a more complex comparison is contemplated by the invention '461 Patent, claim 2

For the '240 Patent

• The Term: "based at least in part on a... user-specified preference"
• Context and Importance: This term is central to the link between the user's input and the system's autonomous action. Practitioners may focus on this term because its interpretation will determine whether a static preference set by a user is sufficient to meet the claim, or if a more dynamic use of that preference is required.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: Claim 1 recites generating control signals "in response to the obtained... biological signal" and that the instructions are "based at least in part on a... user-specified preference" ('240 Patent, claim 1, as recited in Compl. ¶64). This could be read as two separate inputs to the system's logic, where the presence of a user (from the biological signal) triggers the application of a stored preference.
  • Evidence for a Narrower Interpretation: The specification discusses regulating temperature based on historical data and sleep phases, in addition to user preferences ('240 Patent, specification generally, e.g., '461 Patent, col. 8:1-14). A defendant might argue that "based on" should be interpreted in this richer context, requiring more than just recalling a single preference value.

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement of infringement under 35 U.S.C. § 271(b) against both Defendants. The allegations are based on Defendants publishing specifications, marketing materials, and user guides that allegedly instruct and encourage customers to use the Accused Product in an infringing manner Compl. ¶57 Compl. ¶72 It is also alleged that Defendant BFG induces infringement by providing manufacturing and importation support to Defendant Orion Compl. ¶57
• Willful Infringement: The complaint alleges willful infringement based on two theories. First, it alleges willful blindness, arguing that Defendants, by creating a directly competing product and performing a side-by-side comparison, would have or should have investigated Plaintiff's patent portfolio Compl. ¶36 Second, it alleges actual knowledge of the patents at least from the time the original complaint was served Compl. ¶59

VII. Analyst's Conclusion: Key Questions for the Case

• A threshold issue will be one of product status and evidence: Was the "Orion Sleep System" an infringing product offered for sale, as Plaintiff alleges based on marketing, pre-order pages, and user testimonials Compl. ¶29 Compl. ¶45, or will discovery show it was an "incomplete" prototype with materially different features, as Defendant has allegedly claimed Compl. ¶46? The resolution of this factual dispute is foundational to the entire infringement case.
• A core issue will be one of definitional scope: Can the claim term "identify said user... based on said biological signal" from the '461 patent be construed to cover a system that assigns a user profile to a specific zone of the bed, as suggested by Orion's marketing materials Compl. ¶51, or does it require a more robust, real-time biometric authentication?
• A key question will be one of operational mechanics: Does the accused "dual-zone" system function in a way that meets the specific, multi-step method claimed in the '240 patent? The court will need to look beyond marketing claims to determine if the system technically obtains signals from two users and generates distinct temperature instructions "based at least in part on" their individual preferences, as the claim requires.
