IV. Analysis of Infringement Allegations

'339 Patent Infringement Allegations

Claim Element (from Independent Claim 1)	Alleged Infringing Functionality	Complaint Citation	Patent Citation
obtaining at least one first biological signal from a user...indicating a presence of the user on the bed device	The Orion system's "embedded sensors" are alleged to sense the user's presence on the bed device.	¶76	col. 5:25-34
determining a first control signal and a time to send the first control signal...based on a bedtime associated with the user, the presence of the user, or both	The Orion system allegedly determines a "thermoregulation set point" and uses its technology to cool or heat the body based on biometrics and user presence.	¶77	col. 7:51-64
sending the first control signal to the bed device at the determined time to turn the bed device on or off and set the bed device to the first temperature	The Orion system allegedly sends signals to adjust temperature, as depicted in a marketing image showing "Automatic temperature adjustment all night."	¶78	col. 7:65-8:4
obtaining, while the bed device is turned on, at least one second biological signal from the user, wherein the at least one second biological signal is different from the at least one first biological signal	The Orion system allegedly obtains a second biological signal via a "Sleep Optimization Test" or from "embedded sensors" that obtain biological signals during sleep.	¶79	col. 9:1-5
determining a second control signal...to adjust the temperature of the bed device to a second temperature in response to the obtained at least one second biological signal	The Orion system allegedly determines and adjusts the user's temperature schedule based on a "Sleep Optimization Test" or recommendations from "Sleep Insights."	¶80	col. 12:1-19
sending the second control signal to the bed device to adjust the temperature of the bed device to the second temperature	The Orion system allegedly "automatically provides control signals to adjust the temperature based on recommendations generated in response to biological signals."	¶81	col. 20:20-23

• Identified Points of Contention:
  • Technical Question: The core of the infringement theory rests on the system obtaining a "second biological signal" that is "different" from the first. The complaint's allegation is based on a "Sleep Optimization Test" or ongoing sensor readings Compl. ¶79 A central question will be whether the signal from this test or ongoing monitoring is provably "different" in kind from the initial presence-detecting signal, as required by the claim, or merely a subsequent measurement of the same signal type.
  • Scope Question: The complaint alleges that Defendants' testing and development activities constitute infringement Compl. ¶¶72 Compl. ¶83 However, it also includes multiple allegations that the accused product was "incomplete" and "under development" during the relevant period Compl. ¶63 This raises the question of whether an incomplete or non-functional product could perform all steps of the claimed method.

'240 Patent Infringement Allegations

Claim Element (from Independent Claim 1)	Alleged Infringing Functionality	Complaint Citation	Patent Citation
obtaining at least one first biological signal from a first user...indicating a presence of the first user on a first zone of the bed device	The Orion system's "embedded smart sensors" allegedly track a user's biometrics and presence on one side of the bed.	¶96	col. 6:60-63
obtaining at least one second biological signal from a second user...indicating a presence of the second user on a second zone...adjacent the first zone	The Orion system is touted as having "DUAL-ZONE COOLING TECHNOLOGY" and providing "unique sleep temperature profiles for each partner," which allegedly requires detecting a second user in a second zone.	¶96	col. 6:60-63
generating a plurality of control signals...to set the temperature of the second zone to a second temperature that is different from the first temperature	The system allegedly generates different control signals for each side of the bed, as evidenced by marketing for "dual-zone" features and an app screenshot showing separate controls for "John" and "Guest."	¶97	col. 7:15-24
wherein the first instruction is based at least in part on a first user-specified preference...and the second instruction is based at least in part on a second user-specified preference	The system's "dual-zone" feature allegedly allows each side to be regulated independently based on user needs and preferences, and recommendations are generated from "Sleep Insights."	¶97	col. 7:15-24
sending the plurality of control signals...such that the first and second zones are heated or cooled differently	The system allegedly offers "personalized cooling for each sleeper" and "dual-zone temperature control," which allows for separate sleep climates.	¶98	col. 7:6-14

• Identified Points of Contention:
  • Scope Question: The claim requires temperature settings to be "based at least in part on a...user-specified preference." The complaint alleges Orion's system is "AI-powered" and "learns your unique thermal profile" Compl. ¶39 A key dispute may be whether an AI-inferred profile qualifies as a "user-specified preference," or if the claim requires more direct user input that the accused system may lack.
  • Technical Question: Infringement requires the system to actually create two different temperatures. The complaint provides a screenshot of the Orion app interface showing two separately controllable zones Compl. p. 38 The factual question will be whether the accused system, when in operation, actually sends different control signals to achieve different temperatures in the two zones as claimed.

V. Key Claim Terms for Construction

For the '339 Patent

• The Term: "biological signal"
• Context and Importance: This term appears throughout claim 1 and its interpretation is fundamental to the infringement analysis. The claim requires a "first biological signal" and a "second biological signal" that is "different" from the first. The scope of what constitutes a "biological signal" will determine if the accused system meets these limitations. Practitioners may focus on this term because if a simple presence or temperature reading is a "biological signal," the analysis then shifts to whether the system later obtains a "different" one, such as heart rate.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification states the term is a synonym for "bio signal" and that user sensors can monitor signals "such as the heart rate, the breathing rate, the temperature, motion, or presence" of a user '339 Patent, col. 3:56-57 '339 Patent, col. 4:63-65 This supports a broad definition including simple presence.
  • Evidence for a Narrower Interpretation: Specific embodiments focus on more complex signals like heart rate and breathing rate extracted from a "compound bio signal" '339 Patent, col. 9:1-24 A party could argue that in the context of the full claim, the term implies more than just a binary presence detection, which is separately called out in the first limitation.

For the '240 Patent

• The Term: "user-specified preference"
• Context and Importance: This term is the basis for generating the different temperatures in claim 1. Its definition is critical to determining whether Orion's AI-driven system infringes. If the term is construed to require explicit input from a user (e.g., setting a specific temperature), infringement may be more difficult to prove than if it is construed to cover preferences inferred by an algorithm.
• Intrinsic evidence for Interpretation:
  • Evidence for a Broader Interpretation: The claim requires the instruction to be based "at least in part on" the preference, suggesting the preference does not need to be the sole or even primary input. The specification also discusses using "historical bio signals" and "exercise data" to determine temperature, which could be interpreted as proxies for a user's preference '240 Patent, col. 11:1-15
  • Evidence for a Narrower Interpretation: The patent repeatedly contrasts automated determinations with "user-specified" inputs like a "user-specified wake-up time" or "user-specified bed temperature" '240 Patent, col. 8:51-52 '240 Patent, col. 11:10-11 This suggests that "user-specified" implies a conscious choice or setting made by the user, as distinct from a system-inferred value.

VI. Other Allegations

• Indirect Infringement: The complaint alleges that Defendants induced infringement by third-party customers through advertising, user guide manuals, and other support materials that instruct on the use of the accused products Compl. ¶85 Compl. ¶102 It further alleges that Defendant BFG induced and contributed to infringement by providing manufacturing, logistical, and design support to Orion, knowing the components were for an infringing combination with no substantial non-infringing use Compl. ¶85 Compl. ¶86
• Willful Infringement: Willfulness is alleged based on Defendants' purported actual knowledge of the asserted patents since at least October 9, 2025, the date the complaint in a prior litigation was filed Compl. ¶88 Compl. ¶105 For conduct preceding that date, the complaint alleges willful blindness, asserting that a reasonable company would have investigated Plaintiff's patent portfolio before launching a directly competitive product Compl. ¶45

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

• A central issue will be one of definitional scope: for the '339 patent, can the sequence of operations in the accused "AI-powered" system be mapped to the claim's requirement for a "first biological signal" followed by a "different" "second biological signal," or is there a mismatch in the type or sequence of data used?
• A second core issue will be the interpretation of user intent versus automation: for the '240 patent, does the term "user-specified preference" require explicit input from the user, or can it be satisfied by an algorithm that "learns" and applies a thermal profile, and what evidence shows that the accused system practices either interpretation?
• A key evidentiary question will be one of operative reality versus advertisement: the complaint alleges that many of the accused product's advertised features were "incomplete" or non-existent at the time of sale. This raises a fundamental factual question for the court: when, if ever, did the accused system actually become capable of performing the patented methods, and does the evidence of infringement align with that timeline?
