12 Plaintiff, ORDER GRANTING MOTION TO 13 v. DISMISS

14 RESMED INC.; RESMED CORP.; and [ECF No. 9] RESMED HOLDINGS PTY LIMITED, 15 Defendants. 16 17 18 Pending before the Court is the Defendants’ Motion to Dismiss. ECF No. 9. Plaintiff 19 filed an opposition, and Defendants filed a reply. ECF Nos. 15, 17. On March 12, 2025, 20 the Court held a hearing on the motion and took the matter under submission. ECF No. 19. 21 After due consideration and for the reasons discussed below, the Court GRANTS 22 Defendants’ motion. 23 I. BACKGROUND 24 On July 24, 2024, Plaintiff filed a complaint alleging that Defendants infringed his 25 patent, U.S. Patent No. 9,639,150 (“the ’150 Patent”). ECF No. 1. The ’150 Patent is titled 26 “Powered Physical Displays on Mobile Devices” and was issued on May 2, 2017. Id. ¶ 11. 27 Plaintiff alleges that the patent discloses “various forms and applications of interactive 28 powered display apparatuses and methods, for example, physically and/or electronically 1 interactive communication enabled end user devices adaptable for use with various other 2 || distinct devices and may be remotely controlled to deliver in real-time one or more stimuli, 3 || such as air pressure.” Id. ¥ 13. 4 While the disclosures in the Patent specifications are fairly broad and purported 5 ||to cover various interactive powered display apparatuses and methods geared towards 6 || different purposes, the claims of the *150 Patent are directed at methods for treating 7 ||patients. See °150 Patent at 16:47-48—_The patent includes one embodiment as an 8 ||exemplar: 9 10 iW _ 20a 2) Vf | = SC) (Lit —20e A) | IS 8 = 14 | lh | 12A (5 | AY Mn. f 15 I /\ WK i 14A SS PRD a Toy 17 =—-r = 18 California Boston 19 0 The patent further describes this embodiment as follows: FIG. 12 generally represents remotely located doctors, therapists, nurses, 21 eldercare professionals, and others using remotely controlled physical and/or 22 electronically interactive devices to help or interact with people or animals 3 with or without locally available human assistants. For example only, a doctor may test the vital signs, strength and/or muscle/nerve reactions of a remote 24 patient while preferably video conferencing with a helper or the patient. 5 Nurses may videoconference and physically and/or electronically interact, treat or help patients perform various tasks. 26 Home based patients may be provided with remotely released medicine vaults 27 under the control and supervision of a qualified remotely located person, 28 whom may also verify pill and/or liquid ingestion, etc. One remote therapist

1 may work with several patients at the same time allowing the patients to remain in their respective dwellings. Various forms of physically and/or 2 electronically interactive devices may be designed and manufactured as 3 required for various recovery, therapeutic, or many other remote interactive situations (hands on customer service, etc.). 4 5 ’150 Patent at 12:56-13:8. 6 Plaintiff alleges that Defendants manufacture and sell medical devices, for example, 7 sleep devices and ventilation devices. Id. ¶ 7. The accused devices in this case include 8 diagnostic and pulmonary treatment devices, including Defendants’ Airsense 10 series, 9 Airsense 11 series, AirCurve 10 ASV, AirCurve 10 ST-A, AirCurve 10 VAuto, S, ST, 10 AirCurve 11, AirView software, and myAir software. Id. ¶ 1. Plaintiff asserts one cause of 11 action for patent infringement. Id. ¶¶ 15-26. 12 II. LEGAL STANDARDS 13 A motion to dismiss under Federal Rule of Civil Procedure 12(b)(6) for failure to 14 state a claim tests the legal sufficiency of a plaintiff’s claim. Navarro v. Block, 250 F.3d 15 729, 732 (9th Cir. 2001). When considering the motion, the court must accept as true all 16 well-pleaded factual allegations in the complaint. Bell Atlantic Corp. v. Twombly, 556 U.S. 17 544, 555 (2007). The court need not accept as true legal conclusions cast as factual 18 allegations. Id.; Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009) (“[t]hreadbare recitals of the 19 elements of a cause of action, supported by mere conclusory statements” are insufficient). 20 Patent eligibility under 35 U.S.C. § 101 may be raised on a 12(b)(6) motion. Genetic Techs. 21 Ltd. v. Merial LLC, 818 F.3d 1369, 1373 (Fed. Cir. 2016). However, this is limited to the 22 circumstance where “there are no factual allegations that, taken as true, prevent resolving 23 the eligibility question as a matter of law.” Aatrix Software, Inc. v. Green Shades Software, 24 Inc., 882 F.3d 1121, 1125 (Fed. Cir. 2018). 25 Section 101 defines the subject matter eligible for patent protection as “[w]hoever 26 invents or discovers any new and useful process, machine, manufacture, or composition of 27 matter, or any new and useful improvement thereof, may obtain a patent therefor, subject 28 to the conditions and requirements of this title.” 35 U.S.C. § 101. Our courts have 1 recognized that laws of nature, natural phenomena, and abstract ideas are exceptions to 2 patentability. Mayo Collaborative Servs. v. Prometheus Lab’ys, Inc., 566 U.S. 66, 70 3 (2012). The Supreme Court has enunciated a two-step test for courts to apply when 4 determining whether a patented invention targets an abstract idea. The first part of this 5 framework is to determine “whether the claims at issue are directed to a patent-ineligible 6 concept.” Alice Corp. Pty. v. CLS Bank Int’l, 573 U.S. 208, 217 (2014). If the answer is 7 yes, then the second part of this framework asks whether that patent contains an “inventive 8 concept sufficient to ‘transform’ the claimed abstract idea into a patent-eligible 9 application.” Id. at 221 (citation omitted). 10 III. DISCUSSION 11 As a threshold matter, the parties both focus on Claim 1 of the ’150 Patent as a 12 representative claim. Claim 1 is the only independent claim of that patent and Plaintiff 13 himself alleges that the claim is “exemplary” of the patent. ECF No. 1 ¶ 16. Thus, the Court 14 finds it appropriate to consider the § 101 patentability issue with this claim in mind. See, 15 e.g., Mobile Acuity Ltd. v. Blippar Ltd., 110 F.4th 1280, 1290 (Fed. Cir. 2024) (“Limiting 16 the analysis of a § 101 challenge to representative claims is proper when the claims at issue 17 are ‘substantially similar and linked to the same’ ineligible concept.”). 18 Claim 1 of the ’150 Patent claims the following: 19 1.
