9 Plaintiff, ORDER GRANTING MOTION TO DISMISS 10 v.

11 FRESHWORKS INC., Re: ECF No. 23 Defendant. 12

13 14 In this patent infringement case, Plaintiff Estech Systems IP, LLC accuses Defendant 15 Freshworks Inc. of infringing two patents: U.S. Patent Nos. 8,391,298 (the “’298 Patent”) and 16 7,123,699 (the “’699 Patent”) (together, the “Asserted Patents”). The Asserted Patents are 17 directed to systems and methods for providing communications systems, including voice over IP 18 (“VoIP”) telephony. Freshworks moves to dismiss the complaint for failure to state a claim under 19 Rule 12(b)(6). ECF No. 23. After carefully reviewing the documents, the Court found this matter 20 suitable for decision without oral argument pursuant to Civil Local Rule 7-1(b). For the reasons 21 stated below, the Court GRANTS Freshwork’s Motion. 22 I. BACKGROUND 23 Estech, a Texas Corporation, is an affiliate of Estech Systems, Inc. (“ESI”). Compl. ¶ 8. 24 ESI is a US-based provider of end-to-end business phone solutions. Id. ESI offers “a full 25 solutions portfolio of modern business phone systems, including Cloud, Hybrid, Pure IP, and SIP 26 dial tone products.” Id. ¶ 11. ESI’s products include “the most integrated cloud PBX in the 27 market—the award-winning ESI Cloud PBX; Voice over IP (VoIP) products and systems; and on- 1 premises products.” Id. ¶ 12. VoIP transmits and receives voice communications over data 2 networks, such as the internet or private networks, using the internet protocol. Id. ¶ 13. 3 The ’298 Patent is titled “Phone Director in a Voice Over IP Telephone System” and 4 relates to a system that allows a user on one local area network (“LAN”) to view a list of phone 5 extensions associated with another LAN. Estech alleges Freshworks directly infringes “at least 6 claim 13” of the ’298 Patent. Compl. ¶ 36. Claim 13 recites the following: 7 13. A telecommunications system comprising: a first IP telephone coupled to a first IP server within a first LAN; 8 second and third telephone extensions coupled to a second IP server within a second LAN; 9 a WAN coupling the first LAN to the second LAN, the first LAN, the second LAN, and the WAN communicating using an IP protocol; 10 a third LAN coupled to the first and second LANs via the WAN; means for displaying on the first IP telephone a list of telephone destinations stored in the 11 second IP server in response to selection of a first input on the first IP telephone, wherein the list of telephone destinations is communicated from the second IP server 12 over the WAN to the first IP telephone; 13 means for automatically dialing the selected one of the telephone destinations for a communications link between the first IP telephone and the selected one of the 14 telephone destinations in response to selection of one of the telephone destinations from the displayed list, wherein the selection of one of the telephone destinations from 15 the displayed list is performed in response to selection of a second input on the first IP telephone by a user; 16 means for displaying on the first IP telephone a list of LANs coupled to the WAN, 17 including the second and third LANs; and means for displaying the first list in response to selection of the second LAN from the 18 displayed list of LANs. 19 The ’699 Patent is titled “Voice Mail in a Voice Over IP Telephone System” and relates 20 generally to a method of remotely accessing voicemail by streaming the message from one LAN 21 to another. Estech alleges Freshworks directly infringes “at least Claim 1” of the ’699 Patent. 22 Compl. ¶ 56. Claim 1 recites the following: 23 1. In a telecommunications system, a method comprising the steps of: storing a voice mail message in a voice mail box in a voice mail system within a first 24 LAN; 25 coupling a second LAN to the first LAN over a WAN, wherein the first LAN, the second LAN, and the WAN operate under a routable network protocol; 26 providing a sensory indication on a telecommunications device within the second LAN that the voice message is stored in the voice mail box within the first LAN; and 27 the telecommunications device accessing the voice mail system within the first LAN to listen to the voice message stored in the voice mail box, 1 wherein the step of the telecommunications device accessing the voice mail system within 2 the first LAN to listen to the voice message stored in the voice mail box further comprises the steps of: 3 establishing a channel between the first and second LANs over the WAN; coupling an audio path over the channel between the telecommunications device and the 4 voice mail box; and streaming voice data containing the voice message from the voice mail box to the 5 telecommunications device over the audio path, wherein the establishing step further 6 comprises the steps of: in response to an input at the telecommunications device, sending a user mail box 7 connection message from the second LAN to the first LAN requesting a channel, wherein the user mail box connection message includes an extension associated with 8 the telecommunications device and an identification of the voice mail box; assigning the channel by the first LAN; and 9 sending a connection established message from the first LAN to the second LAN. 10 Estech filed this case on April 26, 20241, alleging Freshworks’ software telephony 11 products, servers, and services infringe the Asserted Patents. Compl. ¶ 21. In particular, Estech 12 alleges the following list of Freshworks (1) communication equipment and services, and 13 (2) system-design services constitute the “Accused Instrumentalities” in this case: 14 Freshworks software telephony products (e.g., Freshcaller mobile app, Freshcaller 15 desktop app, Freshdesk Android app, Freshdesk iPhone app, Freshdesk iPad app, Freshdesk desktop app, Freshworks Customer Service Suite), Freshworks VoIP 16 telephony servers and services (e.g., Freshcaller, Freshcaller Cloud PBX, Freshdesk, Freshworks Neo Platform, Freshcaller voicemail system), and 17 products and services that incorporate the same or similar technology, that employ 18 VoIP to perform various functions including, but not limited to, voice calling, voicemail, directory services, and others using multiple components including, 19 but not limited to, for example, hubs, switches, routers, session border controllers, servers and the like, and the software for operating such components 20 (“Freshworks Products and Services”). 21 Compl. ¶ 21; see also id. ¶ 24 (“When this Complaint references ‘Accused Instrumentalities,’ it is 22 referring to the telecommunications and information handling systems Freshworks offers to sell, 23 sells, and makes for its customers as well as the systems its employees use that are referenced in 24

25 1 On the same day, Estech filed five separate actions against various defendants in this District based on the same patents. See Estech Sys. IP, LLC v. v. 8x8, Inc., No. 5:24-cv-2522-EJD (N.D. 26 Cal.) (dismissed); Estech Sys. IP, LLC v. Intermedia.net, Inc., No. 5:24-cv-2526-EJD (N.D. Cal.); Estech Sys. IP, LLC v. Zultys, Inc., No. 5:24-cv-2529-EJD (N.D. Cal.) (dismissed); Estech Sys. IP, 27 LLC v. Ooma, Inc., No. 5:24-cv-2527-EJD (N.D. Cal.); Estech Sys. IP, LLC v. Zoom Video Commc’ns, Inc., No. 5:24-cv-2528-EJD (N.D. Cal.). 1 paragraphs 21–23 above and are incorporated herein by reference”). 2 Estech alleges Freshworks directly infringes the Asserted Patents by making, having made, 3 using, importing, providing, supplying, distributing, selling, or offering for sale the Accused 4 Instrumentalities. Estech also brings claims for indirect and willful infringement. 5 Freshworks moves to dismiss all claims against it for failure to state a claim under Fed. R. 6 Civ. P. 12(b)(6). 7 II. LEGAL STANDARD 8 Rule 8(a) requires that a complaint contain “a short and plain statement of the claim 9 showing that the pleader is entitled to relief[.]” Fed. R. Civ. P. 8(a)(2). “To survive a motion to 10 dismiss, a complaint must contain sufficient factual matter, accepted as true, to ‘state a claim to 11 relief that is plausible on its face.’” Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009) (quoting Bell Atl. 12 Corp. v. Twombly, 550 U.S. 544, 570 (2007)). A plaintiff must “plead[] factual content that 13 allows the court to draw the reasonable inference that the defendant is liable for the misconduct 14 alleged,” which requires “more than a sheer possibility that a defendant has acted unlawfully.” Id. 15 (citing Twombly, 550 U.S. at 556). 16 Although “a court must accept as true all of the allegations contained in a complaint,” 17 “[t]hreadbare recitals of the elements of a cause of action, supported by mere conclusory 18 statements, do not suffice.” Iqbal, 556 U.S. at 678 (citing Twombly, 550 U.S. at 555). In patent 19 cases, “a plaintiff cannot assert a plausible claim for infringement under the Iqbal/Twombly 20 standard by reciting the [patent] claim elements and merely concluding that the accused product 21 has those elements. There must be some factual allegations that, when taken as true, articulate why 22 it is plausible that the accused product infringes the patent claim.” Bot M8 LLC v. Sony Corp. of 23 Am., 4 F.4th 1342, 1353 (Fed. Cir. 2021). “A plaintiff is not required to plead infringement on an 24 element-by-element basis.” Id. at 1352 (citing Nalco Co. v. Chem-Mod, LLC, 883 F.3d 1337, 25 1350 (Fed. Cir. 2018)). However, a plausible claim requires at least some factual allegations to 26 support a plausible inference that the product at issue satisfies a claim limitation. See id. at 1355. 27 1 III. DISCUSSION 2 A. Whether Estech Has Stated a Claim for Direct Infringement 3 Liability for direct infringement arises when a party “without authority makes, uses, offers 4 to sell, or sells any patented invention, within the United States or imports into the United States 5 any patented invention during the term of the patent.” 35 U.S.C. § 271(a). To plead direct 6 infringement, a plaintiff must recite “some factual allegations that, when taken as true, articulate 7 why it is plausible that the accused product infringes the patent claim.” Bot M8, 4 F.4th at 1353. 8 To satisfy the Iqbal pleading standard in a patent case, “[s]pecific facts are not necessary.” Disc 9 Disease Sols. Inc. v. VGH Sols., Inc., 888 F.3d 1256, 1260 (Fed. Cir. 2018) (quotation omitted). 10 The complaint needs to only give a defendant “fair notice of what the [infringement] claim is and 11 the ground upon which it rests.” Id. (quoting Erickson v. Pardus, 551 U.S. 89, 93 (2007)). 12 Estech alleges the “Accused Instrumentalities” infringe certain limitations of the above 13 claims using slightly different words than the claim language itself. See Compl. ¶¶ 32–35 14 (asserting infringement of the ’298 Patent); 52–55 (same as to the ’699 Patent). Freshworks 15 argues that Estech fails to state a claim of direct infringement as to either Asserted Patent because 16 Estech simply copies the language of the claim element and then states that the Accused 17 Instrumentalities meet those claims. Mot. 4. In particular, the allegations with respect to both 18 Asserted Patents fail, according to Freshworks, because (1) “Estech provides no product 19 information, details, or images to show that Freshworks performs any of the limitations” in 20 claim 13 of the ’298 Patent or claim 1 of the ’699 Patent, and (2) “Estech provides no insight as to 21 how the Accused Instrumentalities” infringe those claims. Mot. 4–6. On the first point, Estech 22 does identify the products it contends infringes. See Compl. ¶ 21 (identifying “Freshcaller mobile 23 app, Freshcaller desktop app, Freshdesk Android app, Freshdesk iPhone app, Freshdesk iPad app, 24 Freshdesk desktop app, Freshworks Customer Service Suite[]” and “Freshcaller, Freshcaller Cloud 25 PBX, Freshdesk, Freshworks Neo Platform, Freshcaller voicemail system”). And Freshworks 26 cites no authority for its suggestion that a patent plaintiff must provide “details or images to show” 27 infringement at the pleading stage. 1 Freshworks’ second point, however, is well-taken. The Federal Circuit is clear that “a 2 plaintiff cannot assert a plausible claim for infringement under the Iqbal/Twombly standard by 3 reciting the claim elements and merely concluding that the accused product has those elements.” 4 Bot M8, 4 F.4th at 1353. That is what Estech does here. The complaint lists approximately twelve 5 Freshworks products and services (Compl. ¶ 21) and then concludes that Freshworks has directly 6 infringed the Asserted Patents because Accused Functionalities have those elements (id. ¶¶ 31–35, 7 52–55). This amounts to “a mere recitation of claim elements and corresponding conclusions, 8 without supporting factual allegations” that does not plausibly allege infringement. Bot M8, 4 9 F.4th at 1355. 10 Although a “plaintiff is not required to plead infringement on an element-by-element 11 basis” as Estech points out (Mot. 4 (quoting Bot M8, 4 F.4th at 1352)), it must do more than 12 simply identify the Accused Instrumentalities. Id. (arguing that the complaint “identifies 13 Freshworks’ [Accused Functionalities],” and “[t]hus, the complaint complies with the federal 14 pleading requirements”). Estech contends that it has provided sufficient notice to Freshworks 15 because the complaint (1) “specifically identifies each infringed patent” (Opp. 5–6 (citing Compl. 16 ¶¶ 30, 51)), (2) “identif[ies] exemplary claims of each patent that are infringed by Freshworks” 17 (id. at 6 (citing Compl. ¶¶ 36, 56)), and (3) “identifies the particular systems that Freshworks uses 18 or provides in infringing the identified patent claims, along with the constituent parts of the 19 Accused Instrumentalities” (id. (citing Compl. ¶¶ 31–35, 52–55)). This argument is no different 20 than saying that Estech has identified the relevant claims of Asserted Patents and alleged that the 21 Accused Instrumentalities infringe those claims. Without any supporting factual allegations 22 beyond the conclusory allegations above, the complaint does not provide sufficient notice to 23 Freshworks. 24 Estech insists that a result for Freshworks would impose on Estech a heightened pleading 25 standard. Not so. To be clear, the Court is not endorsing the argument that patent plaintiffs are 26 required at the pleading stage to identify information that will be later exchanged pursuant to the 27 Local Patent Rules, including claim charts and infringement contentions. Estech must, however, 1 need include additional factual allegations to support a plausible claim of infringement beyond just 2 identifying the products and claiming they infringe. See, e.g., Cyph, Inc. v. Zoom Video 3 Commc’ns, Inc., No. 22-CV-00561-JSW, 2022 WL 1556417, at *3 (N.D. Cal. May 17, 2022) 4 (dismissing complaint and concluding that direct infringement claims “would not satisfy the 5 pleading requirements under Twombly because they do nothing more than allege Zoom infringes 6 by reciting the relevant claim language verbatim”); see also Atlas IP LLC v. Pac. Gas & Elec. Co., 7 No. 15-CV-05469-EDL, 2016 WL 1719545, at *3 (N.D. Cal. Mar. 9, 2016) (dismissing direct 8 infringement claim and explaining that “simply reciting some of the elements of a representative 9 claim and then describing generally how an accused product operates, without specifically tying 10 the operation to any asserted claim or addressing all of the claim requirements, is insufficient.”).2 11 In sum, due to the conclusory nature of the allegations which merely track the claim 12 language, Estech’s allegations do not plausibly allege direct infringement as to the Asserted 13 Patents. The Court therefore GRANTS Freshworks’ Motion and DISMISSES WITH LEAVE TO 14 AMEND Estech’s claim for direct infringement of the Asserted Patents. 15 B. Whether Estech Has Stated a Claim for Indirect or Willful Infringement 16 Having failed to allege any plausible claim for direct infringement of the Asserted Patents, 17 Estech’s indirect and willful infringement claims also fail. See e.Digital Corp. v. iBaby Labs, Inc., 18 No. 15-CV-05790-JST, 2016 WL 4427209, at *5 (N.D. Cal. Aug. 22, 2016) (dismissing indirect 19 infringement claim where complaint failed to state direct infringement claim); see also Yangtze 20 Memory Techs. Co., Ltd. v. Micron Tech., Inc., No. 23-CV-05792-RFL, 2024 WL 3422598, at *3 21

22 2 Estech’s cited cases do not change this result. First, the Court does not find persuasive Estech’s 23 reliance on other district court decisions denying motions to dismiss. See Opp. 4. Second, Regents of University of Michigan is equally unhelpful because the court there denied a motion to 24 dismiss a patent infringement complaint where the arguments before it were “more appropriately presented during claim construction.” Regents of Univ. of Michigan v. Leica Microsystems Inc., 25 No. 19-CV-07470-LHK, 2020 WL 2084891, at *6 (N.D. Cal. Apr. 30, 2020). No similar arguments are before the Court on this Motion. Finally, the court in Windy City Innovations, LLC 26 v. Microsoft Corp. declined to dismiss a patent infringement complaint which contained sufficient factual allegations regarding the accused products and services; factual allegations lacking in 27 Estech’s complaint. 193 F. Supp. 3d 1109, 1115 (N.D. Cal. 2016); see also id. at ECF No. 1 ¶¶ 16–23. ] (N.D. Cal. July 16, 2024) (dismissing willful infringement claim where complaint failed to state a 2 || claim for direct infringement). 3 The Court therefore GRANTS Freshwork’s Motion and DISMISSES WITH LEAVE TO 4 || AMEND Estech’s claim for indirect infringement of the Asserted Patents. 5 || IV. CONCLUSION 6 For the foregoing reasons, Freshwork’s Motion is GRANTED WITH LEAVE TO 7 || AMEND. Any amended complaint must be filed within 21 days of this Order. 8 9 IT IS SO ORDERED. of 11 EDWARD J. DAVILA 12 United States District Judge
