Western Digital Technologies, Inc. et al v. Viasat, Inc. Doc. 75 1 2 3 4 UNITED STATES DISTRICT COURT 5 NORTHERN DISTRICT OF CALIFORNIA 6 7 WESTERN DIGITAL TECHNOLOGIES, INC., et al., 8 Plaintiffs, 9 v. 10 Case No. 22-cv-04376-HSG ORDER GRANTING MOTION TO DISMISS COUNT THREE OF THE AMENDED COMPLAINT Re: Dkt. No. 40 VIASAT, INC., 11 United States District Court Northern District of California Defendant. 12 13 Pending before the Court is Defendants’ motion to dismiss Count Three of Plaintiffs’ 14 Amended Complaint. See Dkt. No. 40 (“Mot.”). The Court found this matter appropriate for 15 disposition without oral argument and took the matter under submission. See Civil L.R. 7-1(b); 16 Dkt. No. 63. For the following reasons, the Court GRANTS Defendants’ motion to dismiss with 17 leave to amend. 18 I. 19 BACKGROUND Plaintiffs are five companies: Western Digital Technologies, Inc. (“WDT”); Western 20 Digital Ireland Ltd. (“WDI”); SanDisk 3D IP Holdings Ltd. (“SD3D”); SanDisk Technologies 21 LLC (“SDT”); and SanDisk Storage Malaysia Sdn. Bhd (“SDSM”). See Dkt. No. 38, ¶¶ 3–10. In 22 the Amended Complaint, Plaintiffs allege that Defendant Viasat, Inc. infringed claims of U.S. 23 Patent Nos. 9,424,400 (the “’400 patent”); 10,447,667 (the “’667 patent”); and 8,504,834 (the 24 “’834 patent”). See id. As relevant to this motion, Count Three of the Amended Complaint 25 alleges that Defendant’s “media streaming systems and software” infringe at least Claim 14 of the 26 ’834 patent, which is entitled “Method and system for activation of local content with legacy 27 streaming systems” and was issued by the USPTO on August 6, 2013. Id. at ¶¶ 49, 52. 28 Dockets.Justia.com Claim 14 of the ’834 patent recites: 1 2 14. A method for activation of local content, the method comprising: 3 performing the following in a host device in communication with a storage device storing encrypted content: 4 receiving a stream of data from a network; 5 deriving a key from the received stream of data; and 6 decrypting the encrypted content using the key derived from the received stream of data. United States District Court Northern District of California 7 8 Id. at ¶ 53, see also Dkt No. 38-3. Defendants now move to dismiss Count Three under Fed. R. 9 Civ. P. 12(b)(6), on the ground that the asserted claims of the ’834 patent are patent-ineligible 10 under 35 U.S.C. § 101. 11 II. LEGAL STANDARD 12 A. 13 Rule 8(a) requires that a complaint contain “a short and plain statement of the claim 14 showing that the pleader is entitled to relief[.]” Fed. R. Civ. P. 8(a)(2). A defendant may move to 15 dismiss a complaint for failing to state a claim upon which relief can be granted under Rule 16 12(b)(6). “Dismissal under Rule 12(b)(6) is appropriate only where the complaint lacks a 17 cognizable legal theory or sufficient facts to support a cognizable legal theory.” Mendiondo v. 18 Centinela Hosp. Med. Ctr., 521 F.3d 1097, 1104 (9th Cir. 2008). To survive a Rule 12(b)(6) 19 motion, a plaintiff must plead “enough facts to state a claim to relief that is plausible on its face.” 20 Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570 (2007). A claim is facially plausible when a 21 plaintiff pleads “factual content that allows the court to draw the reasonable inference that the 22 defendant is liable for the misconduct alleged.” Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009). In 23 reviewing the plausibility of a complaint, courts “accept factual allegations in the complaint as 24 true and construe the pleadings in the light most favorable to the nonmoving party.” Manzarek v. 25 St. Paul Fire & Marine Ins. Co., 519 F.3d 1025, 1031 (9th Cir. 2008). Nonetheless, courts do not 26 “accept as true allegations that are merely conclusory, unwarranted deductions of fact, or 27 unreasonable inferences.” In re Gilead Scis. Secs. Litig., 536 F.3d 1049, 1055 (9th Cir. 2008). Motion to Dismiss 28 2 1 B. Section 101 Patent-Eligible Subject Matter Section 101 of the Patent Act describes the scope of patentable subject matter as 2 3 4 5 6 7 encompassing “any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof.” 35 U.S.C. § 101. It is well settled that “laws of nature, natural phenomena, and abstract ideas are not patentable.” See Alice Corp. Pty. v. CLS Bank Int’l, 573 U.S. 208, 216 (2014). These categories are not patent-eligible because “they are the basic tools of scientific and technological work,” which are “free to all men and reserved exclusively to none.” Mayo Collaborative Servs. v. Prometheus Labs., 566 U.S. 66, 71 (2012) (citations 8 omitted). Allowing patent claims for laws of nature, natural phenomena, and abstract ideas would 9 10 United States District Court Northern District of California 11 “tend to impede innovation more than it would tend to promote it,” thereby thwarting the primary object of the patent laws. Id. However, the Supreme Court has also recognized the need to “tread carefully in construing this exclusionary principle lest it swallow all of patent law.” Alice, 573 12 U.S. at 217. 13 The Supreme Court and Federal Circuit have articulated a two-part test for determining 14 15 whether a claim’s subject matter is patent-eligible. First, the Court “determine[s] whether a claim is ‘directed to’ a patent-ineligible abstract idea.” Content Extraction & Transmission LLC v. Wells 16 Fargo Bank, 776 F.3d 1343, 1346–47 (Fed. Cir. 2014) (citation omitted). If so, the Court then 17 “consider[s] the elements of the claim—both individually and as an ordered combination—to 18 assess whether the additional elements transform the nature of the claim into a patent-eligible 19 20 21 22 23 application of the abstract idea.” Id. at 1347. “This is the search for an ‘inventive concept’— something sufficient to ensure that the claim amounts to ‘significantly more’ than the abstract idea itself.” Id. (quotation omitted). “[W]hether a claim recites patent eligible subject matter is a question of law which may contain underlying facts.” Berkheimer v. HP Inc., 881 F.3d 1360, 1368 (Fed. Cir. 2018). The 24 Federal Circuit has repeatedly affirmed that patent eligibility under 35 U.S.C. § 101 may be 25 26 properly determined at the motion to dismiss stage, “before claim construction or significant discovery has commenced.” Trinity Info Media, LLC v. Covalent, Inc., 72 F.4th 1355, 1361–62 27 (Fed. Cir. 2023) (citing Cleveland Clinic Found. v. True Health Diagnostics LLC, 859 F.3d 1352, 28 3 United States District Court Northern District of California 1 1360 (Fed. Cir. 2017)). 2 III. ANALYSIS 3 A. 4 The Court begins with Plaintiffs’ procedural argument that Defendant has waived its patent 5 eligibility arguments by failing to bring them in conjunction with its prior Rule 12(b)(1) motion to 6 dismiss. See Dkt. No. 53 (“Opp.”) at 5. Federal Rule of Civil Procedure 12(g)(2) states that 7 “[e]xcept as provided in Rule 12(h)(2) or (3), a party that makes a motion under this rule must not 8 make another motion under this rule raising a defense or objection that was available to the party 9 but omitted from its earlier motion.” Fed. R. Civ. P. 12(g)(2). “The consequence of omitting a Rule 12(g)(2) Waiver 10 defense from an earlier motion under Rule 12 depends on the type of defense omitted.” In re 11 Apple iPhone Antitrust Litig., 846 F.3d 313, 317 (9th Cir. 2017), aff’d sub nom. Apple Inc. v. 12 Pepper, 139 S. Ct. 1514 (2019). As relevant here, a defendant who omits a defense under Rule 13 12(b)(6) does not waive that defense; instead, the defense may be raised subsequently “(A) in any 14 pleading allowed or ordered under Rule 7(a); (B) by a motion under Rule 12(c); or (C) at trial.” 15 Fed. R. Civ. P. 12(h)(2). 16 Accordingly, Defendant’s previous failure to bring a Rule 12(b)(6) motion as to patent 17 eligibility did not waive its defense under 35 U.S.C. § 101. Instead, the question before the Court 18 is whether to consider Defendant’s argument in this motion or require Defendant to bring another 19 motion under Rule 12(c). While a Rule 12(c) motion would be filed after pleadings are closed, it 20 would be “functionally identical” to a Rule 12(b)(6) motion and the same legal standard would 21 apply. See Google LLC v. EcoFactor, Inc., 602 F. Supp. 3d 1265, 1268 (N.D. Cal. 2022). In such 22 cases, the Ninth Circuit has recognized that “[d]enying late-filed Rule 12(b)(6) motions and 23 relegating defendants to the three procedural avenues specified in Rule 12(h)(2) can produce 24 unnecessary and costly delays, contrary to the direction of Rule 1.” In re Apple iPhone Antitrust 25 Litig., 846 F.3d at 318. In the interest of judicial economy, the Court will exercise its discretion 26 here and consider Defendant’s patent eligibility arguments in this motion instead of requiring 27 Defendants to bring the same argument as a Rule 12(c) motion. 28 4 1 B. Patent Eligibility When assessing patent eligibility under 35 U.S.C. § 101, “[c]ourts may treat a claim as 2 representative in certain situations, such as if the patentee does not present any meaningful 3 argument for the distinctive significance of any claim limitations not found in the representative 4 5 6 claim or if the parties agree to treat a claim as representative.” Berkheimer, 881 F.3d at 1365. Here, Plaintiff does not object to Defendant’s treatment of claim 14 as representative of the asserted claims of the ’834 patent, or present any “meaningful argument” for the distinctive 7 significance of any claim limitations not found in claim 14. Accordingly, the Court treats claim 8 14 of the ’834 patent as representative. 9 10 i. Alice Step One At step one of the Alice inquiry, the Court finds that claim 14 of the ’834 patent is directed 11 United States District Court Northern District of California to the abstract idea of delivering and deriving a decryption key from a stream of data. In this 12 13 14 15 16 17 analysis, the Court first asks “what the patent asserts to be the focus of the claimed advance over the prior art.” Yu v. Apple Inc., 1 F.4th 1040, 1043 (Fed. Cir. 2021), cert. denied, 142 S. Ct. 1113 (2022); see also TecSec, Inc. v. Adobe Inc., 978 F.3d 1278, 1292 (Fed. Cir. 2020) (“We have approached the Step 1 ‘directed to’ inquiry by asking ‘what the patent asserts to be the “focus of the claimed advance over the prior art.” ’ ” (quoting Solutran, Inc. v. Elavon, Inc., 931 F.3d 1161, 1168 (Fed. Cir. 2019)). Here, the ’834 patent describes prior art systems in which content is 18 decrypted by use of a decryption key obtained by contacting a DRM server, which is stated to 19 20 have a number of efficiency and cost drawbacks. ’834 patent at 1:13–22, 2:32–35. To solve this problem, the ’834 patent describes systems which, instead of contacting a DRM server, derive the 21 encryption key from a stream of data obtained from a streaming server. Id. at 2:1–45. 22 Accordingly, claim 14 is directed to the idea of decrypting stored content using a decryption key 23 24 that is “derived from” “a stream of data received from the network.” Id. at claim 14; see also Opp. at 9 (arguing that “the ‘834 patent . . . is directed to a patent-eligible technological improvement 25 related to delivery of decryption keys and related methods in a specific unconventional way.” 26 (emphasis added)). 27 The Court finds that delivering and deriving a decryption key from a stream of data is a 28 5 United States District Court Northern District of California 1 patent-ineligible abstract idea. The Federal Circuit has explained that “a relevant inquiry at Alice 2 Step 1 is whether the claims in the patent focus on a specific means or method that improves the 3 relevant technology or are instead directed to a result or effect that itself is the abstract idea and 4 merely invoke generic processes and machinery.” Free Stream Media Corp. v. Alphonso Inc., 996 5 F.3d 1355, 1363 (Fed. Cir. 2021) (cleaned up). Accordingly, “a claim is ineligible if it fails to 6 recite a practical way of applying an underlying idea and instead is drafted in such a result- 7 oriented way that it amounts to encompassing ‘the principle in the abstract’ no matter how 8 implemented.” Id. (cleaned up). Here, claim 14 recites no practical way of applying the 9 underlying idea of delivering and deriving a decryption key from a stream of data. Instead, claim 10 14 merely recites using generic computer components (a “host device,” a “storage device,” and a 11 “network,”) performing conventional computer processes (“receiving,” “deriving,” “decrypting,”) 12 to accomplish a desired result (“activation of local content”), without any practical detail (e.g., 13 how the decryption key is “delivered” or “derived” from the stream of data). This is precisely the 14 kind of claim language that the Federal Circuit rejected as patent ineligible in Free Stream. Id.; 15 see also Two-Way Media Ltd. v. Comcast Cable Commc’ns, LLC, 874 F.3d 1329, 1337 (Fed. Cir. 16 2017) (“The claim requires the functional results of ‘converting,’ ‘routing,’ ‘controlling,’ 17 ‘monitoring,’ and ‘accumulating records,’ but does not sufficiently describe how to achieve these 18 results in a non-abstract way.”). 19 Plaintiffs’ citation to TecSec only serves to underscore this conclusion. In TecSec, the 20 patent at issue was directed to a system and method of multi-level multimedia security in a data 21 network. There, the Federal Circuit found that the asserted claims were not abstract because the 22 claims described a specific method of managing access to objects using multiple levels of 23 encryption, which involved several specific steps including “accessing an ‘object-oriented key 24 manager’ and specified uses of a ‘label’ as well as encryption for the access management.” 978 25 F.3d at 1295. The court reasoned that these highly specific steps, in conjunction with the patent 26 specification and file history, demonstrated that the patent was directed to an inventive solution 27 specific to computer data networks. Id. 28 In contrast, here the ’834 patent more resembles the patent at issue in Free Stream, which 6 United States District Court Northern District of California 1 was directed to a system for targeted mobile advertising based on a consumer’s television viewing 2 patterns. There, the patentee argued that the patented invention was an advance over prior art by 3 “allow[ing] devices on the same network to communicate where such devices were previously 4 unable to do so.” Free Stream, 996 F.3d at 1363. However, the Federal Circuit found that this 5 was insufficient, because “[t]he asserted claims provide for how that is achieved only by stating 6 that the mechanism used to achieve this communication is by piercing or otherwise overcoming a 7 mobile device's security sandbox [and] . . . . do not describe at all how that result is achieved.” Id. 8 at 1363–64. Similarly, here Plaintiffs assert that their invention is directed to an unconventional 9 way of delivering and deriving decryption keys, but the asserted claims provide for that only by 10 stating that the delivery key is delivered via a “stream of data from the network” and do not 11 describe at all how that result is achieved. As did the patentee in Free Stream, Plaintiffs here argue that such methods are described in 12 13 detail in the specification, but those arguments are unavailing for the same reasons as in that case. 14 There, the Federal Circuit found that “[e]ven assuming the specification discloses how the 15 sandbox is overcome, the asserted claims nonetheless do not recite an improvement in computer 16 functionality” because none of the mechanisms disclosed in the specification were recited in the 17 claims. Id. at 1364. Here too, even assuming the specification discloses specific methods of 18 delivering and deriving a decryption key from a stream of data, “the asserted claims do not 19 incorporate any such methods” of doing so. Id. The absence of such details from the claim 20 language militates against patent eligibility. See also Yu, 1 F.4th 1044–45 (“In these 21 circumstances, the mismatch between the specification statements that [the patentee] points to and 22 the breadth of claim 1 underscores that the focus of the claimed advance is the abstract idea and 23 not the particular configuration discussed in the specification that allegedly departs from the prior 24 art.”). 25 Another “telltale sign of abstraction is when the claimed functions are mental processes 26 that can be performed in the human mind or using a pencil and paper.” Trinity, 72 F.4th at 1361– 27 62 (cleaned up); see also OpenTV, Inc. v. Apple, Inc., 2015 WL 1535328, at *4 (N.D. Cal. Apr. 6, 28 2015). Here too, this inquiry confirms that the claims are directed to an abstract idea. Claim 14’s 7 United States District Court Northern District of California 1 steps, once abstracted away from the generic computer and networking components involved, are 2 all steps that can be performed by a human mind or by a human using a pen and paper. As a 3 simple example, imagine the following: a human operating a telegraph machine is in possession of 4 a letter (local content) that is encrypted using a cypher. In order to decrypt the letter, she receives 5 a telegraph transmission (stream of data received over a network) that contains information as to 6 what the decryption key for the cypher is. Based on this information, she “derives” the decryption 7 key from the telegraph transmission and uses that decryption key to decrypt the letter. On its face, 8 claim 14 of the ’834 patent is nothing more than applying this age-old idea to the context of 9 modern content delivery systems, by using generic computer components and conventional 10 computer processes. This is an abstract idea. See Simio, LLC v. FlexSim Software Prod., Inc., 983 11 F.3d 1353, 1360 (Fed. Cir. 2020) (“Simply applying the already-widespread practice of using 12 graphics instead of programming to the environment of object-oriented simulations is no more 13 than an abstract idea.”). Similarly, the Federal Circuit has repeatedly recognized that claims 14 directed to the collection, organization, and transmission of data are “within the realm of abstract 15 ideas.” Elec. Power Grp., LLC v. Alstom S.A., 830 F.3d 1350, 1353 (Fed. Cir. 2016) (collecting 16 cases). Here, the data that is being transmitted just so happens to contain a decryption key, but 17 that is insufficient to render the claim non-abstract. 18 19 20 For these reasons, the Court finds that, at Alice step one, claim 14 of the ’834 patent is directed to a patent-ineligible abstract idea. ii. Alice Step Two 21 Turning to step two of the Alice inquiry, the Court considers “whether the claimed 22 elements— ‘individually and as an ordered combination’—recite an inventive concept.” Cellspin 23 Soft, Inc. v. Fitbit, Inc., 927 F.3d 1306, 1316 (Fed. Cir. 2019) (quoting Alice, 573 U.S. at 217). 24 Here, the Court finds that, as alleged, the ’834 patent does not recite an inventive concept 25 sufficient to elevate the claims beyond a mere abstract idea. 26 Plaintiffs do not appear to dispute that, taken individually, the elements claimed in the ’834 27 patent recite generic computer components and conventional computer processes. See Opp. at 13 28 (“Using known components in such a manner is sufficient to render the claims non-abstract.”). 8 1 Rather, Plaintiffs argue that, as an ordered combination, “the inventive concept of claim 14, as 2 confirmed by the specification, is the use of streaming data in an unconventional, advantageous 3 way, to convey decryption keys.” Id. In support, Plaintiffs rely on statements made in the 4 specification, and in the prosecution history, that the ’834 patent is unconventional and provides 5 an advantage over the prior art. For example, Plaintiffs argue that the ’834 patent is an inventive 6 improvement to existing content delivery systems, by providing for a “‘best of both worlds’ 7 solution that offers the advantages of streaming services . . . without the associated network and 8 bandwidth limitations; thus, allowing a higher-quality version of the content to be enjoyed.” Id. at 9 2–3, see also,’834 patent, 2:46–58. United States District Court Northern District of California 10 However, the Court is unconvinced. First, a critical problem with Plaintiffs’ argument is 11 that this alleged improvement is untethered to the actual language of claim 14, which on its face, is 12 so broad as to cover any method of decryption of local content where the decryption key is 13 delivered through, and derived from, “a stream of data [received] from a network.” Nothing in the 14 plain language of claim 14 requires that, for example, the encrypted content stored on the storage 15 device be a local copy of some content that is available from a streaming server, or that the 16 “stream of data from a network” be received from the same server as the server that also streams a 17 version of the encrypted local content. The term “streaming server” is not even present in the 18 claim language. Second, Plaintiffs’ reliance on statements included in the specification and made 19 during prosecution confuses an inventive concept with novelty, which does not transform an 20 abstract idea into a patent-eligible invention. See, e.g., SAP Am., Inc. v. InvestPic, LLC, 898 F.3d 21 1161, 1163 (Fed. Cir. 2018) (“We may assume that the techniques claimed are groundbreaking, 22 innovative, or even brilliant, but that is not enough for eligibility.”); Ultramercial, Inc. v. Hulu, 23 LLC, 772 F.3d 709, 715 (Fed. Cir. 2014) (“We do not agree . . . that the addition of merely novel 24 or non-routine components to the claimed idea necessarily turns an abstraction into something 25 concrete.”). Finally, even crediting Plaintiffs’ arguments as true, the “key inventive concept” that 26 Plaintiffs rely upon is precisely the idea that the Court found abstract at Alice step one: the 27 delivery and derivation of a decryption key from a stream of data. Because the “key inventive 28 concept” is itself abstract, the Court concludes that the ’834 patent fails to recite an inventive 9 United States District Court Northern District of California 1 concept “sufficient to ensure that the claim amounts to ‘significantly more’ than the abstract idea 2 itself.” Content Extraction, 776 F.3d at 1347 (quotation omitted). 3 Finally, Plaintiffs argue that it is premature for the Court to determine patent eligibility at 4 this stage in the proceedings because of unresolved fact and expert issues, including construction 5 of the claim language. See Opp. at 14–15. The Court disagrees. As discussed above, the Court 6 does not find Plaintiffs’ arguments relying on the patent specification and file history to be 7 persuasive. As to any potential claim construction issues, Plaintiffs have failed to propose any 8 constructions or explain why they would be relevant to the Court’s patent eligibility analysis. See 9 Opp. at 10, n.7 (arguing that the Court “must adopt Plaintiffs’ constructions” but failing to propose 10 any specific constructions or identify any concrete claim construction disputes). Absent any such 11 proposal, the Court declines to speculate and concludes that under a plain and ordinary reading of 12 the claims, the ’834 patent is directed to a patent-ineligible abstract idea and contains no inventive 13 concept. See Trinity, 72 F.4th at 1360–61 (to avoid a dismissal under § 101, a “patentee must 14 propose a specific claim construction or identify specific facts that need development and explain 15 why those circumstances must be resolved before the scope of the claims can be understood for § 16 101 purposes.”). However, in light of these arguments, the Court also cannot conclude at this 17 stage that further amendment necessarily would be futile. Therefore, the Court declines 18 Defendant’s request for dismissal with prejudice, and grants Plaintiffs a further opportunity to 19 amend Count Three. 20 IV. CONCLUSION 21 The Court GRANTS Defendant’s motion to dismiss Count Three of the Amended 22 Complaint with leave to amend. Any Second Amended Complaint must be filed within 21 days of 23 the date of this order. Failure to remedy the deficiencies described in this order will result in 24 dismissal with prejudice and without further leave to amend. 25 26 27 28 IT IS SO ORDERED.
