1 HONORABLE RICHARD A. JONES 2 3 4 5 6 7 UNITED STATES DISTRICT COURT 8 WESTERN DISTRICT OF WASHINGTON 9 AT SEATTLE 10 11 TREEHOUSE AVATAR LLC, CASE NO. C17-1860-RAJ 12 Plaintiff, 13 ORDER ON CLAIM v. CONSTRUCTION 14 VALVE CORPORATION, 15 16 Defendant. 17 18 This matter comes before the Court on the parties’ request for claim 19 construction. Dkt. # 139. 20 I. BACKGROUND 21 Plaintiff Treehouse Avatar LLC (“Plaintiff” or “Treehouse”) brings suit against 22 Defendant Valve Corporation (“Defendant” or “Valve”) for infringing its patent, 23 United States Patent No. 8,180,858 (“the ‘858 patent”). The ‘858 patent, issued on 24 May 15, 2012, relates to methods of collecting data from an information network in 25 response to user choices of a plurality of users navigating character-enabled (“CE”) 26 network sites on the network. Dkt. # 1-1. 27 1 Treehouse initially brought this patent infringement action against Defendant 2 Valve Corporation (“Defendant” or “Valve”) in Delaware in 2015. Dkt. # 15. In 3 December 2017, the case was transferred to this District. Dkt. # 116. 4 The parties initially filed their claim construction briefing in Delaware and 5 disputed thirty terms. See Dkt. ## 58, 63, 66, 69. After the case was transferred to this 6 Court, the parties requested, and were granted, leave to file a joint claim construction 7 briefing, consolidating the initial briefing and reducing the number of terms in dispute. 8 Dkt. # 128. The parties now ask the Court to construe ten disputed claim terms. Dkt. 9 # 139. 10 The court held a Markman hearing in this matter on November 8, 2019. Dkt. # 11 153. 12 II. LEGAL STANDARD 13 Claim construction is a matter of law. See Markman v. Westview Instruments, 14 Inc., 517 U.S. 370, 372 (1996). The specification of a patent begins with a written 15 description, which often includes drawings or illustrations, and “conclude[s] with one 16 or more claims particularly pointing out and distinctly claiming the subject matter 17 which the inventor . . . regards as the invention.” 35 U.S.C. § 112(b). The claims 18 reign supreme over the remainder of a patent; they alone “define the scope of patent 19 protection.” Johnson & Johnston Assocs. Inc. v. R.E. Serv. Co., 285 F.3d 1046, 1052 20 (Fed. Cir. 2002) (“[A] patent applicant defines his invention in the claims, not in the 21 [remainder of] the specification.”); Corning Glass Works v. Sumitomo Elec. U.S.A., 22 Inc., 868 F.2d 1251, 1257-58 (Fed. Cir. 1989) (“A claim in a patent provides the metes 23 and bounds of the right which the patent confers on the patentee to exclude others 24 from making, using, or selling the protected invention.”). 25 Although the claims alone define the scope of the invention, construing the 26 claims requires the Court to start with the language of the claims and also to look 27 elsewhere. The Federal Circuit’s en banc decision in Phillips v. AWH Corp., 415 F.3d 1 1303 (Fed. Cir. 2005) provides comprehensive instructions for navigating evidence 2 relevant to claim construction. The court begins with the language of the claims 3 themselves, which “provide substantial guidance as to the meaning of particular claim 4 terms.” Id. at 1314; Amgen Inc. v. Hoechst Marion Roussell, Inc., 457 F.3d 1293, 5 1301 (Fed. Cir. 2006) (citing Phillips for the proposition that “claim construction must 6 begin with the words of the claims themselves”). The Court should “generally give[] 7 [claim terms] their ordinary and customary meaning” in the eyes of a person of 8 ordinary skill in the art as of the filing date of the patent. Phillips, 415 F.3d at 1312-13 9 (quoting Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed Cir. 1996)). 10 In some cases, the ordinary meaning “may be readily apparent even to lay judges,” in 11 which case the claim construction “involves little more than the application of the 12 widely accepted meaning of commonly understood words.” Id. at 1314. 13 Beyond the claim language, the remainder of the specification is “always highly 14 relevant to the claim construction analysis.” Id. at 1315 (quoting Vitronics, 90 F.3d at 15 1582). The specification is dispositive when the inventor uses it to explicitly define a 16 claim term, in which case “the inventor’s lexicography governs.” Id. at 1316. But 17 even where the specification does not explicitly define a term, it may do so implicitly 18 (Id. at 1321) and in any event is a “concordance for the claims” (Id. at 1315 (citation 19 omitted)) on which the Court should “rely heavily.” Id. at 1317. At the same time, a 20 court must toe a fine line “between using the specification to interpret the meaning of a 21 claim and importing limitations from the specification into the claim.” Id. at 1323; see 22 also SciMed Life Sys., Inc. v. Advanced Cardiovascular Sys., Inc., 242 F.3d 1337, 23 1340 (Fed. Cir. 2001) (describing “reading a limitation from the written description 24 into the claims” as “one of the cardinal sins of patent law”). 25 The final source of “intrinsic evidence” bearing on claim interpretation is the 26 patent’s prosecution history. Phillips, 415 F.3d at 1317. The prosecution history 27 begins with the inventor’s application to the USPTO and includes all communication 1 between the inventor and the USPTO, culminating in the USPTO’s decision to issue 2 the patent. Vitronics, 90 F.3d at 1582. An inventor must often disclaim part of the 3 scope of an invention during prosecution to obtain a patent. Where the prosecution 4 history reflects a “clear and unmistakable disavowal of scope,” a court must construe 5 the claims accordingly. Purdue Pharma L.P. v. Endo Pharms., Inc., 438 F.3d 1123, 6 1136 (Fed. Cir. 2006). The court must recognize, however, that “the prosecution 7 history represents an ongoing negotiation between the PTO and the applicant,” and 8 thus “often lacks the clarity of the specification.” Phillips, 415 F.3d at 1317. It is 9 nonetheless useful for claim construction, although less so than the specification. Id. 10 Extrinsic evidence is always “less significant” and in general “less reliable” 11 than intrinsic evidence. Id. at 1318. Unlike intrinsic evidence, extrinsic evidence is 12 not “created at the time of patent prosecution for the purpose of explaining the patent’s 13 scope and meaning.” Id. The court has discretion to use extrinsic evidence in claim 14 construction, but need not do so. Id. at 1319. Indeed, where the intrinsic evidence is 15 adequate to define a claim term, “it is improper to rely on extrinsic evidence.” 16 Vitronics, 90 F.3d at 1583; Trilogy Commc’ns, Inc. v. Times Fiber Commc’ns, Inc., 17 109 F.3d 739, 744 (Fed. Cir. 1997) (“When . . . district court has concluded that the 18 patent specification and prosecution history adequately elucidate the proper meaning 19 of claims, expert testimony is not necessary and certainly not crucial.” 20 III. DISCUSSION 21 A. Disputed Claim Terms 22 The parties dispute the meaning of ten separate terms in the ‘858 Patent. 23 1.

Cir. 1997) (“When . . . district court has concluded that the 18 patent specification and prosecution history adequately elucidate the proper meaning 19 of claims, expert testimony is not necessary and certainly not crucial.” 20 III. DISCUSSION 21 A. Disputed Claim Terms 22 The parties dispute the meaning of ten separate terms in the ‘858 Patent. 23 1. “Character” 24 Plaintiff’s Defendant’s Court’s Construction Construction Construction 25 No construction “character, object, or “character, object, or 26 required scene” scene” 27 1 The claim term “character” is used in claims 1-4, 6, and 21-23. For example, as 2 used in claim 1 of the ‘858 patent: “storing a plurality of character data in a database 3 accessible by said CE network site.” In the initial claim construction briefing, the 4 parties agreed that the term “character” should be construed as “character, object, or 5 scene.” Dkt. # 58 at 5, Dkt. # 63 at 11-12. Treehouse now contends that no 6 construction is necessary. Dkt. # 139 at 8. 7 Valve argues that construction is necessary because the ordinary meaning of the 8 term “character” is substantially narrower than the meaning within the patent. The 9 intrinsic evidence supports Valve’s construction. First, the patent specification clearly 10 expands the definition of “character” to include an “object” or “scene.” Dkt. # 1-1 11 (‘858 patent, Col. 1:32-35). In addition, this meaning was adopted by the Patent Trial 12 and Appeal Board (“PTAB”) in the now-concluded Inter Partes Review proceeding. 13 Dkt. # 62 (Joint Appendix for Claim Construction Briefing), A377 & A380, PTAB 14 Institution Decision, at 8 & 11. 15 Therefore, “character” is defined as: “character, object, or scene.” 16 2. “Character attribute” 17 Plaintiff’s Defendant’s Court’s Construction Construction Construction 18 No construction “quality or characteristic “quality or characteristic 19 required inherent or ascribed to a inherent or ascribed to a character, object, or character, object, or 20 scene” scene” 21 The term “character attribute” is used in claims 1 and 4. Treehouse argues that 22 “character attribute” does not require construction, for the same reason that the term 23 “character” does not need to be construed. Dkt. # 139 at 10. Valve again argues that 24 construction is necessary because the ordinary meaning of the term is considerably 25 narrower than the meaning in the context of the ‘858 patent. Dkt. # 139 at 10. 26 Valve’s construction is supported by the specification, as discussed above, and 27 1 was also adopted by the PTAB in the Inter Partes Review proceeding. JA A377 & 2 A380, PTAB Institution Decision, at 8 & 11. Accordingly, the Court adopts Valve’s 3 construction. 4 The term “character attribute” is defined as: “quality or characteristic inherent 5 or ascribed to a character, object, or scene.” 6 3. “Present[ing] … to a/[the] user interface” 7 Plaintiff’s Defendant’s Court’s Construction Construction Construction 8 “providing to a/ “display[ing] and/or Plain and ordinary 9 [the] user generate[ing] sound on a / meaning controls interface” [the] user device” 10 The term “present[ing] … to a/[the] user interface” appears in claims 1 and 4. 11 For example, claim 1 specifies: “presenting to a user interface, one or more character 12 data defining one or more characters.” Construction of this term depends on the scope 13 of “presenting.” Treehouse argues that “providing” is the appropriate construction 14 because it allows for both “characters/attributes” and “data” to be presented to the 15 user. Dkt. # 139 at 11. At the Markman hearing, Treehouse later conceded that the 16 term does not require construction. Dkt. # 154 (Markman Hearing Court Transcript) at 17 2:20-25. 18 Valve, for its part, seeks to import additional limitations on the scope of the 19 term by replacing “presenting” with “display[ing] and/or generate[ing]\ sound” and 20 replacing “user interface” with “user device.” Dkt. # 139 at 12. Valve argues that this 21 construction is necessary because the only way for a user to select a character attribute 22 is to “visually see it or hear an audio presentation of it.” Dkt. # 139 at 13. 23 The Court agrees with Valve that replacing “presenting” with “providing” is 24 unnecessary and potentially confusing. The term “presenting” is used repeatedly 25 throughout the specification, including in the context of presenting data: “[i]n a second 26 aspect, the invention relates to an apparatus for presenting data to a network user based 27 1 on choices made by the user while within a character-enabled network site.” Col. 2 3:38-40. The claims also refer to presenting both characters or attributes as well as 3 data. As such, it is unnecessary to adopt “providing” in order to clarify that both 4 characters/attributes and data are being presented to the user. 5 However, the Court also finds no basis to impose the additional limitations 6 described in Valve’s proposed construction. A PHOSITA reviewing the claims and 7 specification would understand the scope of the invention without adding Valve’s 8 proposed limitations. Hill-Rom Servs. v. Stryker Corp., 755 F.3d 1367, 1374 (Fed. 9 Cir. 2014) (“Claim terms should be given their plain and ordinary meaning to one of 10 skill in the art at the relevant time and cannot be rewritten by the courts to save their 11 validity.”). As a result, the plain and ordinary meaning of the term controls. 12 No claim construction is necessary here. 13 4. “Real-time / Real Time” 14 Plaintiff’s Defendant’s Court’s Construction Construction Construction 15 “without any lag Indefinite “without any lag 16 perceived by a user” perceived by a user” 17 The term “real time” appears in claims 1, 15, and 18. In claim 1, for example, 18 the patent specifies: “upon selection of a character attribute by the user, presenting in 19 real time to the user interface, the selected character including the selected character 20 attribute . . . .” 21 Treehouse argues that this term does not require construction, but in the event 22 that the Court determines that the term should be construed, proposes the construction 23 “without any lag perceived by a user.” Dkt. # 139 at 17. Valve argues that “real time” 24 is indefinite because a PHOSITA would not understand the outer limits of the term 25 (i.e. how much delay would cause a presentation to be deemed not real time). Dkt. # 26 139 at 19-20. 27 1 A patent is impermissibly indefinite if its claims, read in light of the 2 specification and prosecution history, fail to inform with reasonable certainty, a person 3 skilled in the art as to the scope of the claimed invention. Nautilus, Inc. v. Biosig 4 Instruments, Inc., 134 S. Ct. 2120, 2124 (2014). The claim language must be “precise 5 enough to afford clear notice of what is claimed, thereby apprising the public of what 6 is still open to them.” Id. (internal quotations omitted). 7 Here, neither the specification nor the patent prosecution history is useful in 8 defining this term. Since the intrinsic evidence does not provide meaningful guidance 9 as to the proper construction of the term, the Court must look to extrinsic evidence. 10 Treehouse points to the dictionary definition which defines “real time” as “the actual 11 time during which something takes place.” Dkt. # 139 at 17. According to Treehouse, 12 the meaning of “real time” depends on context, in this case “presenting in real time to 13 the user interface.” Id. Treehouse’s expert notes that in the context of the patent, as 14 long as a user does not perceive any lag in the system’s response to the user’s activities 15 (e.g., presentation of the shirt style after “rolling over” a brand) a PHOSITA would 16 understand it to be happening in real-time. Dkt. # 139 at 18 (citing Dkt. # 59 17 (Sacerdoti Decl.) at ¶ 14). 18 Valve’s expert argues that the term is impermissibly indefinite because the 19 “amount of lag that is perceptible to the user is an inconsistent, subjective, and 20 unreliable metric, which depends upon many factors and varies from user to user.” 21 Dkt. # 65 (Zyda Decl.) at ¶ 17. For example, Valve notes that in the context of 22 networked virtual worlds or three-dimensional computer games “a graphics update rate 23 of 10 frames per second” would have been considered real-time in 1995 while “20 24 frames per second would have been required to qualify as ‘real time’ in 2000.”1 Id. 25
26 1 At oral argument, Defendants introduced additional supplemental authority which 27 was not included in the briefings. See HZNP Medicines LLC v. Actavis Labs. UT, Inc., 1 The Court finds that the term “real time” is not indefinite. Valve’s suggestion 2 that the patent must describe the precise amount of delay (down to the number of 3 frames per second) in order for the claim to be definite is incorrect. See Nautilus, Inc. 4 v. Biosig Instruments, Inc., 572 U.S. 898, 899 (2014) (“The standard adopted here 5 mandates clarity, while recognizing that absolute precision is unattainable.”). Valve 6 imposes a more demanding standard than is required by law. Sonix Tech. Co. v. 7 Publications Int’l, Ltd., 844 F.3d 1370, 1377 (Fed. Cir. 2017) (“Thus, a patentee need 8 not define his invention with mathematical precision in order to comply with the 9 definiteness requirement.”) (citations and internal quotation marks omitted)). Here, a 10 person of ordinary skill in the art would understand that a presentation is in “real time” 11 if the user does not perceive a lag in the display. 12 Therefore, “real time” is defined as: “without any lag perceived by the user.” 13 5. “Tallying…by a plurality of users” 14 Plaintiff’s Defendant’s Court’s Construction Construction Construction 15 “counting or “counting or calculating a “counting or calculating a 16 calculating a total total number of times the total number of times the number of times selected character attribute selected character attribute 17 the selected has been selected by a has been selected by a 18 character attribute plurality of users” plurality of users” has been selected, 19 aggregated across 20 a plurality of users” 21 The term “[t]allying … by a plurality of users” is used in claims 1 and 15 of the 22 ‘858 patent. For example, claim 1 specifies: “tallying the number of times the selected 23 character attribute has been selected by a plurality of users.” The parties agree on the 24
25 26 940 F.3d 680 (Fed. Cir. 2019); see also Dkt. # 154 (Markman Hearing Court Transcript) at 8:1-9:15. The Court has reviewed the Federal Circuit’s opinion in 27 HZNP Medicines and finds it is distinguishable from this case. 1 construction of “tallying” as “counting or calculating a total.” Thus, the only dispute 2 relates to “a plurality of users.” Treehouse argues that the specification clearly 3 supports replacing “by” with “aggregated across” because the purpose of the invention 4 is to determine “market trends” and “demographics” and this data is not useful unless 5 it is aggregated. Dkt. # 139 at 23. 6 Valve argues that tallying across a plurality of users could encompass several 7 different options including tallying the number of times a character attribute is selected 8 by two or more users or tallying the number of times a character attribute is selected 9 by two or more users and aggregating the total. Dkt. # 139 at 24. The Court agrees. 10 A person of ordinary skill in the art would understand “tallying . . . by a plurality of 11 users” to include aggregation. But, nothing in the claims or specification expressly 12 limits the scope of the claims to aggregation and the Court will not import this 13 limitation on its own. Epistar Corp. v. ITC, 566 F.3d 1321, 1335 (Fed. Cir. 2009) 14 (“[d]disavowal requires expressions of manifest exclusion or restriction, representing a 15 clear disavowal of claim scope.”). Accordingly, the Court adopts Valve’s 16 construction. 17 The term “tallying . . . by a plurality of users” is defined as: “counting or 18 calculating a total number of times the selected character attribute has been selected by 19 a plurality of users.” 20 6. “Character persona data” 21 Plaintiff’s Defendant’s Court’s Construction Construction Construction 22 “data related to “data indicative of a “data indicative of a 23 personality of a collection of attributes and collection of attributes and character derived actions ascribed to a actions ascribed to a 24 from the character” character” 25 collection of attributes and 26 actions ascribed to a character” 27 1 The term “character persona data” is used in claims 4−7 of the patent. For 2 example, claim 5 specifies: “[t]he method of claim 4 wherein the character-persona 3 data is different from the character data and the character-attribute data.” At oral 4 argument, the parties agreed to adopt Valve’s construction of the term “character 5 personal data.” Dkt. # 154 at 10:2-16. This construction is supported by the claim 6 language and specification. Accordingly, the Court adopts Valve’s construction. 7 The term “character persona data” is defined as: “data indicative of a collection 8 of attributes and actions ascribed to a character.” 9 7. “Data comprises … presentations” 10 Plaintiff’s Defendant’s Court’s Construction Construction Construction 11 “character- Indefinite Plain and ordinary 12 persona data meaning controls comprises at least 13 one of data 14 defining audio presentations and 15 data defining visual image 16 presentations” 17 The term “data comprises . . . presentations” is used in claim 6 of the patent. 18 Claim 6 specifies: “[t]he method of character-persona data comprises at least one of 19 audio presentations and visual image presentations.” Treehouse argues this term does 20 not require construction, but to the extent the Court believes that it does, Treehouse 21 proposes adding “data defining” to further illustrate that the claim is referring to the 22 underlying data defining the audio and visual presentations. Dkt. # 139 at 34. Valve 23 contends that this term is impermissibly indefinite because Treehouse’s proposed 24 construction requires the Court to rewrite the claim by adding in the term “data 25 defining” in two places. Dkt. # 139 at 35. 26 27 1 This term is not indefinite. However, the Court agrees that Treehouse’s 2 proposed construction is confusing and unnecessary. Here, a PHOSITA reviewing the 3 claims and specification would understand the scope of the invention without adding 4 Treehouse’s proposed limitation. For example, the specification explains that a 5 “character has a plurality of attributes, each defined by at least one of either audio data 6 and/or visual image data. The plurality of attributes collectively defines a character 7 persona.” See Col. 3:57-63. The specification also refers to audio/visual data and 8 audio/visual presentations interchangeably. For example, “[t]hese site programs 9 operate in conjunction with various stored audio data/presentations and visual image 10 data/presentations to provide the presentations to the user interface.” Col. 4:49-53 11 (emphasis added). As such, there is no need to add “data defining” to clarify that the 12 claim is referring to the underlying data defining the “audio presentations and visual 13 image presentations.” Instead, the ordinary meaning of this term controls. 14 No claim construction is necessary here. 15 8. “Accessible to said CE network site” 16 Plaintiff’s Defendant’s Court’s Construction Construction Construction 17 “accessible to said Indefinite “accessible to said 18 plurality of CE network plurality of CE network sites” sites” 19 20 Terms 8 and 9 are part of the same claim (21) and were briefed together by the 21 parties. Accordingly, the Court will analyze them together below. 22 // 23 // 24 // 25 26 // 27 1 9. “Causing said character to be displayed on said CE network site on said device of said user” 2 Plaintiff’s Construction Defendant’s Court’s Construction Construction 3 4 “causing said character Indefinite “causing said character to to be displayed by said be displayed by said one 5 one of said plurality of of said plurality of CE 6 CE network sites on said network sites on said device of said user” device of said user” 7 8 The terms “accessible to said CE network site” and “causing said character to 9 be displayed on said CE network site on said device of said user” appear in claim 21. 10 For example, claim 21(c) explains: “storing said associating information and said 11 character profile in a database that is accessible to said CE network site.” Later, claim 12 21(e) provides: “if said user has previously created a character profile, retrieving said 13 character profile from said database and causing said character to be displayed on said 14 CE network site on said device of said user . . . .” Id. (emphasis added). 15 Treehouse argues that the terms, as written, contain drafting errors that are 16 easily remedied by making minor adjustments to the disputed terms. Dkt. # 139 at 37- 17 38. According to Treehouse, the claim’s preamble illustrates this. Id. at 37. The 18 preamble of claim 21 describes: “A method of operating a plurality of character 19 enabled (CE) network sites for a plurality of users . . . .” Treehouse argues that the 20 preamble’s reference to a plurality of CE network sites, suggests that the remaining 21 steps of the claim were also intended to refer to a plurality of CE network sites. Dkt. # 22 139 at 37-38. 23 Valve objects to Treehouse’s characterization, arguing that Treehouse is asking 24 the Court to make “material changes” to the claim, which as currently written is 25 indefinite. Dkt. # 139 at 39-40. First, Valve notes that there is a “substantial 26 difference” between the use of the singular tense and the plural tense in the claims. 27 Dkt. # 139 at 40. For example, claim 21(a) refers to creating a character for use on a 1 “plurality of CE network sites” while claim 21(d) refers to receiving a request for 2 access to only “one of said plurality of CE network sites.” Valve argues that 3 Treehouse is asking the Court to change the term in claim 21(c) from singular to 4 plural, but to change the term in claim 21(e) in such a way that it remains singular. 5 Dkt. # 139 at 40. According to Valve, claim 21(c) could just as easily be changed to 6 “one of said plurality of CE network sites” rather than “said plurality of CE network 7 sites” and the availability of this alternative renders the claim indefinite. Id. at 40-41. 8 “[I]n a patent infringement suit, a district court may correct an obvious error in 9 a patent claim.” CBT Flint Partners, LLC v. Return Path, Inc., 654 F.3d 1353, 1358 10 (Fed. Cir. 2011). However, a district court may correct a patent claim only if “(1) the 11 correction is not subject to reasonable debate based on consideration of the claim 12 language and the specification and (2) the prosecution history does not suggest a 13 different interpretation of the claims.” Novo Industries, L.P. v. Micro Molds Corp., 14 350 F.3d 1348, 1354 (Fed. Cir. 2003). “District courts may correct ‘obvious minor 15 typographical and clerical errors in patents,’ but ‘major errors are subject only to 16 correction by the PTO.’ ” Parallel Networks Licensing, LLC v. Int'l Bus. Machines 17 Corp., 83 F. Supp. 3d 571, 575 (D. Del. 2015) (quoting Novo, 350 F.3d at 1357). 18 “[A] district court must consider any proposed correction from the point of 19 view of one skilled in the art.” CBT Flint, 654 F.3d at 1358 (internal quotation marks 20 omitted). “Any correction of a claim has to be consistent with the invention described 21 in the specification and drawings of the original patent.” Id. at 1359 (internal 22 quotation marks omitted). “[T]he prosecution history should be consulted to ascertain 23 whether there is only a single reasonable construction.” Fargo Electronics, Inc. v. Iris, 24 Ltd., Inc., 287 Fed. Appx. 96, 101–02 (Fed. Cir. 2008). 25 Claim 21(c) describes the method of storing the character information in a 26 database accessible to “said CE network site.” Treehouse asks the Court to change 27 this to “said plurality of CE network sites” but Valve argues that this could also be 1 changed to read “one of said plurality of CE network sites.” The Court finds Valve’s 2 alternative construction unreasonable in light of the claim language and specification. 3 CBT Flint, 654 F.3d at 1358 (holding a district court may correct an obvious error in a 4 patent claim where the correction is not subject to reasonable debate based on 5 consideration of the claim language and specification). 6 Here, the preamble describes a method of operating a “plurality” of CE network 7 sites. Claim 21(a) describes the process of a user creating a character for use on the 8 plurality of CE network sites. Later, claim 21(d) contemplates a user retrieving a 9 previously created character profile from the database after “receiving a request for 10 access to one of a plurality of CE network sites.” This inherently requires that the 11 character information in the database be accessible to each of the plurality of CE 12 network sites. 13 The specification reinforces this interpretation of the claim, describing a 14 method of storing character information in a database (Col. 5:1-3; Col. 9:49-53) that is 15 accessible to multiple CE network sites. See Col. 11:39-41 (“In accordance with the 16 present invention, the character created by the user may be retrieved from the central 17 database 24 by the user through other C-E sites.”). There is also nothing in the 18 prosecution history to suggest an alternative interpretation. Fargo Electronics, Inc. v. 19 Iris, Ltd., Inc., 287 Fed. Appx. 96, 101–02 (Fed. Cir. 2008). Based on the claim 20 language and specification, a person of ordinary skill in the art would know that 21 “accessible to said CE network site” means “accessible to said plurality of CE network 22 sites.” CBT Flint, 654 F.3d at 1358 (“a district court must consider any proposed 23 correction ‘from the point of view of one skilled in the art.’”) (internal citation 24 omitted). 25 The same is true for the disputed term in claim 21(e). Claim 21(e) describes 26 retrieving the character profile for display on the requested site. The previous step, 27 claim 21(d), describes the process of receiving a request for access to “one of said 1 plurality of CE network sites.” So, it follows that the “said CE network site” in claim 2 21(e) is actually “one of said plurality of CE network sites” as described in claim 3 21(d). A person of ordinary skill in the art reviewing the claim language and the 4 specification would understand the scope and meaning of the term to be “causing said 5 character to be displayed by said one of said plurality of CE network sites on said 6 device of said user.” Accordingly, the Court adopts Treehouse’s proposed 7 construction for both terms. 8 The term “accessible to said CE network site” is defined as: “accessible to said 9 plurality of CE network sites.” The term “causing said character to be displayed on 10 said CE network site on said device of said user” is defined as: “causing said character 11 to be displayed by said one of said plurality of CE network sites on said device of said 12 user.” 10. “Automatically retrieved by said CE network site upon 13 entering said CE network site” 14 Plaintiff’s Defendant’s Court’s Construction Construction Construction 15 “automatically retrieved Indefinite “automatically retrieved 16 by said one of said by said one of said 17 plurality of CE network plurality of CE network sites upon the user sites upon the user 18 entering said one of said entering said one of said 19 plurality of CE network plurality of CE network sites” sites” 20 The term “automatically retrieved by said CE network site upon entering said 21 CE network site” appears in claim 23. Claim 23 specifies: “the method of claim 22 22 wherein said character profile is automatically retrieved by said CE network site upon 23 entering said CE network site.” 24 Claim 23 depends on claim 22, which depends on claim 21. As discussed 25 above, claim 21 describes a method of operating a “plurality” of CE network sites. 26 Treehouse argues that the term “said CE network site” in claim 23 should actually read 27 1 “one of said plurality of CE network sites” consistent with the preceding claim 2 language and the specification. Dkt. # 139 at 43-44. 3 Claim 21(e) describes a process of displaying a character on a CE network site. 4 The Court previously held that the single “said CE network site” referenced in claim 5 21(e) should be construed as “one of said plurality of CE network sites.” For the same 6 reason, claim 23, which describes the process of retrieving the character profile that is 7 later displayed in claim 21(e), should also be understood to refer to “one of said 8 plurality of CE network sites.” 9 Valve argues that this term is impermissibly indefinite because the patent fails 10 to disclose what is meant by “automatically retrieved … upon entering said CE 11 network site.” Dkt. # 139 at 45. For example, Valve argues that there are alternative 12 interpretations of the term “automatically retrieved” such as “upon a character 13 entering,” rather than “upon a user entering.” Id. In the context of the claims and 14 specification, however, the Court finds this a distinction without a difference. The 15 specification repeatedly discloses that a selected character is associated with a single 16 user. As such, Valve’s proposed construction does not alter the scope and meaning of 17 the term. CBT Flint, 654 F.3d at 1359 (holding district court had authority to correct 18 claim where claim had same scope and meaning under alternative meanings). 19 Accordingly, the Court adopts Treehouse’s construction. 20 The term “automatically retrieved by said CE network site upon entering said 21 CE network site” is defined as: “automatically retrieved by said one of said plurality of 22 CE network sites upon the user entering said one of said plurality of CE network 23 sites.” 24 IV. CONCLUSION 25 For the reasons stated above, the Court adopts the above constructions set forth 26 in this opinion for the disputed terms of the ‘858 patent. The parties are ordered that 27 1 they may not refer, directly or indirectly, to each other’s claim construction positions 2 in the presence of the jury. 3 4 Dated this 25th day of November, 2019. 5 A 6
