`INTRODUCTION
`Caravan’s patent describes a specific type of collapsible tent frame. The
`claimed frame requires a “center pole” that stretches and sustains the roof when a
`tent is pitched. The parties disagree on the proper meaning of the claimed center
`pole. In an attempt to broaden the reach of its patent, Caravan suggests a
`construction that replaces the specific structure claimed, “pole,” with a generic term,
`“element.” But the evidence does not support such an outcome. Nor does the
`evidence justify Caravan’s request that the Court decline to construe the remaining
`five disputed terms. Although the patented technology is simple, the disputed claim
`terms contain opaque language requiring the constructions Defendants propose or,
`for the final term, recite indefinite language.
`II. THE ’040 PATENT
`A. Relevant Disclosures from the Specification
`U.S. Patent No. 5,944,040 (the “’040 Patent”) is directed to a collapsible tent
`frame, such as those “capable of making, pitching or striking a tent easily and
`quickly when necessary and, more particularly to a collapsible tent frame suitable
`for giving an enlarged and heightened interior space to users when pitching a tent.”
`Dkt. 1-1 (’040 Patent), 1:4-10. It issued on August 31, 1999, from an application
`filed on May 21, 1998. The patent expired on May 21, 2018.
`The ’040 Patent acknowledges that collapsible tent frames were well-known
`in the prior art. Indeed, the admitted prior art (shown in Figures 1 and 2) contains
`most of the components recited in the three asserted claims. The ’040 Patent
`explains that known tent frames could “be easily and quickly pitched or struck when
`necessary”—where pitch means to raise the tent, and strike means to lower it—and
`were “preferably designed for being collapsible.” Id., 1:15-22.

`
`The prior art figures above confirm that these known frames had four side
`poles (Element 1) connected to each other by side pole ribs (Element 2, depicting
`scissor assemblies). Id., 1:23-29, Figs. 1, 2. Upper ends of the side pole ribs are
`hinged to the tops of the side poles. Lower ends of the side pole ribs are hinged to
`sliders (Element 7) moveably fitted over the side poles. Id., 1:32-35. Movement of
`the side poles towards the center of the frame causes the sliders to move down the
`side poles, which folds the side pole ribs, leading to closure of the tent. Id., 1:34-37.
`To support the top of the tent, the prior art collapsible tent frame also included
`four center pole ribs (identified as Element 3 scissor assemblies), with outer ends
`coupled to the joints in each side pole rib and inner ends coupled to a center pole,
`identified as Element 6. See, e.g., id., 1:39-43 & Fig. 1.

`’040 Patent, Figure 1 (Prior Art)
`
`
`
`The patent identifies problems with prior art collapsible tent frames. These
`include limited headspace because the center pole ribs extend horizontally across the
`frame, thereby requiring users to be careful not to hit their heads when inside the
`tent. Id., 1:54-64. Other problems included complex construction of the center
`pole’s slide guider (Element 5) and the heavy weight of the frame. Id., 1:65-2:2.
`To solve these problems, the ’040 Patent describes as “the present invention”
`a collapsible tent frame in “which the center pole is coupled to the side poles, thus
`giving an enlarged and heightened interior space to users when pitching a tent and
`allowing a user to easily handle the frame when pitching or striking the tent.” Id.,
`2:5-12. Referring to Figures 3 and 4, the patent describes the center pole ribs 30
`connecting the center pole 50 directly to the side poles 10 at the corners of the
`frame, rather than the prior art construction connecting the center pole ribs at the
`center of the side pole ribs. Id., 2:64-66.
`The center pole ribs include two rib members joined together by a hinge 30a
`that bends when the tent is raised/lowered. Id., 2:66-3:4, 3:23-27. The outside rib
`member is “coupled to the sliders 70” on the side poles 10 “through support links
`40.” Id., 2:66-3:1. When pitching the tent, the support links 40 function to fully
`stretch the center pole ribs 30 and the side pole ribs 20. Id., 3:14-28. When striking

`the tent, the support links 40 pull the center pole ribs 30 downwardly, thereby
`folding the center pole ribs 30 at the hinge joint 30a and moving the center pole 50
`downwardly. Id., 3:38-45. The ’040 Patent describes “center pole 50” as “having a
`simple construction,” rather than the “complex construction” of prior art center
`pole 6 that included a slide guider and connector. Id., 2:64, 65, & 1:65-67.
`
`
`The ’040 Patent Figure 3
`
`
`
`
`
`To address the problems of limited head space, heavy weight of the frame,
`and complex construction, the applicant removed extraneous pieces from the tent
`frame. The applicant removed the portion of the scissor-style center pole ribs of the
`prior art that connected the center of the scissor assembly to the slide guider. The
`scissor-style center pole ribs 3 of the prior art canopy were modified to include the
`support links 40 and remove the bottom scissor portion that connected to the slide
`guider of the center pole. Thus, only one connection point at top would be needed
`to connect the center pole ribs to the center pole.
`The slide guider 5 of the prior art has therefore been eliminated, allowing the
`center pole 6 to be shortened to the center pole 50 found in the representative
`embodiment. Essentially, a shorter center pole replaced the combination of the slide
`guider 5 and the center pole 6.

`
`B. Relevant Prosecution History
`The application that led to the ’040 Patent originally contained a single
`independent claim. In the first Non-Final Office Action, the Examiner rejected the
`single independent claim as anticipated by U.S. Patent No. 4,779,635 to Lynch. See
`Declaration of Dario Machleidt (“Machleidt Decl.”), at Ex. A (’040 Patent File
`History), at 52.1 In a response, the applicant amended claim 1 and also submitted
`new dependent claims 2 and 3. Id., at 59-60.
`The applicant also argued why Lynch did not anticipate the alleged invention.
`According to the applicant, Lynch’s “roof support member 40” does not disclose the
`claimed “center pole ribs.” Id., at 61. The applicant characterized Lynch’s “roof
`support member 40” as telescoping when the tent is struck, which was allegedly
`patentably distinct from a “center pole rib” that includes “two rib members coupled
`to each other through a hinge joint.” Id., at 61.
`C.
`Prior Litigation Involving the ’040 Patent
`Caravan asserted the ’040 Patent in a prior litigation in this district: Int’l E-Z
`Up, Inc., et al. v. Caravan Canopy Int’l, Inc., et al., No. 2:01-cv-06530 (C.D. Cal.
`July 30, 2001) (“E-Z Up Case”). In that case, International E-Z Up, Inc., James P.
`Lynch, and K.D. Kanopy, Inc. (collectively, the “E-Z Up Plaintiffs”) sued Caravan
`for infringement of an unrelated patent. Caravan counterclaimed against the E-Z Up

`Plaintiffs, alleging infringement of the ’040 Patent.
`During the Markman phase of that case, Caravan, as it does here, argued that
`“center pole” must mean “a centrally-disposed element for stretching and sustaining
`a tent’s roof.” See Ex. B (Caravan Opening Markman Br., E-Z Up Case), at 21.
`Caravan contended that the applicant acted as its own lexicographer by treating the
`claimed “center pole” as something other than a “pole.” Id. (Caravan alleging that
`it “is easy to see that the depicted element is not a ‘pole’ in any conventional
`sense”). Caravan relied only upon Figures 3 and 4 of the ’040 Patent to argue that
`the center pole disclosed in those figures is not an elongated element. Id. at 21. The
`court adopted Caravan’s proposed construction of the term “center pole” without
`explanation. Ex. C (Civil Minutes, E-Z Up Case, Dkt. 96), at 1.
`III. LEVEL OF ORDINARY SKILL IN THE ART
` A person of ordinary skill in the art (“POSITA”) as of the effective filing
`date of the ’040 Patent would have had a degree in the mechanical arts or a related
`discipline and at least two years of experience in the design or analysis of
`mechanical devices, fabricated frames, and/or kinematic linkages, though additional
`work experience could substitute for a formal degree, and vice versa.
`IV. CLAIM CONSTRUCTION LEGAL PRINCIPLES
`Claim construction is a matter of law. Markman v. Westview Instruments,
`Inc., 517 U.S. 370, 388-91 (1996). Claim terms are viewed from the perspective of
`a POSITA. “[T]he person of ordinary skill in the art is deemed to read the claim
`term not only in the context of the particular claim in which the disputed term
`appears, but in the context of the entire patent, including the specification.” Phillips
`v. AHW Corp., 415 F.3d 1303, 1313 (Fed. Cir. 2005). The same term in the same
`patent is presumed to carry the same meaning. Aug. Tech. Corp. v. Camtek, Ltd.,
`655 F.3d 1278, 1284 (Fed. Cir. 2011). The question for the Court is how the person
`of ordinary skill in the art would understand the claim terms in the context of the
`specification and prosecution history. Thorner v. Sony Computer Entm’t Am. LLC,

`There “are only two exceptions to this general rule: 1) when a patentee clearly
`sets out a definition and acts as his own lexicographer, or 2) when the patentee
`disavows the full scope of a claim term either in the specification or during
`prosecution.” Id. To be a lexicographer, the “patentee must clearly set forth a
`definition of the disputed claim term other than its plain and ordinary meaning.” Id.
`(quotation omitted).
`V. CONSTRUCTION OF THE DISPUTED TERMS
`A. The claim term “center pole” should be construed to mean a
`“centrally-disposed, long, slender object”.
`
`Claim Term
`“center pole”
`(claim 1)
`
`Defendants’ Construction
`Plaintiff’s Construction
`centrally-disposed, long,
`Centrally disposed element for
`slender object
`stretching and sustaining a tent’s roof
`i.
`The Court should adopt Defendants’ construction.
`Independent claim 1 of the ’040 Patent recites “a center pole used for
`stretching and sustaining a tent’s roof when pitching a tent.” Dkt. 1-1 (’040 Patent),
`2:14-16. For several reasons a POSITA would understand the “center pole” portion
`of this phrase to mean a “centrally-disposed, long, slender object.” First, the ’040
`Patent uses “center” consistent with its plain and ordinary meaning—in the middle.
`The specification describes center pole ribs 30 connecting the center pole 50 to each
`of the side poles 10, such that the center pole 50 is equidistant from each of the side
`poles. Id., 2:64-3:1. Caravan’s proposal likewise captures the fact that the “center
`pole” is “[c]entrally disposed”. Dkt. 90-1, at 1.
`Second, the intrinsic record confirms that “pole” means “long, slender
`object”. The only disclosure related in the specification is that the center pole 50
`“has a simple construction” and connects to each of the center pole ribs 30 as shown
`in Figures 3 and 4. Dkt. 90-1 (’040 Patent), 2:64-65, 4:2-3, Figs. 3, 4. Claim 1 also
`references both “center pole” and “side poles”. A presumption exists “that the same
`terms appearing in different portions of the claims should be given the same

`meaning unless it is clear from the specification and prosecution history that the
`terms have different meanings at different portions of the claims.” Fin Control Sys.
`Pty., Ltd. v. OAM, Inc., 265 F.3d 1311, 1318 (Fed. Cir. 2001). Neither the
`specification nor prosecution history indicate that “pole” should carry a different
`meaning when used in “center pole” versus “side poles.” Thus, “pole” should be
`given the same meaning wherever it is used in the claims and regardless of what
`descriptive terms come before it.
`For both the center and side “pole,” the patent uses the term to refer to a long,
`slender object. When referring to the “center pole” for prior art frames, the ’040
`Patent depicts Element 6, which is a long, slender object (see the center image,
`below). The same is true when the patent identifies the “center pole 50” in the
`preferred embodiment of the alleged invention; namely, it is a long, slender object
`(see the left-most image below). The applicant did not use a different term to
`describe this feature of the depicted frames, opting instead for the same term in both
`instances. While the “center pole 6” in the prior art frame is longer than the “center
`pole 50” shown in Figures 3 and 4, both are still long, slender objects.
`The same is true with respect to the patent’s treatment of the word “pole” as
`used in “center pole” and “side poles”. As a preliminary matter, the words “center”
`and “side” denote the location of the pole, not additional structure or modification of
`the pole. Further, both the “center pole 50” and “side poles 10” are long and slender
`(compare the left-most and right-most images, below). While the “side poles” are
`longer than the “center pole,” in both instances the poles have an identifiable length.

`
`The prosecution history likewise supports Defendants’ construction. During
`prosecution, the examiner stated that Lynch taught a center pole 50. Ex. A, at 52.
`The applicant, however, never distinguished the structure of the Lynch center pole.
`Thus, the apex portion 50 of Lynch, shown in Lynch’s Figure
`2 (excerpted to the right) as a long, slender piece, is a “center
`pole” that closely resembles the preferred embodiment’s
`center pole (’040 Patent, Element 50).2
`Third, extrinsic evidence support’s Defendants’
`construction. Common dictionaries at the time of the alleged invention define a pole
`as “a long, cylindrical, often slender piece of wood, metal, etc.,” Ex. D (Webster’s
`Encyclopedic Unabridged Dictionary of the English Language (1996)), and “a long,
`slender, usually cylindrical object (as a length of wood),” Ex. E (Merriam-Webster’s
`Collegiate Dictionary, Tenth Edition (2000)). The ’040 Patent depicts such a long
`and slender object, with the distinction that it need not be cylindrical.
`
`2 The prosecution history also supports Defendants’ position because the applicant
`amended claim 1 as follows: “a center pole [used] constructed for stretching and
`sustaining a tent’s roof when [pitching] a tent is pitched with the tent frame.” Ex. A.
`The applicant explained that while not amended in view of the prior art, the
`amendment was designed to “more particularly point out and distinctly claim the
`present invention.” Id. In other words, the center pole of the invention is not just
`used to stretch and sustain the roof, it must be constructed (or built) in a manner that
`carries out that purpose. This fact reinforces the point that a “pole” must be a “pole”
`and not some amorphous element “for” stretching and sustaining a tent’s roof.

`ii.
`Plaintiff’s proposal is wrong.
`Caravan proposes that the Court construe “center pole” as a “[c]entrally
`disposed element for stretching and sustaining a tent’s roof”. Dkt. 90-1, at 2.
`Preliminarily, Caravan’s attempt to eliminate “pole” is an attempt to broaden the
`claim to cover a flat disk—far beyond the scope of the ordinary meaning of “pole”.
`For example, in its infringement contentions against Walmart, Caravan identified a
`flat disk that is wider than it is long as the claimed “center pole”:
`
`
`
`
`
`Dkt. 78-3, at 38. Defendants, of course, do not argue that Caravan’s infringement
`theories should govern during the claim construction process. But while “a trial
`court should certainly not prejudge the ultimate infringement analysis by construing
`claims with an aim to include or exclude an accused product or process, knowledge
`of that product or process provides meaningful context for the first step of the
`infringement analysis claim construction.” Wilson Sporting Goods Co. v. Hillerich
`& Bradsby Co., 442 F.3d 1322, 1326-27 (Fed. Cir. 2006).
`Caravan bases its construction on various intrinsic record cites and the claim
`construction materials from the E-Z Up Case. In the E-Z Up Case, Caravan relied
`on Figures 3 and 4 to argue that the applicant acted as its own lexicographer. Ex. B,
`at 20-21. According to Caravan, the applicant allegedly “used the term ‘center pole’

`
`to refer generally to a central element.” Id. at 21.
`This is incorrect. “To act as its own lexicographer, a patentee must clearly set
`forth a definition of the disputed claim term, and clearly express an intent to define
`the term.” GE Lighting Solutions, LLC v. AgiLight, Inc., 750 F.3d 1304, 1309 (Fed.
`Cir. 2014) (quotation omitted). Yet the ’040 Patent does not contain any “words or
`expressions of manifest exclusion or restriction” broadening “pole” to any
`“element,” and Caravan has thus far pointed to none. Teleflex, Inc. v. Ficosa N. Am.
`Corp., 299 F.3d 1313, 1327 (Fed. Cir. 2002). To the contrary, as shown above, the
`term is used consistently to describe both the prior art and preferred embodiment.
`Caravan argued in the E-Z Up Case that limiting “center pole” to something
`requiring a “pole” excluded the only embodiment of the patent. Ex. B, at 21. That
`too is incorrect. As the prior discussion reveals (see supra, §V.A.i), all examples of
`“center pole” in the ’040 Patent depict a centrally-disposed, long, slender object—in
`other words, a centrally-disposed pole. Construing this term according to
`Defendants’ proposal does not exclude an embodiment from the scope of the claims.
`Caravan’s proposal would also render a portion of claim 1 meaningless.
`Claim 1 recites: “a center pole constructed for stretching and sustaining a tent’s roof
`when a tent is pitched with the tent frame …” Replacing “center pole” with
`Caravan’s construction renders the “for stretching and sustaining language”
`superfluous: “… a [c]entrally disposed element for stretching and sustaining a tent’s
`roof constructed for stretching and sustaining a tent’s roof …”
`Caravan’s proposed construction cannot be correct because constructions
`should not rend
