MEMORANDUM
YOUNG, District Judge.
I. INTRODUCTION
This Markman memorandum explains this Court's construction of design patent D677,423 (the "'423 patent") which claims an "ornamental design for a bathroom vanity light shade." U.S. Patent No. D677,-423 (filed Mar. 8, 2012). Compl., Ex. A, ECF No. 1-2. On June 4, 2014, at a Markman hearing, this Court, acting on behalf of Judge Tauro to whom this case was originally drawn, orally construed the patent at bar. Pursuant to the Court's internal procedures, the case was subsequently transferred to Judge Talwani for all further proceedings. This memorandum details the Court's reasoning.
A. Procedural History
The plaintiff, Maureen Reddy ("Reddy"), brings suit against Lowe's Companies, Inc. and Evolution Lighting, LLC (collectively, the "Defendants"), accusing the Defendants of infringing her design patent.

B. Patent Description
The '423 patent, entitled "Bathroom Vanity Light Shade," claims an "ornamental design for a bathroom vanity light shade, as shown and described" in five attached figures. '423 Patent. The '423 patent contains brief descriptions of each of the five figures, which mainly serve to identify the perspective from which the figures are drawn (e.g., "FIG 1 is a front perspective view from below of a bathroom vanity light shade showing my new design"). Id. Below the descriptions of the individual figures is a general description of the invention, which reads as follows:
The bathroom vanity light shade is an ornamental fixture consisting of a rectangular, metal rod skeleton, wrapped in fabric on three sides (front side, left side, right side), with a stationary acrylic diffuser bottom. The bathroom vanity light shade mounts on the wall .with a top/back exposed mounting rod.

II. ANALYSIS
A. Defining Design Patents
Under United States patent laws, inventors may claim two different types of patents: utility patents, which cover "new and useful" inventions, 35 U.S.C. § 101, and design patents, which apply to "new, original and ornamental design[s] for an article of manufacture," 35 U.S.C. § 171. See also, e.g., International Seaway Trading Corp. v. Walgreens Corp., 589 F.3d 1233, 1238 (Fed.Cir.2009) (contrasting requirements for utility patents versus design patents). Befitting their different names, design patents "contemplate not so much utility as appearance," Gorham Mfg. Co. v. White, 81 U.S. 511, 524, 14 Wall. 511, 20 L.Ed. 731 (1871), and as such, the patent's focus on aesthetic impression is somewhat akin to copyright protection for works of art. See Mazer v. Stein, 347 U.S. 201, 218, 74 S.Ct. 460, 98 L.Ed. 630 (1954).
Accordingly, the scope of a design patent varies from that of a utility patent: it is the form of the object that is claimed, not the object itself. "In a design patent application, the subject matter which is claimed is the design embodied in or applied to an article of manufacture (or portion thereof) and not the article itself." Manual of Patent Examining Procedure ("MPEP") (9th ed. Rev. Mar. 2014) § 1502 (citing Ex parte Cady, 1916 C.D. 62, 232 O.G. 621 (Comm'r Pat.1916)). "The design for an article consists of the visual characteristics or aspect displayed by the article. It is the appearance presented by the article which creates an impression through the eye upon the mind of the observer." Id. § 1502, ¶ 15.42. Only the ornamental aspects of the design are protected: any functional elements are beyond the scope of the patent. Richardson v. Stanley Works, Inc., 597 F.3d 1288, 1293-94 (Fed.Cir.2010).
Design patents differ in scope from utility patents across several key distinctions. First, the design patent's focus is on its figures, not its text, and "[n]o [written] description, other than a reference to the drawing, is ordinarily required." 37 C.F.R. § 1.153(a); see also MPEP § 1503.01, ¶ 15.05(11) ("No description of the design in the specification beyond a brief description of the drawing is generally necessary, since as a rule the illustration in the drawing views is its own best description." (citing In re Freeman, 23 App. D.C. 226 (App.D.C.1904))). Thus, while the metes and bounds of a utility patent are established by the language of its claims, the metes and bounds for a design patent are established by its figures. See Rebecca Tushnet, The Eye Alone is the Judge: Images and Design Patents, 19 J. Intell. Prop. L. 409, 409-10 (2012) ("The law requires a 'written description' of patent claims, but the drawing is the written description for design patents."). Second, unlike utility patents, design patents are limited to only a single claim. 37 C.F.R. § 1.153(a) ("More than one claim is neither required nor permitted."). Finally, the design patent drawings themselves are subject to relatively stringent technical requirements. See 37 C.F.R. § 1.152; MPEP § 1503.02.
B. Design Patent Claim Construction
As with utility patents, design patents are subject to claim construction by the court pursuant to Markman v. Westview Instruments, Inc., 517 U.S. 370, 116 S.Ct. 1384, 134 L.Ed.2d 577 (1996). In Egyptian Goddess, Inc. v. Swisa, Inc., 543 F.3d 665 (Fed.Cir.2008) (en banc), the Federal Circuit established the principles a district court must employ when it so constructs. This -decision controls the instant case and as such, the Court will consider in depth both it and its progeny.
1. The Egyptian Goddess Framework
The Federal Circuit starts with the premise that the district court has considerable discretion in constructing design patents, and as such, the Federal Circuit does not "prescribef ] any particular form that the claim construction must take," but rather "recognize[s] that design patents typically are claimed as shown in drawings, and that that claim construction is adapted accordingly." Id. at 679 (internal citations and quotation marks omitted). Accordingly, the district court is not required to "attempt to provide a detailed verbal description of the claimed design." Id. Instead, "[gjiven the recognized difficulties entailed in trying to describe a design in words, the preferable course ordinarily will be for a district court not to attempt to 'construe' a design patent claim by providing a detailed verbal description of the claimed design." Id.
The Federal Circuit clarified its "preferable course" language, concluding that a verbal description could be attempted, but warning in relatively strong terms that such an endeavor is inadvisable:
[I]t is important to emphasize that a district court's decision regarding the level of.detail to be used in describing the claimed design is á matter within the court's discretion, and absent a showing of prejudice, the court's decision to issue. a relatively detailed claim construction' will riot be reversible error. At the same time, it should be clear that the court is not obligated to issue a detailed verbal description of the design if it does not regard verbal elaboration as necessary or helpful. In addition, in deciding whether to attempt a verbal description of the claimed design, the court should recognize the risks entailed in such a description, such as the risk of placing undue emphasis on particular features of the design and the risk that a finder of fact will focus on each individual described feature in the verbal description rather than on the design as a whole. In this case, for example, the district court came up with a detailed verbal description of the claimed design. We see no inaccuracy in the court's description, and neither party has pointed to any prejudice resulting from the court's interpretation. Yet it is not clear that the considerable effort needed to fashion the verbal description contributed enough to the process of analyzing the case to justify the effort.
Id. at 679-80.
Notwithstanding this warning, the trial court does not abdicate all interpretative responsibilities when faced with a design patent. Rather:
[A] trial court can usefully guide the finder of fact by addressing a number of .other issues that bear on the scope of the claim. Those include such matters as describing the role of particular conventions in design patent drafting, such as the role of broken lines; assessing and describing the effect of any representations that may have been made in the course of the prosecution history; and distinguishing between those features of the claimed design that are ornamental and those that are purely functional.
Id. at 680 (internal citations omitted). The district court also could play a role in highlighting for the fact finder "various features of the claimed design as they relate to the accused design and the prior art." Id. Finally, the Egyptian Goddess court closed by emphasizing that the choice in how to construe design patents was ultimately committed in large part to the discretion of the district court:
Providing an appropriate measure of guidance to a jury without crossing the line and unduly invading the jury's fact-finding process is a task that trial courts are very much accustomed to, and any attempt by an appellate court to guide that process in detail is likely to do more harm than good. We therefore leave the question of verbal characterization of the claimed designs to the discretion of trial judges, with the proviso that as a general matter, those courts should not treat the process- of claim construction as requiring a detailed verbal description of the claimed design, as would typically be true in the case of utility patents.
Id.
2. Interpreting Egyptian Goddess
In the six years since Egyptian Goddess, the Federal Circuit and the district courts have generally used the court's grant of discretionary authority to eschew textual interpretations of design patents, except under limited circumstances.
In some cases, courts will issue written constructions if a design patent incorporates both unprotected functional elements and protected ornamental elements, in order to focus the fact finder's attention on the latter. See, e.g., Richardson, 597 F.3d at 1293; Nordock Inc. v. Sys. Inc., 927 F.Supp.2d 577, 587-90 (E.D.Wis.2013); Unique Indus., Inc. v. 965207 Alberta Ltd., 722 F.Supp.2d 1, 8-9 (D.D.C.2009).
But many courts have held that inquiries into functionality or prosecution history are more appropriate at a later stage in the litigation, such as summary judgment or jury instructions. In Depaoli v. Daisy Manufacturing Co., Inc., No. 070-cv-11778-DPW, 2009 WL 2145721 (D.Mass. July 14, 2009) (Woodlock, J.), Judge Wood-lock concluded that even if prosecution history and functionality are relevant, in order to prevent placing "undue emphasis" on certain elements of the design, they ought be addressed at the summary judgment or jury instruction stage, rather than' the claim construction stage. Id. at *5; see also Dexas Int'l, Ltd. v. Office Max Inc., No. 6:07-cv-396, 2009 WL 252164, at *5-6 (E.D.Tex. Jan. 30, 2009) ("Dexas II") (same).
Similarly, while courts have recognized that Egyptian Goddess allows for a judge's examination of prior art, they have generally left such considerations for post-claim construction interpretations, mainly to avoid putting "undue emphasis on particular features of the design." OraLabs, Inc. v. Kind Group LLC, No. 13-CV-00170-PAB-KLM, 2014 WL 1630690, at *4 (D.Colo. Apr. 24, 2014) (internal citations and quotation marks omitted). These courts have viewed prior art as part of the infringement analysis, not the construction analysis. Apple, Inc. v. Samsung Elees. Co., Ltd., No. 11-CV-01846-LHK, 2012 WL 3071477, at *3 (N.D.Cal. July 27, 2012) (holding that "the limitation in scope of a design patent in light of prior art is necessarily folded into the infringement analysis").
By and large, in the wake of Egyptian Goddess, district courts have heeded the Federal Circuit's warning of the dangers of "undue emphasis on particular features" of the patented design and "away from consideration of the design as a whole." Crocs, Inc. v. Int'l Trade Comm'n, 598 F.3d 1294, 1302-03 (Fed.Cir.2010). Accordingly, they have declined to provide detailed claim constructions of design patents. See, e.g., OraLabs, 2014 WL 1630690, at *5; Apple, 2012 WL 3071477, at *2.
C. Proposed Constructions
As is common in patent infringement cases, the parties propose dramatically different claim constructions:
Reddy "The ornamental design for a bathroom vanity light shade, as shown and _described in Figures 1-5."_
Defendants "A light shade adapted to fit over an existing wall light fixture having (i) a front rectangular surface in the form of a flat plane comprising a fabric surface, (ii) substantially square side surfaces in the form of flat planes comprising fabric surfaces, (iii) a flat rectangular bottom surface comprising an acrylic diffuser, and (iv) having open top and back surfaces with a metal rod extending between the upper rear corners of the side surfaces, wherein all corners are right angles and all edges are straight and are either vertical or horizontal."
Pl.'s Opening Br. 6; Defs.' Opening Br. 10.
As an initial matter, the Defendants' proposed construction, which focuses attention on a list of specific elements rather than the overall design presented in the figures, creates a "risk of placing undue emphasis on particular features of the design and the risk that a finder of fact will focus on each individual described feature in the verbal description rather than on the design as a whole." Egyptian Goddess, 543 F.Sd at 680; see also Amini Innovation Corp. v. Anthony Cal., Inc., 439 F.3d 1365, 1371 (Fed.Cir.2006) ("It is the drawings in the patent, not just one feature of the claimed design, that define the patented design."). Accordingly, this Court rejects the Defendants' construction in favor of Reddy's proposal, which is a simpler interpretation of the patent that accords more closely with the types of constructions adopted by post -Egyptian Goddess courts. Nonetheless, the Defendants raise several arguments which the Court will address.
1. Claim Description Language
First, the Defendants highlight two sentences in the patent's description, which they argue limit the '423 patent's scope to embody only certain materials, and, accordingly, must be considered during the claim construction. See Defs.' Opening Br. 3-4; Defs.' Reply 7-9.
As discussed above, and reproduced below, the patent in question contains a two-sentence general description (the "written description paragraph") that follows the individual figure descriptions:
The bathroom vanity light shade is an ornamental fixture consisting of a rectangular, metal rod skeleton, wrapped in fabric on three sides (front side, left side, right side), with a stationary acrylic diffuser bottom. The bathroom vanity light shade mounts on the wall with a top/back exposed mounting rod.
'423 patent. The Defendants argue that this paragraph means that "the design of the bathroom vanity light shade in the '423 patent requires at least a fabric covering on three sides (front, left, and right), and a stationary acrylic diffuser bottom," even though such features are not shown in the illustration. Defs.' Reply 7. In so doing, they make two arguments: first, a general argument that all words in a patent must be given effect, and that in order to do. that here, the Court must adopt their proposed construction, and second, a specific argument that the materials mentioned in the paragraph are protected "surface treatment" elements of the design. See id. at 3-5, 7-8. The question for this Court, then, is what weight, if any, this paragraph ought be given in light of those arguments.
a. General Argument About Incorporation
Defendants posit that the written description paragraph ought be incorporated into the patent. Their argument, while not a model of clarity, appears to be twofold: (1) the patent claims an "ornamental design for a bathroom vanity light shade, as shown and described," '423 patent (emphasis added), and (2) in order to avoid rendering "the claim language referencing the description . [as] superfluous and meaningless," that language must be incorporated into the patent. Defs.' Opening Br. 3.
The Defendants are correct that there is a general claim construction axiom which holds that, if possible, "[a] claim construction that gives meaning to all terms of the claim is preferred over one that does not do so." Id. at 4 (quoting Merck & Co., Inc. v. Teva Pharm. USA, Inc., 395 F.3d 1364, 1372 (Fed.Cir.2005)). This general rule of construction, however, conflicts with one specific to design patents: that "[i]t is the drawings of the design patent that provide the description of the invention." In re Daniels, 144 F.3d 1452, 1456 (Fed.Cir.1998). Indeed, "[u]n-like utility patents, design patents do not describe claimed designs in words.... Accordingly, design patents have almost no scope; they are limited to what is shown in the application drawings." Concept Innovation v. CFM Corp., No. 04-C-3345, 2004 WL 2812109, at *1 (N.D.Ill. Dec. 7, 2004) (citing Elmer v. ICC Fabricating, Inc., 67 F.3d 1571, 1577 (Fed.Cir.1995)). Under this "figure-only" framework, any written description that goes beyond the scope of the figures would be unprotected by the patent, and thus ought not be part of the construed claim. Thus, the references to "wrapped in fabric" and an "acrylic diffuser bottom," since they are not shown in the figures, would stretch beyond the patent.
In response, the Defendants point to 37 C.F.R. § 1.153, which governs the descriptions required of a design patent, and which states that "[n]o description, other than a reference to the drawing,-is-ordinarily required." 37 C.F.R. § 1.153(a). The use of "ordinarily," they argue, "signifies that cases may exist in which it is anticipated that a written description may be required in order to properly delineate the claimed design and distinguish it over prior art." Defs.' Reply 5. The Defendants are correct that the word "ordinarily" invites the possibility of an exception, as does the Patent Examiner's Manual, which states that "while not required, such a [written] description is not prohibited and may be incorporated, at applicant's option, into the specification or may be provided in a separate paper." MPEP § 1503, ¶ 15.59(11). .
These provisions, however, provide little comfort to the Defendants. The Defendants do not point to any case law indicating that a district court can incorporate features described in writing, but not shown in the figures, into its construction. Moreover, the case they do rely on, Arminak & Associates, Inc. v. Saint-Gobain Calmar, Inc., 501 F.3d 1314 (Fed.Cir.2007), abrogated by Egyptian Goddess, 543 F.3d 665, stands for the proposition that Federal Circuit case law "does not prohibit detailed claim construction of design patent drawings. It merely disapproves claim construction that goes beyond the novel, nonfunctional ornamentation features visually represented by the claimed drawings." Defs.' Reply 4 (emphasis omitted) (quoting Arminak, 501 F.3d at 1321). Such a holding still requires the constructed element to be apparent in the features that are "visually represented" in the drawings; it says nothing about features that are represented only in writing. Indeed, by stating' that it "disapproves claim construction that goes beyond . features visually represented" in the drawings, the Federal Circuit suggested that writing-only features are to be disregarded. Id. Similarly, the regulations setting out the process by which design patents are submitted requires that "[t]he design must be represented by a drawing." 37 C.F.R. § 1.152. The regulation does not say that the design can be represented by a written description alone and, again, suggests the opposite.
In light of this context, this Court holds that the United States Patent and Trademark Office regulations that allow a written description are limited only to written descriptions that clarify features on an existing drawn figure: they do not authorize written descriptions that add features not present on the figure. Accordingly, this Court does not construe "fabric side" and "acrylic diffuser bottom" as part of the patent claim, since these specific features are not shown in the figure.
b. Surface Treatment Features
The Defendants concede that the fabric covering and acrylic diffuser bottom are "not shown in the illustrations." Defs.' Reply 7. Nonetheless, they argue that such features must be included in the claim because they are "surface treatments." The MPEP defines surface treatments as follows:
The ornamental appearance of a design for an article includes its shape and configuration as well as any indicia, contrasting color or materials, graphic representations, or other ornamentation applied to the article' ("surface treatment"). Surface treatment must be applied to or embodied in an article of manufacture. Surface treatment, per se (i.e., not applied to or embodied in a specific article of manufacture), is not proper subject matter for a design patent under 35 U.S.C. 71. Surface treatment may either be disclosed with the article to which it is applied or in which it is embodied and must be shown in full lines or in broken lines (if unclaimed) to meet the statutory requirement.
MPEP § 1503.02, ¶ 15.50.06(IV).
The Defendants argue that the fabric and acrylic in the design patent are surface treatments, and thus ought be part of the construction. Defs.' Reply 7-8. This argument fails. Although the MPEP states that "materials" can be part of a surface treatment (and thus protected), the word "materials" must be read in the context of the sentence in which it appears. Graham Cnty. Soil & Water Conservation Dist. v. U.S. ex rel. Wilson, 559 U.S. 280, 287, 130 S.Ct. 1396, 176 L.Ed.2d 225 (2010) (translating the statutory interpretation canon noscitur a sociis to "a word may be known by the company it keeps"). In the MPEP, "materials" is part of the list item "contrasting colors or materials," which itself is one of several items connoting visual design (e.g. "graphic representations" or "ornamentation"). In this context, then, the word "materials" means the use of material to create a visual design (e.g., a cross-hatch pattern), rather than the un derlying "foundational material" (e.g., the material of which the product is made).
Even if the fabric and acrylic materials were considered surface treatments, they still ought not be incorporated into the construction. The MPEP requires that the surface treatment "must be shown in full lines or in broken lines (if unclaimed) to meet the statutory requirement." MPEP § 1503.02, ¶ 15.50.05(IV). Here, there is no specific indication of fabric or acrylic material in the figures. At best, there is an indication of translucent or transparent materials (as defined by the use of oblique lines, see MPEP § 1503.02, ¶ 15.48(11)), but there is no suggestion in the figures as to what materials must be used to create that transparent effect,
c. Necessary Complications
To be sure, the references to fabric sides and a stationary acrylic diffuser bottom in the patent description are troubling, and they probably ought not have been included when the patent was issued. But considering that design patents only cover what appears in the figures, the lack of case law supporting a construction of a design patent element mentioned only in a written description, and the fact that the materials do not appear to meet the "surface treatment" classification in the MPEP, this Court declines to incorporate these sentences into its construction. Rather, the Court will hold off determining their precise import, if any, until later in the litigation, when the parties can address the issue of whether these elements are functional, or whether they are akin to a "preferred embodiment" in a utility patent.
Such á ruling will effectively read these two sentences out of the patent, which this Court recognizes as a disfavored outcome. Cf. Curtiss-Wright Flow Control Corp. v. Velan, Inc., 438 F.3d 1374, 1382 (Fed.Cir.2006). Nonetheless,, in light of the case law which strongly teaches that figures, not text, control the bounds of design patents, the emphasis on ornamentation in design patent law, and the lack of controlling case law on superfluous written description language in a design patent, the Court's ruling will do less violence to the patent than would incorporating unprotected elements into the claim.
2. Prosecution History and Prior Art
The Defendants next argue that the Court ought consider prior art and the '423 patent's prosecution history when construing the claim. Defs.' Opening Br. 4-9. Reddy argues that such interpretative steps are inappropriate at the claim construction stage and ought be left until the jury instruction phase of litigation. See Pl.'s Reply 5-7.
As discussed above, Egyptian Goddess specifically provides that prosecution history and prior art are "helpful" and can be "useful[ ]" to a finder of fact. 543 F.3d at 680. District courts interpreting Egyptian Goddess have, however, generally chosen to issue such guidance in the form of jury instructions, rather than as part of the claim construction. See, e.g., OraLabs, 2014 WL 1630690, at *5; Blackberry Ltd. v. Typo Prods., LLC, No. 14-CV-00023-WHO, 2014 WL 1318689, at *3 (N.D.Cal., Mar. 28, 2014); Depaoli, 2009 WL 2145721, at *10. But see Apple, 2012 WL 3071477 at *9-10 (considering prosecution history as part of its claim construction opinion). Postponing such adjudication, as Judge Woodlock reasoned, avoids the risk of placing "undue emphasis" on certain elements of a design, which is "precisely the danger against which the Egyptian Goddess court cautioned." Depaoli, 2009 WL 2145721, at *5. Such reasoning applies here, for the reasons Judge Woodlock articulated.
There are also two additional considerations that apply in this case. First, the discussion of prior art is quite undeveloped. The Defendants mention three other U.S. patents: Patent 7,156,537, 4,045,665, and 7,213,950. Defs.' Opening Br. 4-6. While the Defendants do discuss some of the similarities between the prior art and the '423 patent, such discussion focuses on the presence or absence of specific features, rather than similarities in the overall impressions of the two patents, which is the more appropriate focus when interpreting design patents. See Defs.' Opening Br. 4-6, 8-9; MRC Innovations, Inc. v. Hunter Mfg., LLP, 747 F.3d 1326, 1335 (Fed.Cir.2014). Moreover, the Defendants mention only three patents, all utility, even though the'423 patent mentions twenty-four prior art references cited by the patent examiner (twenty of them design patents). To be sure, utility patents can constitute relevant prior art when considering design patents, see Application of Aslanian, 590 F.2d 911, 913-14 (C.C.P.A.1979), although how utility patents are to be used for that objective is not well established in the case law, see, e.g., Simmons, Inc. v. Koronis Parts, Inc., No. Civ. 00-1984ADM/RLE, 2001 WL 1095008, at *3 (D.Minn. Sept. 17, 2011). In this case, however, the Defendants' complete omission of any design patents (especially when design patents constitute the bulk of the references cited by the examiner), suggests that the prior art analysis is not yet fully briefed, and that any ruling on such a basis is premature.
Second, while the prosecution history discussion is more developed in the briefing than the prior art analysis, it is, at best, ambiguous, and risks placing "undue emphasis" on certain elements of the design, in direct contravention of the teachings of Egyptian Goddess. Depaoli, 2009 WL 2145721, at *5. The relevant prosecution history is as follows.
On November 7, 2012, the patent examiner determined that while the patent generally was proper, "[t]he specification is objected to because the descriptions do not accurately describe the views shown in the drawing disclosure." Prosecution History of the '423 Patent, Office Action Summary 7, ECF No. 32-2. The examiner noted that the perspective labels on the figures were incorrect, stating: "the drawings include all perspective views of the claimed design; however, the views are described at elevation views." Id. The office then required Reddy to amend the figure descriptions to reflect their proper orientation. The examiner also required Reddy to describe how broken lines were used in the figures, as well as to correct the drawings to remedy the images' "poor line quality." Id. at 7-8. Next, the examiner noted "several inconsistencies among the views," such as the fact that one figure indicated that a side of the design was open, while "the remaining views indicate the design has four closed fabric sides, a bottom acrylic closed surface and a single open side on the rear of the design." Id. at 8-9. Finally, for these purposes, the examiner also criticized the shading of the figure, noting that the applicant "indicates the bottom rectangular surface is an acrylic diffusing surface; however, the proper oblique line shading is not included on the bottom surface to indicate transparent/translucent/reflective." Id. at 9. In response to these concerns, Reddy amended her figure descriptions accurately to reflect the orientation of their associated figures, and redrew the figures "to show clean uniform, and well defined lines" as well as the appropriate shading. Prosecution History of the '423 Patent, Reddy Resp./Am. Mar. 8, 2012, at 3, ECF No. 32-2.
The Defendants argue that Reddy's responses during prosecution estop her here, stating that:
The applicant's response to the Office Action indicates an acceptance of the examiner's objection, and creates an es-toppel that limits the claim to a diffuser as stated in the description, ie., a stationary acrylic diffuser bottom surface. Furthermore, the examiner's reference to the description as indicating that the design incorporated an acrylic diffusing surface would also require that the design consists of a metal rod skeleton wrapped in fabric on three sides, as recited .in the '423 patent. In light of the drawings that show nothing more than a right rectangular prism with some surfaces showing one of two shadings and others being open, the written description referenced in the claim is necessary to provide essential ornamental features to the otherwise unorna-mented shape depicted in the drawings.
Defs.' Opening Br. 7.
The Defendants' argument is unavailing. The focus of the examiner's comments was on ensuring that the figures themselves were clear, internally consistent, and in accordance with USPTO shading and line-definition requirement documents. This would suggest that the shading and draftsmanship of the figure was important to the USPTO, but not necessarily that the material used was important. Accordingly, given that these prosecution remarks could be subject to' multiple interpretations, and given that prosecution history is often ambiguous and "thus is less useful for claim construction purposes," Phillips v. AWH Corp., 415 F.3d 1303, 1317 (Fed.Cir.2005), this Court declines to incorporate the prosecution history into the construction. The Court's ruling is, of course, without prejudice to a future assessment of prosecution history at the jury instruction stage.
III. CONCLUSION
For the reasons stated above, on June 4, 2014, this Court ADOPTED Reddy's proposed claim construction: "The ornamental design for a bathroom vanity light shade, as shown and described in Figures 1-5." Elec. Clerk's Notes, June 4, 2014, ECF No. 42.
This construction is without prejudice to any future jury instructions on functional versus ornamental elements, prosecution history, prior art, or any other similar factors.
SO.ORDERED.
. Despite these differences, design patents are nonetheless subject to essentially the same general requirements as are utility patents, e.g., novelty. 35 U.S.C. § 171; Peter Lee & Madhavi Sunder, Design Patents: Law Without Design, 17 Stan. Tech. L.Rev. 277, 281-82 (2013).
. Even when functional elements are implicated, however, courts will generally defer to the figures unless the features are indisputably and wholly functional. See Good Sportsman Mktg. LLC v. Li & Fung Ltd., No. 6:07-cv-395, 2010 WL 2640385, at *3-4 (E.D.Tex. June 29, 2010).
. Some courts have elected to provide detailed verbal descriptions, of course, and the Defendants point to three: Dexas v. Tung Yung International (USA) Inc. and Tung Yung International, Ltd., No. 6:07-cv-334, 2009 WL 838174, at *2 (E.D.Tex. Feb. 25, 2009) ("Dex-as III")(affirming a claim construction provided in an earlier order, 2008 WL 4831348 (E.D.Tex. June 24, 2008) ("Dexas I")); Shop*TV, Inc. v. Bed Bath & Beyond, Inc., No. 09-CV-00057-REB-CBS, 2009 WL 1965494, at *3 (D.Colo. July 8, 2009); and Unique Industries Inc., 722 F.Supp.2d 1. Defs.' Reply 6. None of these cases persuades the Court that a detailed claim construction in this case would be necessary or helpful. The Dexas III court merely declined to vacate the detailed claim construction it had authored prior to Egyptian Goddess. Indeed, in an opinion authored by the same judge in a related case that post-dated Egyptian Goddess, the court declined to offer a detailed claim construction for the very same patents, noting that "claim constructions like those adopted in [Dexas I] are neither necessary nor helpful in this case." Dexas II, 2009 WL 252164 at *3. The written constructions offered by the courts in Shop*TV and Unique Industries are equally unavailing because they are far more general than the Defendants propose here.
. There is also a one-sentence disclaimer that indicates that broken lines are not part of the claimed design. '423 Patent.
. A preferred embodiment in a utility patent describes an embodiment of the invention, but does not limit the claim to only that embodiment. See, e.g., Liebel-Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 905-06 (Fed.Cir.2004); Teleflex, Inc. v. Ficosa North Am. Corp., 299 F.3d 1313, 1328 (Fed.Cir.2002) ("We have 'cautioned against limiting the claimed invention to preferred embodiments or specific examples in the specification.' " (quoting Comark Commc'ns, Inc. v. Harris Corp., 156 F.3d 1182, 1186 (Fed.Cir.1998))).
