lection of display objects, called "tools," that have visually distinguishable features (e.g., icons or windows). The
display objects can be shared between workspaces. When a user switches between workspaces to perform different tasks, the display objects or tools that are coÍrmon among the workspaces are displayed in the new workspace. The patents are based on the same disclosure and share a specification. On September 9,2007 IP Innovation, LLC and Technology Licensing Corporation (collectively "IPI") filed this action against Defendants alleging infringement of the three patents.

First, a term's context in the asserted claim can be very instructive. Id. Other asserted or unasserted claims can also aid in determining the claim's meaning because claim terms are typically used consistently throughout the patent. 1d Differences among the claim terms can also assist in understanding a term's meaning.

derlying technology and determining the particular meaning of a term in the pertinent field, but an expert's conclusory, unsupported assertions as to a term's definition is entirely unhelpful to a court. ,Id. Generally, extrinsic evidence is "less reliable than the patent and its prosecution history in determining how to read claim terms." Id.
The patents in suit also contain means-plus-function limitations that require construction. Where a claim limitation is expressed in "means plus function" language and does not recite definite structure in support of its frrnction, the limitation is subject to 35 U.S.C. ô 112,I6. Braun Med., Inc. v. Abbott Labs.. 124 F.3d 1419. 1424 (.Fed.Cir.l997). In relevant part, 35 U.S.C. ô 112, !f 6 mandates that "such a claim limitation 'be construed to cover the corresponding structure ... described in the specification and equivalents thereof.' " Id. (citing 35 U.S.C. $ 112, tf 6). Accordingly, when faced with means-plus-function limitations, courts "must turn to the written description of the patent to furd the structure that corresponds to the means recited in the flimitations]." 1d.

(Fed.Cir.2002). This is true because a patentee may define his own terms, give a claim term a different meaning than the term would otherwise possess, or disclaim or disavow the claim scope. Phillips. 415 F.3d at 1316. In these situations, the inventor's lexicography governs. 1d Also, the specification may resolve ambiguous claim terms "where the ordinary and accustomed meaning of the words used in the claims lack sufficient clarþ to permit the scope of the claim to be ascertained from the words alone." Teleflex. Inc., 299 F.3d at 1325.

multiple inquiries. "The first step in construing [a meansplus-functionl limitation is a determination of the function of the means-plus-function limitation." Medtronic. Inc. v. Advanced Cardiovascular Sys.. Inc., 248 F.3d 1303. 13ll Ged.Cir.200l). Once a court has determined the limitation's function, "the next step is to determine the corresponding structure disclosed in the specification and equivalents thereof." 1d. A "structure disclosed in the specification is 'corresponding' structure only if the specification or prosecution history clearly links or associates that structure to the function recited in the claim." 1d. Moreover, the focus of the "corresponding structure" inquiry is not merely whether a structure is capable of performing the recited function, but rather whether the corresponding structure is "clearly linked or associated with the [recited] function." 1d.

(quoting Constant v. Advanced Micro-Devices, Inc.. 848 F.2d 1560. 1571 (Fed.Cir.1988)); see also Phillios, 4I5 F.3d at 1323. The prosecution history is another tool to supply the proper context for claim construction because a patent applicant may also define a term in prosecuting the patent. Home Diagnostics. Inc.. v. Lifescan. Inc.. 387 F.3d 1352. 1356 (Fed.Cir.2004) ("As in the case of the specification, a patent applicant may define a term in prosecuting a patent.").

Technical dictionaries and treatises may help a court understand the underlying technology and the manner in which one skilled in the art might use claim terms, but tech¡rical dictionaries and treatises may provide definitions that are too broad or may not be indicative of how the term is used in the patent.Id. at 1318.

The parties agree that the term needs no further construction beyond defining "perceptible as the same tool." The parties have agreed on the defuritions for "tool" and "display object." Therefore, the true terms in contention are "perceptible as" and "appears to the user to be the same." IPI argues that these terms as a whole should be defined as
must be rejected. Defendants attempt to define how a computer might achieve object constancy rather than in terms of what perceptible features result in object constancy. Their inclusion of the word "generated" is unsupported by the specification. Though Defendants opine that a "display system object" may "generate" the same tool in multiple workspaces, this portion of the specification has nothing to do with what is perceived by a user. See id. at 8:22-45. Thus, these claim terms do not require, as Defendants argue, that a tooVdisplay object be generated or stored in a certain way. Adding such a limitation to the

Object constancy can result from many cues including similarities of position, size, context, contents, Iabels, text, and/or history." Defendants respond that the terms mean "generated to achieve object constancy such that changes made to shared features of a tool appearing in one workspace, e.g. content, data, etc. are reflected in features oftools in other
workspaces."
FN
definition of the "appearing" terms would improperly limit the claims. Further, while the specification describes that object constancy is achieved through "shared features," Defendants' construction seems to suggest that features must share a data structure to meet the limitation. Nothing in the specification's description of object constancy requires tools/objects to share a data structure. The claim terms only speak to the "appearance" of objects in two workspaces and not how the data structures comprising tools/display objects are organized. One skilled in the art would understand that the "appearing" terms refer to object constancy as described by IPL However, as "object constancy" itself is a specialized term, to include it in the definition of the disputed terms would not assist the jury. But, as described above, the essential characteristic of object constancy is recognition, by the user, of a tooVdisplay object despite some different characteristics. Accordingly, the "appearing" terms mean "recognized as the same tool [display object], even if the
L For ease of reference these terms will collectively be referred to as the "appearing" terms.
IPI's construction is taken directly from the specification describing Figures la and lb. Those Figures show two different windows containing different objects, and the specification explains that the Figures "illustrate the phenomenon of object constancy." '412 Patent at l0:31-3 l.
Some of the objects in the two f,rgures "appear to be the same object despite having different characteristics." 1d. at 10;35-36. As IPI's proffered definition suggests, the specification gives examples of various characteristics that may be different while maintaining object constancy. Id. af 10:36-37 ("postitions, sizes, and contexts"). As an additional example, the specification explains that "[o]ther shared features which can result in object constancy include sharing ofan application, such as an editor; sharing of data; sharing of the state of the application as applied to the data; sharing of a history of continuous operation without intemrption." Id. at 10:43-47.
objects have some different display characteristics, including different positions, sizes, and contexts."
Thus, the term "not including a display object that is perceptible as the same tool" means "not including a display object that is recognized as the same display object, even ifthe objects have some different display characteristics, including different positions, sizes, and contexts."
"display"
The term "display" is used in claims 1,21,24,38,44,49, 56, and 59 of the '472 patent, claims 1 and 8 of the '5 12 patent, andclaims 1,3, and 12 of the'183 patent. IPI defines the term as "an image that includes a collection of display objects together with spatial display relations be-

sent images." The parties agree that the term should have the same definition in all three patents. The principal dispute is whether "display" refers to an "image" or a "de-
vice." The patents' claims contain conclusive evidence that the term "display" refers to a physical device. Most notably,
claim I ofthe'183 patent calls for "a data processor that receives input signals from the user input device and provides output signals to the display; the output signals
causing the display to present images that include display objects." '183 Patent ai 43:62-65. An "image" cannot "present images" nor can it receive "ouþut signals."
term "input means for receiving signals from a user." IPI suggests that the term "input device" means "a keyboard, mouse, or other pointer control device," and Defendants argue the term is restricted to a "mouse or keyboard." IPI further contends that "input means" should be construed the same as "input device," while Defendants urge that the term is a means-plus-function limitation with a function of "receiving signals from a user" and a structure consisting of a "mouse or keyboard, and thei¡ equivalents."
*5 Nevertheless, IPI argues that a "display" is akin to a visual representation of a workspace that, in turn, can
contain other "displays." IPI justifies this theory by pointing to Figure 5, element 100, which shows essentially a desktop filled with different workspaces. See'412 Patenl at Figure 5; 6:39-40. Further, there are instances within the specification that use the word "display" to mean an image. See'412 Patent at 30:36-52 ("the implementation ofexit workspace procedure 204 described above updates the workspace data structure to include data necessary for regenerating substantially the same display at a later time"). IPI suggests that this usage evidences the patentee's overall intention to use "display" consistently throughout the claims as meaning an "image."
IPI first contends that "input" connotes sufficient structure to remove the term "input means" from 35 U.S.C. Q 112 n 6. Essentially, IPI argues that since the phrase "input signals for receiving signals from a user" is understood by one skilled in the art, that the related phrase "input means for receiving signals from a uset'' should be
construed similarly.
There is a presumption that terms containing the word "means" are governed by I I 12 \ 6. TriMed. Inc. v. Stryker Corp.. 514 F.3d 1256. 1259 (Fed.Ctr.2008\. Wl provides no intrinsic evidence overcoming this presumption. The simple factthat the patentee included a similar phrase in a different patent does not constitute evidence of inherent structure. Additionally, as Defendants note, IPI's reliance on Verizon California Inc. v. Ronald A. Katz Technology Licensing. L.P. is misplaced. See 326
F.Supp.2d 1060. 1086-87 (C.D.Ca1.2003). There, the par-
The patents' various usages of the word "display" does not support this conclusion. First, the specification confusingly uses the word "display" as a noun, an adjective, and a verb. In addition, the word "display" is combined with other words to create a variety of different specialized terms such as "display system object," "display object," and "workspace display." Given the wide and varying uses of the term, the patentee clearly had no intention of using the term "display" consistently throughout the
specification. As noted, the claims themselves do not support IPI's defurition. Accordingly, consistent with the usage of "display" in the claims, the Court defures the term as a "device that can be affached to a computer in order to present images."
ties agreed that the term "digital input means" was not
governed by ô 1 12 fl 6 and the court was not clearly presented with the issue disputed here. There is nothing in
the claims or the specification to suggest that "input means for receiving signals from a user" inherently discloses sufficient structure to remove it from e 112 tl 6.
Thus, the Court construes the term under ô I 12 !f 6.
*6 The parties further disagree over whether the definition
of an "input means" and "input device," should include
"other pointer control devices." In addition to a keyboard and a mouse, the specification clearly discloses "other pointer control devices" as a way that a user interacts with the computer. See'412 Patent at l:23-28;34:38-41. Defendants' only argument for excising this phrase from the definition of the disputed terms is that the scope of the I 12 fl 6 equivalence.N phrase is already captured by However, the applicability of lt2 6 requires that a means-plus-function term be given the full scope of the structure described in the specification. 35 U.S.C. $ 112

relationship between a workspace and a workspace data structure, the term "workspace data structure" does not inherently embody such a relationship.

(Fed.Cir.2004). Accordingly, "input means" is governed by Q 112 tf 6 with a function of "receiving signals from a user" and a structure of "a keyboard, mouse, or other pointer control device, and their equivalents." The term "input device" is defmed as "a keyboard, a mouse, or other pointer control device ."
FN2. Defendants' briefing discusses that the scope of "other pointer control devices" is captured by the doctrine of equivalents. However, as the doctrine of equivalents pertains to the issue of direct infringement, the Court assumes that Defendants are referring to $ I 12 tf 6 equivalence.
*7 Defendants also argue that a co-inventor, Stuart Card, has testified to an inherent one-to-one relationship. tn fact, the portion of Mr. Card's deposition that Defendants provided does not squarely address the issue of a one on one relationship. Mr. Card simply agrees that "there are data structures associated with each particular workspace" and not that each workspace only had one data structure associated with it. See Card Depo. Tr., Docket No. 79,8x. D at 120:16-19. There is no evidence that the specification or the claims necessarily tethers a "workspace data structure" to one and only one workspace. As a result, IPI is correct, and the terms "workspace data structure" and "workspace data" do not require definition beyond what
has already been agreed to by the parties.
"workspace datu"
& "workspace
døta structure"
"control megns" Claims l, 24, 38, and 44 of the'412 patent and claim I of the '521 patent contain the term "workspace data structure," and claim 8 of the '521 patent contains the term "workspace data." The parties agree on the definition of "workspace" and "data structure." Rather, the dispute surrounds whether "workspace data" and'owork space data structure" requfue a "one-to-one relationship" between a data structure and a particular workspace. Defendants urge that the terms require a single corresponding data structure for every workspace. IPI contends that the claims do not require such a "one-to-one relationship." There is no question that the specification refers to specific embodiments of the invention with a one-to-one relationship between a data structure and a workspace. ,See '412 Patent at Fig. I (disclosing a particular data structure for each workspace, e.g., workspace A, workspace B, workspace C). However, nothing in the patent's specification disclaims the possibilþ that a single data structure can contain multiple workspaces. See Conoco. Inc. v. En-
Claims l, 38, 49, and 56 of the '412 patent each contain slightly different "control means" limitations. The parties agree that the various limitations are subject to $ 112'tl6 and that the function of each of the terms is set forth in the claim language. Generally, the various functions performed by the control means limitations are: 1) accessing workspace data structures to cause the display to present the workspace; 2) accessing linking data structures to cause the display to present the workspace; 3) accessing display characteristic data while accessing linking data strictures to cause the display to present the display object; 4) responding to the signal requesting a switch from

(Fed.Cir.2006) (holding that patentee must clearly disclaim the scope of otherwise broad claim language). In fact, the claim language itself supports IPI's position that the terms do not inherently contain a one-to-one restriction. For example claim I of the '5 12 patent requires "fust
play to cease presenting the first workspace and to begin presenting the second workspace; 5) causing a display to present a set of display objects; and 6) responding to the switch request signal by storing data indicating display characteristics of the display object before causing the display to cease presenting that set ofdisplay objects. The principal dispute surrounds what the specification discloses as the corresponding structure. IPI urges that the corresponding structure for all the "control means" limitations "is a pop up menu and its associated boxes and/or icons and their equivalents." Defendants urge that "control means" is govemed by IV'MS Gaming. Inc. v. Interna-

proposed structures reference box-diagrams and pseudocode describing various processes within the invention. However, as Defendants concede, none of the referenced diagrams are specifically directed at describing a "control means." Thus, the parties raise two issues.

For the purposes of discussion, claim I of the'412 patent calls for a "control means for accessing the first workspace data structure to cause the display to present the first workspace including the fust display object; the control means further being for accessing the second workspace data structure to cause the display to present the second workspace including the second display object." The specification describes this feature of the invention by describing the user's interaction with icons and pop-up menus within the computer program. For example, when describing Figures la and lb, the specif,rcation explains

In
contrast, Defendants' proposed structure for all the "control means" limitations is "procedures and data in the
display system as shown in Figs. 2-4 and 6-22, as specified, including the accompanying textual descriptions in the specifrcation, and Table I (at col. 2l)." While the figures and descriptions generally explain how a program might access or accomplish various tasks initiated by the user, the Figures do not describe what "control means" the user may interact with in order to initiate these processes. Further, the "structure" identified by Defendants encompasses far more than is encompassed by the "control means" limitation. For instance, Figure 2 describes
