Opinion

*966 DYK, Circuit Judge.

In this patent infringement case, Wireless Agents LLC (‘Wireless”) appeals from the district court’s denial of a preliminary injunction to prevent Sony Ericsson Mobile Communications (USA) Inc. (“Sony”) from selling the accused products. We affirm.

BACKGROUND

Wireless is the assignee of U.S. Patent No. 6,665,173 B2 (filed Dec. 20, 2000) (“the ’173 patent”), entitled “Physical Configuration of a Hand-Held Electronic Communication Device.” Claim 1, the sole independent claim of the ’173 patent, recites:

A hand-held, electronic computing device having a physical configuration comprising: a body portion;
a display portion pivotally coupled to the body portion;
a constantly visible display carried by the display portion;
an alphanumeric keyboard carried by the body portion;
wherein the alphanumeric keyboard is at least partially concealed by the display portion when not in use; and
wherein the display portion pivots relative to the body portion in a plane that is generally parallel with the alphanumeric keyboard.

’173 patent, col. 13, 11. 30-41 (emphasis added).

On February 10, 2005, Wireless sued Sony 1 alleging that Sony’s S700i and S710a mobile phones literally infringed claim 1 and several dependent claims. The accused phones have twelve keys — ten keys representing the numbers 0-9 as well as “ * ” and “# ” keys. Each letter of the alphabet is assigned to one of the keys representing the numbers 2 to 9. Thus, approximately 3-4 alphabetic characters are associated with each number key. To select the alphabetic characters, the user switches to text-entry mode and presses a numeric key repeatedly until the desired alphabetic character is selected. The accused phones are also equipped with predictive text software which uses a built-in dictionary to predict common words’ being entered by the user after a certain sequence of key presses.

On April 28, 2005, Wireless filed a motion for a preliminary injunction seeking to enjoin Sony from selling the accused products in the United States. The district court (Judge Sidney A. Fitzwater) denied Wireless’s motion, finding that Wireless had not demonstrated a likelihood of success on the merits of its infringement claim under the district court’s construction of the term “alphanumeric keyboard.” Wireless Agents, LLC v. Sony Ericsson Mobile Commc’ns AB, 390 F.Supp.2d 532, 540 (N.D.Tex.2005). The district court construed “alphanumeric keyboard” to mean an “input device having a QWERTY, FITALY, or Dvorak layout or any other alphanumeric layout that includes a substantially full set of alphabetic and numeric keys.” Id. at 538-39 (internal quotation marks omitted). The “QWERTY” layout is the standard keyboard arrangement which includes a key for each letter of the alphabet, and the “FITALY” and “Dvorak” layouts are other arrangements which also include a full set of keys. The district court concluded that “[t]he Sony devices do not have an ‘alphanumeric keyboard,’ as the term is properly construed.” Id. at 539. Wireless timely appealed. We have jurisdiction pursuant to 28 U.S.C. §§ 1292(a)(1) and 1292(c)(1).

*967 DISCUSSION

This appeal turns entirely on the correct construction of the term “alphanumeric keyboard.” We construe the term “alphanumeric keyboard” without deference to the district court’s claim construction. Free Motion Fitness, Inc. v. Cybex Intl, Inc., 423 F.3d 1343, 1347 (Fed.Cir.2005).

The scope of the term “alphanumeric keyboard” is not readily apparent from the face of the claim, and there is no common dictionary definition of this term. 2 However, the term “alphanumeric keyboard” “must be read in view of the specification, of which [it is] a part.” Phillips, 415 F.3d at 1315 (internal quotation marks and citation omitted). The specification is “the single best guide to the meaning of a disputed term.” Id. (internal quotation marks omitted). Here, it is clear to us, as it was to the district court, that an “alphanumeric keyboard’ is an input device having a QWERTY, FITALY, or Dvorak layout or any other alphanumeric layout that includes a substantially full set of alphabetic and numeric keys, and that it does not include a twelve-digit keypad.

First, the description of the invention in the “Summary of the Invention” section of the specification states:

The keyboard may be a keyboard with a layout such as the common “QWERTY” layout, but need not be limited to this particular layout. Other layouts may include the “FITALY” layout, the “Dvorak” layout or any other alphanumeric layout that includes a substantially full set of alphanumeric keys.

’173 patent, col. 5, 11. 6-11 (emphasis added). The description clearly depicts the claimed invention as having “the common ‘QWERTY’ layout” or “any other alphanumeric layout that includes a substantially full set of alphanumeric keys.” This description is not merely referring to a preferred embodiment; rather, as part of the “Summary of the Invention,” it is “commensurate with the invention as claimed.” 37 C.F.R. § 1.73 (2004). Therefore, to allow Wireless to claim a keyboard with less than a substantially full set of keys would injure the public’s right “to take the patentee at [his] word.” Honeywell Int’l, Inc. v. ITT Indus. Inc., 452 F.3d 1312, 1318 (Fed.Cir.2006).

Wireless argues that the specification cannot be used to define the term “alphanumeric keyboard” because at the end of the specification the ’173 patent contains the following boilerplate language:

Although the invention has been described with reference to a particular embodiment, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments as well as alternative embodiments of the invention will become apparent to persons skilled in the art.... It is therefore contemplated that the appended claims will cover any such modifications or embodiments that fall within the scope of the invention.

’173 patent, col. 13, II. 20-28. We see nothing in this language that contradicts our reading of the specification.

Second, the specification explicitly references the disadvantages of keypads that have only twelve digits, such as the accused device. For example, in describing the disadvantage of the mobile phone twelve-digit keypad, the specification states:
