RADER, Circuit Judge.
The United States District Court for the Southern District of New York granted summary judgment of noninfringement to Benetton Group SpA (Benetton).2 V-Formation, Inc. v. Benetton Group SpA, No. 01 Civ. 610(HB),
I.
U.S. Patent No. 5,873,584 (issued February 23, 1999) (the '584 patent)3 and the '466 and '143 patents, issued to Michael C. Wrike, all involve essentially the same technology: an in-line roller skate having a frame made up of several separate elements, wherein the frame sidewalls (to which the wheels аre mounted) are fastened to downwardly descending flanges formed from a toe plate and a heel plate. The toe and heel plates, in turn, fasten to the bottom of a skate boot. The patents refer to the distinct, separate, and interchangeable parts as "modular[ ]" skate construction. '466 patent, col. 2, ll. 40-44. The '143 patеnt issued from a continuation of the application that also produced the '466 patent. Thus, the specification and drawings of both patents are the same. Figure 5 shows a cross-sectional view of an assembled skate with the toe plate fastened to the boot by rivets and the sidewalls inserted into the cavities defined by the flanges of the toe plate. These sidewalls attach to the flanges with bolts.
This appeal involves the '466 patent's requirement that releasably attaches the sidewalls to the flange pairs as well as the '143 patent's toe and heel plate limitations. Claim 1 of the '466 patent includes the "releasably attaching" language:
An in-line roller skate, comprising:
a boot having a sole surface with toe and heel portions;
a frame, comprising;
a toe plate having an upper face and a lower face, said upper face being affixed to said sole surface toe portion, and two pair of spaced apart flanges extending downwardly from said toe plate lower face, each of said flange pairs defining a cavity therebetween;
a heel plate having an upper face and a lower face, said upper face being affixed to said sole surface heel portion, and two pair of spaced apart flanges extending downwardly from said heel plate lower face, each of said flange pairs defining a cavity therebetween;
first and second downwardly extending sidewalls having front and reаr upper portions, wherein said first sidewall is configured such that said rear upper portion is received into a corresponding one of said heel plate cavities and said front upper portion is received into a corresponding one of said toe plate cavities, and wherein said second sidewall is received into the other opposing said toe and heel plate cavities;
a plurality of fasteners for releasably attaching said first and second sidewalls to respective ones of said toe and heel plate flange pairs; and
a plurality of wheels rotatably mounted between said first and second sidewalls.
'466 patent, col. 9, ll. 1-30 (emphasis added). Claim 1 of the '143 patent includes the toe and heеl plate limitations:
An in-line roller skate, comprising:
a boot having a sole surface with toe and heel portions; and
a frame, comprising:
a toe plate having an upper surface affixed to said sole surface toe portion and a pair of spaced apart downwardly opening cavities, each of said toe plate cavities having an inner wall and an outer wall directly attached to a lower surface of said toe plate;
a heel plate having an upper surface affixed to said sole surface heel portion and a pair of spaced apart downwardly opening cavities, each of said heel plate cavities having an inner wall and an outer wall directly attached to a lower surface of said toe plate;
separate first and second downwardly extending sidewalls having front and rear upper portions, wherein said first sidewall is configured such that said rear upper portion is received into a corresponding one of said heel plate cavities and said front upper portion is received into a corresponding one of said toe plate cavities, and wherein said second sidewall is received into the other opposing said toe and heel plate cavities;
a plurality of fasteners for securing said first and second sidewalls within respective ones of said toe and heel plate cavities, each of said fasteners extending through one оf said sidewalls and a cavity inner wall; and
a plurality of wheels rotatably mounted between said first and second sidewalls.
'143 patent, col. 9, ll. 1-31 (emphases added).
On January 24, 2001, V-Formation initiated an action for infringement against Benetton for infringement of the '143, '466, and '584 patents. The original and amended complaints alleged that a number of different models of Benetton's in-line roller skates infringe claims of the patents in suit.
Benetton filed a motion for summary judgment, asserting noninfringement of the '466 and '143 patents and invalidity of the '584 patent. On September 10, 2002, the district court held a Markman hearing (Markman v. Westview Instruments, Inc.,

CLAIM CONSTRUCTION
This court must address the meaning of the claim term "releasably attaching" in claims 1 and 9 of the '466 patent. Claims 1 and 9 state: "a plurality of fasteners for releasably attaching said first and second sidewalls to respective ones of said toe and heel plate flange pairs." '466 patent, col. 9, ll. 25-27; col. 10, ll. 16-18 (emphasis added). The district court construed the term "releasably attaching" to mean that the fasteners "must permit the sidewalls to be easily removed and replaced." V-Formation, Inc.,
The intrinsic record in a patent case is the primary tool to supply the context for interpretation of disputed claim terms. Vitronics Corp. v. Conceptronic, Inc.,
In most cases, the best source for discerning this proper context is the patent specification wherein the patent applicant describes the invention. Metabolite,
The district court properly considered other intrinsic evidence to aid its construction. For instance, the district court considered U.S. Patent No. 5,549,310 (issued August 27, 1996) (the Meibock patent). The Meibock patent is prior art that was listed as a reference on the face of the '466 patent and in an Information Disclosure Statement. This prior art reference to Meibock is not extrinsic evidence. This court has established that "prior art cited in a patent or cited in the prosecution history of the patent constitutes intrinsic evidence." Kumar v. Ovonic Battery Co.,
The district court properly used the Meibock patent to set the context for its claim construction. The Meibock patent explains that the toe and heel plates are "permanently attached ... through the use of rivets or releasably attached through the use of fasteners such as screws or bolts." Meibock patent, col. 4, ll. 53-56 (emphases added); see also col. 5, ll. 22-25. The Meibock patent further explains: "Each fastener is shown in the preferred embodiment as a screw and retainer; however, any suitable releasable fastening device could be used. In alternative embodiments, a more permanent fastener such as a rivеt could also be used." Id. at col. 5, ll. 54-58. Thus, the district court correctly concluded: "[The] Meibock patent provides evidence that rivets are considered by persons of ordinary skill to be permanent fasteners." V-Formation, Inc.,
As the district court noted, the Meibock patent uses "strikingly similar language" to the '466 and '143 patents to describe its in-line skate construction. Id. Fоr instance, the Meibock patent recites: "[T]he frame and the base of the boot are generally integrally molded as a single piece or are permanently fastened together by riveting or bonding." Col. 1, ll. 36-40. In addition, the Meibock patent explains that the permanent rivet or bonding structures "prevent[ ] a user from adjusting the location of the frame with respect to the boot or from removing and exchanging one set of frames for another set of frames of a different configuration ." Id. at col. 1, ll. 38-42. By comparison, the '466 and '143 patents state that rivets or high-strength adhesives may secure the wheel frame to the base of the boot. '466 patent, col. 5, ll. 13-16; '143 patent, col. 5, ll. 16-19. Consequently, this court agrees with the district court's conclusion that one skilled in the art would not consider rivets within the category of releasable fasteners.
Finally, the district court properly weighed this court's opinion in K-2 Corp. v. Salomon, S.A.,
In sum, this court affirms the district court's claim construction defining "releasably attaching" in claims 1 and 9 of the '466 patent to mean that the fasteners "must permit the sidewalls to be easily removed and replaced" аnd determining that "those skilled in the art would not consider rivets ... to fall within the category of releasable fasteners."
INFRINGEMENT OF THE '466 PATENT
Because the frame sidewalls of the Benetton categories 3 and 7 skates are fastened with rivets, claims 1 and 9 of the '466 patent are not literally infringed. Literal infringement requires that each and every limitation set forth in a claim aрpear in an accused product. Becton Dickinson & Co. v. C.R. Bard, Inc.,
The accused skates also do not infringe claims 1 and 9 of the '466 patent under the doctrine of equivalents. Infringement under the doctrine of equivalents occurs when a claimed limitation and the accused product perform substantially the same function in substantially the same way to obtain substantially the same result. See Warner-Jenkinson Co. v. Hilton-Davis Chem. Co.,
INFRINGEMENT OF THE '143 PATENT
V-Formation argues that a genuine issue of material fact precludes summary judgment on the presence of toe and heel plates in Benetton's category 7 skates (also referred to as Pro 44 skates in the briefs). V-Formation perceives this dispute in the disagreement between the Polk Declaration and the Thomas Addendum. To the contrary, the record shows no disagreement about the structure of Benetton's catеgory 7 skates. The diverging views of the two experts concern whether or not integrally molded flanges (as is the case of Benetton's category 7 skates) can satisfy the toe plate and heel plate limitations of the '143 patent. The district court properly determined that the claims (which require toe and heel plates with an upper surfаce affixed to the bottom portion of the skate boot) do not include the Benetton structure. Therefore, the district court correctly concluded that the Benetton category 7 skates do not infringe claims 1 and 7 of the '143 patent either literally, or under the doctrine of equivalents.
III.
In sum, this court affirms the district court's construction of the '466 pаtent's claim term "releasably attaching" and its conclusion that no genuine issue of material fact precludes summary judgment on the '143 patent. Therefore, this court affirms the district court's summary judgment of noninfringement.
COSTS
Each party shall bear its own costs.
AFFIRMED.
