Opinion

ORDER

JOSEPH A. DiCLERICO, JR., District Judge.

Insight Technology Inc. brings a patent infringement action against SureFire, LLC, alleging infringement of United States Patent Number 6,574,901 (“the '901 patent”). The '901 patent is titled “Auxiliary Device for a Weapon and Attachment Thereof’ and relates generally “to an auxiliary (e.g. illumination) device for a weapon and, more particularly, to attaching an auxiliary device to a weapon.” Insight accuses SureFire’s X200 WeaponLight, and related products, and SureFire’s Military, Millenium, and Nitrolon series tactical lights (“MMN-type”) of infringing claims of the '901 patent. Insight moves for partial summary judgment on infringement, and SureFire objects.

Background

Insight accuses SureFire’s X2Q0-type and its MMN-type tactical lights of infringing independent Claim 1 of the '901 patent and its dependent claims 2, 5-13, 17, 21-24, and 28. Insight accuses the MMN-type lights of infringing claims 25 *116 and 27. Claim 1 of the '901 patent provides as follows:

An auxiliary device for use with a weapon, the auxiliary device comprising:
a housing:
at least one source of illumination located within the housing;
a first structural member extending upward from a first side of the housing and extending along at least a portion of a length of the first side of the housing;
a second structural member extending upward from a second side of the housing, wherein the second side of the housing is located opposite to the first side of the housing, and wherein the second structural member extends along at least a portion of a length of the second side of the housing such that it is substantially parallel to the first structural member, and wherein both the first and second structural members are substantially parallel to a central, longitudinal axis extending along a length of the housing; and
a spring-biased mechanism extending across and along a top surface of the housing, and wherein the spring-biased mechanism is configured to be biased in a direction normal to the top surface of the housing.

Claim 2 addresses the same auxiliary device but it comprises an illuminator. The other asserted claims add specific limitations to Claim 1.

For purposes of claim construction, the parties disputed a list of terms and phrases used in the '901 patent. The court issued a claim construction order on February 28, 2006, 2006 WL 519672. For purposes of the summary judgment motion, only the meaning of the phrase “a spring-biased mechanism ... configured to be biased in a direction normal to the top surface of the housing” is at issue. The court construed the phrase “biased in a direction normal to the top surface of the housing” to mean “forced by a biasing spring or biased in a direction that is perpendicular to the top surface of the housing ... although no specific angle of perpendicularity is required.”

Standard of Review 1

Summary judgment is appropriate when “the pleadings, the discovery and disclosure materials on file, and any affidavits show that there is no genuine issue as to any material fact and that the movant is entitled to judgment as a matter of law.” Fed.R.Civ.P. 56(c). The party seeking summary judgment must first demonstrate the absence of a genuine issue of material fact in the record. See Celotex Corp. v. Catrett, 477 U.S. 317, 323, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986). A party opposing a properly supported motion for summary judgment must present competent evidence of record that shows a genuine issue for trial. See Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 256, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). All reasonable inferences and all credibility issues are resolved in favor of the nonmoving party. See id. at 255, 106 S.Ct. 2505.

When the party moving for summary judgment also bears the burden of proof at *117 trial, the movant “cannot prevail unless the evidence that he provides on that issue is conclusive.” E.E.O.C. v. Union Independiente de la Autoridad de Acueductos y Alcantarillados de P.R., 279 F.3d 49, 55 (1st Cir.2002) (internal quotation marks omitted). Evidence is conclusive if the moving party provides enough record evidence that even when taken in the light most favorable to the nonmovant, no reasonable jury could find against the movant, and the nonmovant fails to provide sufficient evidence to raise a genuine issue of material fact. L & W, Inc. v. Shertech, Inc., 471 F.3d 1311, 1318 (Fed.Cir.2006).

Discussion

Insight asserts, with support from the declaration of its founder and president, Kenneth Solinsky, who is also one of the named inventors of the '901 patent, that the 200X-type and the MMN-type products literally infringe claims of the '901 patent. For purposes of summary judgment, SureFire does not dispute that its accused products are auxiliary devices for use with a firearm or that the products include a housing and a source of illumination within the housing. SureFire contends, however, that material factual disputes exist as to whether the accused products include a spring-biased mechanism as claimed in the '901 patent, whether the adapter used by the MMN-type lights precludes infringement, and whether the X200-type lights include first and second structural members as required by Claim 1 of the '901 patent.

Infringement is a factual question. Bd. of Regents of the Univ. of Tex. Sys. v. BENQ Am. Corp., 533 F.3d 1362, 1367 (Fed.Cir.2008). To prove literal infringement, the patentee must show that every limitation of the asserted patent claim is present in the accused product. Pfizer, Inc. v. Teva Pharms., USA, Inc., 429 F.3d 1364, 1376 (Fed.Cir.2005). Infringement must be proven by a preponderance of the evidence. Cross Med. Prods., Inc. v. Medtronic Sofamor Danek, Inc., 424 F.3d 1293, 1310 (Fed.Cir.2005).

A. Spring-Biased Mechanism

Each of the asserted claims includes the limitation of “a spring-biased mechanism ... configured to be biased in a direction normal to the top surface of the housing.” In his declaration, Solinsky States with reference to a color-coded picture that each of SureFire’s accused devices “includes a spring-biased mechanism (colored blue and yellow) that extends across and along a top surface of the housing.
