Opinion

MOORE, Circuit Judge.

Southco, Inc. appeals from the orders of the United States District Court for the Eastern District of Pennsylvania granting summary judgment of noninfringement of U.S. Patent Nos. 5,851,095; 6,280,131; and 6,468,012, granting summary judgment of noninfringement of U.S. Trademark Nos. 2,478,685 and 3,678,153, and denying a motion to strike an expert declaration. For the reasons set forth below, we affirm-in-part, reverse-in-part, vacate-in-part, and remand.

BACKGROUND

Southco sued Fivetech Technology Inc., alleging that Fivetech’s captive screws infringed various claims of the asserted patents and trademarks. A captive screw is a particular type of fastener for attaching two parts. The patents at issue claim particular types of captive screws that contain, among other things, a hollow piece, called a ferrule, a screw within the ferrule, and a knob secured to the head of the screw. The ferrule is configured to attach to the first part and is configured so that the screw does not fall out of the captive screw assembly while the captive screw is used to join the two parts.

The district court found that the accused products did not infringe any of the asserted claims because the products did not meet limitations requiring that the knob and ferrule be “attached,” that the screw have an “annual chamfer,” that the knob and ■ screw be “rigidly secure,” and that “material from [the] knob [fill the annular] chamfer.” The district court found that the accused products did not infringe Southco’s trademarks because Fivetech had not used the accused mark in commerce in the United States. Southco ap *683 peals. We have jurisdiction over this appeal under 28 U.S.C. § 1295(a)(1).

Discussion

We review the ultimate question of claim construction de novo and factual findings underlying the ultimate question for substantial evidence. See Teva Pharms. USA, Inc. v. Sandoz, Inc., — U.S. -, 135 S.Ct. 831, 841-42, — L.Ed.2d - (2015). Here, we review the district court’s claim constructions de novo because the intrinsic evidence determines the proper construction. Id. at 841. Under Third Circuit law, we review a grant of summary judgment de novo. Keurig, Inc. v. Sturm Foods, Inc., 732 F.3d 1370, 1372 (Fed.Cir.2013) (citing Nicini v. Morra, 212 F.3d 798, 805-06 (3d Cir.2000) (en banc)). Summary judgment is appropriate if “the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed.R.Civ.P. 56(a). At the summary judgment stage, we credit the non-movant’s evidence and draw all justifiable inferences in its favor. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 255, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986).

I. '095 and '131 patents

The district court granted summary judgment that Fivetech did not infringe claims 1-15 of the '095 patent or claims 1-15 of the '131 patent. It concluded there was no literal infringement based on its construction of the claim term “attached.” It concluded that there was no infringement under the doctrine of equivalents because the all elements test was not met and the accused product “uses a washer, which is entirely absent from the Southco patents.” Southco, Inc. v. Fivetech Tech., Inc., No. 10-1060, 2012 WL 246253, at *5-6 (EJD.Pa. Jan. 25, 2012) ('095 and '131 Order).

Figure 3 of the '095 and '131 patents shows a captive screw having a screw head (24), threaded shaft (22), hollow knob (30) and hollow ferrule (50). '095 patent col. 3 11. 3-8. Figure 2 shows the same captive screw when the knob (30) is in the extended position and the threaded shaft (22) is retracted. Id. col. 2 11. 21-24. In this position, the first annular flange (35) on the knob (30) and the second annular flange (56) on the ferrule (50) are in contact. Id. col. 511. 32-34.

The parties agree that claim 1 of the '095 patent is representative of the asserted claims of the '095 and '131 patents. Claim 1 recites:

1. A captive screw attachable to a panel, for attaching the panel to a surface, the surface having a threaded hole, the captive screw comprising:
a) a screw having a head portion and a threaded shaft,
c) a thin-walled, cylindrical, hollow knob comprising a first end having an annular top surface, a second end, and an inner surface;
e) a hollow ferrule having a first end and a second end through which the threaded shaft slides, ... and a threaded shaft captivation means, said threaded shaft captivation means adjacent the second end, wherein the second end of the ferrule is slidably and rotatably attached to the knob such that when the threaded shaft is in a retracted position, the threaded shaft captivation means prevents the ferrule and the knob from separating and when the threaded shaft is in an extended position, the flat, annular bottom surface of the head portion of the screw is in contact with the second end of the ferrule.

'095 patent col. 6 11. 2-32 (emphasis added).

A. Construction of “Attached”

The district court concluded that the asserted claims of the '095 and '131 patents, which recite that the knob and ferrule are slidably and rotatably “attached,” require that the knob be directly connected to the ferrule. The district court did not rely on extrinsic evidence in construing *686 the claims. '095 and '131 Order, 2012 WL 246253, at *4 n. 7.

We agree with the district court’s construction. Southco is correct that the ordinary meaning of “attached” includes both direct and indirect attachment. However, the claim requires more&emdash;namely that the ferrule and knob are attached “such that when the threaded shaft is in a retracted position, the threaded shaft captivation means prevents the ferrule and the knob from separating.” '095 patent col. 6 11. 25-29. An indirect attachment would not satisfy the limitation that the “the threaded shaft captivation means prevents the ferrule and the knob from separating” because if the ferrule and knob are already separated&emdash;i.e., not directly attached&emdash;the threaded shaft captivation means cannot prevent them from separating.

Nothing in the specification compels a construction of “attached” that includes indirect attachment.
