MEMORANDUM OPINION

SUE L. ROBINSON, District Judge.

I. INTRODUCTION

Presently before the court are six motions brought in this patent infringement action involving Robert Bosch LLC (“Bosch”) and Pylon Manufacturing Corp. (“Pylon”) relating to Bosch’s United States Patent Nos. 6,292,974 (“the '974 patent”), 6,675,434 (“the '434 patent”), and 6,944,905 (“the '905 patent”) (collectively, the “Bosch patents”). (D.I. 1) The procedural history of this action is complex and is described in greater detail below. Pending before the court are: (1) Bosch’s renewed motion for judgment as a matter of law (“JMOL”) or, in the alternative, for a new trial (D.I. 309); (2) Pylon’s renewed motion for JMOL concerning the non-infringement of claims 1, 5 and 13 of the '434 patent (D.I. 316); (3) Pylon’s renewed motion for JMOL or, in the alternative, motion to amend or alter the judgment concerning the invalidity of claim 13 of the '434 patent (D.I. 318); (4) Pylon’s renewed motion for JMOL or, in the alternative, for a new trial regarding the invalidity of the '905 patent (D.I. 320); (5) Bosch’s motion for leave to file a sur-reply in opposition to Pylon’s motion for JMOL or, in the alternative, motion for a new trial regarding the invalidity of the '905 patent (D.I. 351); and (6) Bosch’s motion for a permanent injunction (D.I. 311).

*387 II. BACKGROUND 1

A. Patents in Suit

This case involves the refinement of several aspects of beam blade technology found in the Bosch patents, resulting in wiper blades that allow for better performance, visibility and safety on the road. The '974 patent, entitled “Glass Wiper Blade For Motor Vehicles,” teaches a beam blade that prevents “lift-off’ issues by deflecting wind up and over the blade through the use of a flexible spoiler on top of the support element. This deflection counteracts any “lift-off’ tendency by creating additional downward force along the length of the wiper blade at higher speeds. ('974 patent at col. 1:58-2:3, 2:11-15) Claim 1, which is representative of the invention of the '974 patent, claims

[a] wiper blade for windows of motor vehicles, comprising a curved, band-shaped, spring-elastic support element which distributes a pressure applied by a wiper arm and has a concave and a convex surface which defines corresponding planes; an elongated rubber-elastic wiper strip placeable on a window to be wiped and mounted to said concave surface of said support element which faces the window, substantially longitudinally parallel to said concave surface; a connection device provided for a wiper arm and arranged directly on a convex side of said support element; and a component which is separate from said wiper strip and is mounted directly to the convex surface of said support element so as to form a leading-edge face extending in a longitudinal direction of the support element and forming, as seen crosswise to its longitudinal extension, an acute angle with a plane which extends parallel to a plane formed by said convex surface.

The subject matter of the '434 patent, entitled ‘Wiper Blade For The Glass Surfaces Of Motor Vehicles With An Elongated, Spring-Elastic Support Element,” addresses innovations with respect to wiper blade end caps. End caps serve a safety function, preventing injury to those who handle the wiper blades by covering the often sharp ends of the support element. ('434 patent at col. 1:63-65) However, end caps can adversely affect the elasticity of the spring element which, in turn, disrupts the wiper strip’s even distribution of pressure upon the windshield. (Id. at col. 1:46-50) The '434 patent discloses end caps that are used to maintain the integrity of the wiper blade without adversely ■affecting the elasticity of the beam. (Id.) Claim 1 claims

[a] wiper blade for windows or other glass of motor vehicles, having an elongated, spring-elastic support element, on whose side toward the window or glass an elongated, rubber-elastic wiper strip that can be placed against the window or glass is located parallel to the longitudinal axis, and on the side of the support element remote from the window or glass, in the middle portion of the support element, a device for attaching a *388 driven wiper arm is disposed, the two ends of the wiper blade each being covered by a respective termination part in the region of the support element, characterized in that the termination part has a base body, located on the side of the support element remote from the window and bracing itself on the wiper blade, which base body is provided with hook-like extensions that cross the support element on both of its long sides and engage the side of the support element toward the window from behind; that at least one detent shoulder pointing toward the other end portion is disposed on each of the two end portions of the support element, and a counterpart shoulder present on the termination part is associated with the detent shoulder; and that at least one of the two shoulders and/or at least one of the two extensions is elastically deflectable.

(Id. at col. 7:41-65)

The '905 patent is entitled “Wiper Blade For Cleaning Screens In Particular On Motor Vehicles.” Although existing separately from the '974 patent family, the '905 patent discloses the structure of a spoiler that could be used in conjunction with the invention of the '974 patent. The spoiler taught by the '905 patent includes two diverging legs, with an attack surface embodied on the outside of one leg, allowing for a reduction in both weight and material costs. ('905 patent at col. 1:55-64) The '905 patent also describes wiper blades that incorporate end caps. (Id. at col. 7:60-8:21) Claim 13 of the '905 patent, which is at issue in this case, reads:

13. A wiper blade for cleaning windows, comprising:
