MEMORANDUM OPINION

SUE L. ROBINSON, District Judge.

I. INTRODUCTION

Callaway Golf Company (“plaintiff’) filed this action against Acushnet Company (“defendant”) on February 9, 2006, alleging infringement of U.S. Patent Nos. 6,506,130 (“the '130 patent”), 6,503,156 (“the '156 patent”), 6,210,293 (“the '293 patent”), and 6,595,873 (“the '873 patent”) (collectively, “the Sullivan patents”). (D.I.l) Plaintiff alleged that defendant’s Titleist® Pro VI® brand golf balls embody the technology claimed in one or more claims of the asserted patents. (Id. at ¶¶ 17-21) The parties filed motions for summary judgment. (D.I.197, 200, 201, 213, 215) On November 20, 2007, the court issued its claim construction decision (D.I. 345) and issued its memorandum opinion on the summary judgment motions (D.I. 347), in which it granted plaintiffs motions for summary judgment of no anticipation and for breach of contract, denied defendant’s motions for summary judgment of invalidity and no breach of contract, and denied defendant’s motion for partial summary judgment that U.S. Patent No. 4,274,637 to Molitor (“Molitor '637”) was incorporated by reference into a particular piece of prior art. Prior to trial, defendant stipulated that its Pro VI® golf balls infringe claims 1, 4 and 5 of the '293 patent, claims 1-3 of the '156 patent, claim 5 of the '130 patent, and claims 1 and 3 of the '873 patent, and that its Titleist® Pro Vlx® and Pro VI*® golf balls infringe all of the foregoing claims, with the exception of claim 1 of the '293 patent. (D.I.367) A jury trial was held between December 5 and 14, 2007 on the issue of validity of each of the asserted claims, due to obviousness. The jury returned a verdict that each as *605 serted claim was valid but one—claim 5 of the '293 patent—which it found invalid. (D.1.399) Currently before the court are several motions: defendant’s motion for judgment as a matter of law (“JMOL”) or, in the alternative, for a new trial (D.I.409); plaintiffs motion for a permanent injunction (D.I.411); and defendant’s motion to stay any permanent injunction issued by this court pending appeal (D.I.440). The court has jurisdiction over these issues pursuant to 28 U.S.C. §§ 1331,1338(a) and 1400(b).

II. BACKGROUND

A. Technology and Patents at Issue

As discussed in the court’s previous opinion (D.I.347), this case involves golf ball technology. Golf balls are typically identified as two-piece or three-piece balls. Two-piece balls have a core, which is either solid or “wound,” and an outer layer. A core that is considered solid is made of rubber and can be one solid piece or multiple layers. A wound core is made of elastic windings wrapped around either a solid or liquid-filled center. Three-piece balls have an additional layer covering the core, so that the ball is characterized as having a core, an inner cover layer and an outer cover layer.

The challenge faced by golf ball designers has been to create a ball that is both capable of traveling great distances and of achieving the desired “feel,” or spin. Historically, balls would have to be very hard in order to achieve distance when struck by a fast-moving driver. To achieve spin, however, balls had to be softer so that they would better grip to the face of angled clubs such as irons. The patents at issue present “dual personality” balls that achieve a marriage of these diametrically-opposed objectives.

Michael J. Sullivan is the sole named inventor on each of the '130, '156, '293, and '873 patents in suit (collectively, the “Sullivan patents”). The Sullivan patents have substantially identical specifications. Each of the underlying (continuation) applications were filed in 1999 (the '293 patent) and 2001 (the '130, '156, and '873 patents); all claim priority to U.S. Patent Application No. 08/070,510, filed June 1, 1993. The Sullivan patents issued to Spalding Sports Worldwide, Inc. (“Spalding”) in April 2001 (the '293 patent) and in 2003.

The Sullivan patents each claim a multilayer golf ball comprising a core, an inner cover layer made of a low acid ionomer, and an outer cover layer made of polyurethane. 1 The claims differentiate between the hardness and thickness of these layers. Claim 1 of the '293 patent claims:

1. A golf ball comprising: a core; an inner cover layer having a Shore D hardness of 60 or more molded on said core, said inner cover layer having a thickness of 0.100 to 0.010 inches, said inner cover layer comprising a blend of two or more low acid ionomer resins containing no more than 16% by weight of an alpha, beta-unsaturated carboxylic acid; and an outer cover layer having a Shore D hardness of 64 or less molded on said inner cover layer, said outer cover layer having a thickness of 0.010 to 0.070 inches, and said outer cover layer comprising a relatively soft polyurethane material.

Claim 4 of the '293 patent is also an independent claim, which reads:

4. A multi-layer golf ball comprising: a spherical core; an inner cover layer having Shore D hardness of about 60 or more molded over said spherical core, *606 said inner cover layer comprising an ionomeric resin including no more than 16% by weight of an alpha, beta-unsaturated carboxylic acid and having a modulus of from about 15,000 to about 70,000 psi; and an outer cover layer having a Shore D hardness of about 64 or less disposed about said inner cover layer and defining a plurality of dimples to form a multi-layer golf ball, said outer cover layer comprising polyurethane based material.

Claim 5 of the '293 patent is dependant on claim 4, and also requires that the “inner cover layer has a thickness of about 0.100 to about 0.010 inches and said outer cover layer has a thickness of about 0.010 to about 0.070 inches, said golf ball having an overall diameter of 1.680 inches or more.” By way of contrast, claim 1 of the '156 patent claims:

1. A golf ball comprising: a core; an inner cover layer disposed on said core, said inner cover layer having a Shore D hardness of at least 60, said inner cover layer comprising a blend of two or more low acid ionomer resins, each containing no more than 16% by weight of an alpha, beta-unsaturated carboxylic acid; and an outer cover layer disposed on said inner cover layer, said outer cover layer having a Shore D hardness of about 64 or less, a thickness of from about 0.01 to about 0.07 inches, and comprising a polyurethane material.

Claims 2 and 3 of the '156 patent are dependant on claim 1. Claim 2 adds the limitation that the “outer cover layer has a thickness of from about 0.01 to about 0.05 inches”; claim 3 increases these same thickness ranges to “about 0.03 to about 0.06 inches.”

Claim 5 of the '130 patent reads as follows:
