MEMORANDUM AND ORDER
This case is before the Court on the Motion to Dismiss Plaintiffs’ Second Amended Complaint (“Motion to Dismiss”) [Doc. # 38] filed by Defendants Grant Pri-deco, L.P. and Grant Prideco, Inc. (collectively “Grant Prideco”). Plaintiffs Hydril Compаny L.P. and Hydril U.K., Ltd. (“Hy-dril”) filed their Response [Doc. # 44] and *610 Grant Prideeo filed a Reply [Doc. # 45]. Based on the Court’s review of the full record and the application of governing legal authorities, the Court concludes that the Motion to Dismiss should be granted.
I. FACTUAL AND PROCEDURAL BACKGROUND
The factual background of this case was set forth fully in the Court’s Memorandum and Order entered June 22, 2005 (“June 22 Order”), and will not be repeated here. Briefly, Hydril manufactures аnd sells connections used to join segments of drill pipe in the drilling of oil and gas wells. Hydril U.K., Ltd., has sold finished drill pipe on one occasion. Grant Prideeo manufactures and sells both drill pipe and connections.
Grant Prideeo is the owner of United States Patent 6,244,631 (“the ’631 Patent”), which has been surrendered as part of a reissue proceeding beginning June 6, 2003. Hydril alleges that Grant Prideeo obtained the ’631 Patеnt through fraud and, therefore, its assertion of rights under that patent constitutes a violation of the antitrust laws as recognized in
Walker Process Equipment, Inc. v. Food Machinery & Chem. Corp.,
Hydril in this lawsuit asserted a breach of contract claim, a patent infringement claim involving a different patent, and the Walker Process claim. In the June 22 Order, the patent infringement claim was dismissed and Hydril was permitted to amend its Walker Process claim. Hydril filed its Second Amended Complaint, adding Hydril U.K., Ltd. as a Plaintiff. Defendants thеn moved to dismiss the Walker Process antitrust claim for a variety of reasons. Specifically, Defendants argue that Plaintiffs have failed to allege facts establishing that they have standing to assert the antitrust claim beсause they have not alleged an injury-in-fact, antitrust injury, or that Hydril is a proper antitrust Plaintiff. Defendants also argue that Hy-dril has failed to allege a viable Walker Process claim because they have not allegеd facts to show that Grant Prideeo engaged in the required level of activity to enforce the ’631 Patent. Defendants also asked the Court to decline to exercise supplemental jurisdiction over the pending breach of contract claim. The Motion to Dismiss has been fully briefed and it is now ripe for decision.
II. ANALYSIS
A. Standard for Motion to Dismiss
A district court may dismiss a complaint under Rule 12(b)(6) if it appears beyond doubt that the plaintiff can prove no set of facts consistent with his factual allegations which would entitle him to the requested relief.
Manguno v. Prudential Property and Cas. Ins. Co.,
“In considering a motion to dismiss for failure to state a claim, a district court
*611
must limit itself to the contents of the pleadings, including attachments thereto.”

B. “Enforcement” Requirement for a Walker Process Claim
Grant Prideco argues that Hydril’s
Walker Process
claim should be dismissed because,
inter alia,
Hydril has not alleged the required level of activity by Grant Prideco to enforce the ’631 Patent. The Federal Circuit has clearly held that “as a matter of Fedеral Circuit antitrust law, the standards ... for determining jurisdiction in a Declaratory Judgment Action of patent invalidity also define the minimum level of ‘enforcement’ necessary to expose the patentеe to a
Walker Process
claim for attempted monopolization.”

Unitherm Food Systems, Inc. v. Swift-Eckrich, Inc.,
In this case, Hydril alleges that Grant Prideco “has widely publicized the existence of the ’631 Patent to the industry in general.” Second Amended Complaint, ¶ 48. Hydril also alleges that Grant Pride-сo’s attorney wrote a letter to OMSCO, a drill pipe distributor, asserting that certain orders from OMSCO’s customers may violate the ’631 Patent. 2 Id. Hydril also alleges “on information and belief’ that Grant Prideco sent similаr letters to “others in the pipe and drilling industries.” Id.
Neither Hydril Company L.P. nor Hydril U.K., Ltd., alleges enforcement activity by Grant Prideco which would create an objectively reasonable apprehension that Grant Prideco might sue Hydril for *612 patent infringement. Initially, there is no allegation in the Second Amended Complaint that Grant Prideco has accused Hy-dril of infringing the ’631 Patent. The general advertisements mentioning Grant Prideco’s patent do not create a reasonable apprehension that Grant Prideco would sue Hydril. Similarly, the January 2003 letter to OMSCO does not contain an explicit threat or оther language which, under the totality of the circumstances, could create a reasonable apprehension on Hy-dril’s part that Grant Prideco might sue it for patent infringement. There is no allegation that any similar letters sent by Grant Prideco or its counsel to others in the pipe and drilling industry were more explicit or otherwise indicated Grant Pri-deco’s intention to enforce the ’631 Patеnt against Hydril or others. Additionally, there is no allegation that Grant Prideco engaged in any further activity to follow up on the January 2003 letter to OMSCO, or on any other similar letters to others.
Because Hydril hаs failed to allege enforcement activity by Grant Prideco which would create an objectively reasonable apprehension that Grant Prideco intended to enforce the ’631 Pаtent against Hydril, Plaintiffs have failed to allege the minimum level of enforcement necessary to state a Walker Process claim against Grant Prideco.
Hydril has been given two opportunities to amend its Complaint, most recently after Defendants’ explicit arguments that Hydril’s antitrust claim failed for various enumerated reasons. Hydril has had ample time to investigate its Walker Process claim, yet has failed to allege legally sufficient facts. The Court conсludes Hydril cannot state a claim upon which relief can be granted on the Walker Process claim, and that claim is dismissed.
C. Contract Claim
Hydril alleges that Grant Prideco breached a Merger Agreement entered into between the parties in 1997, pursuant to which the parties also entered into a licensing agreement referred to as the “Wedge Agreement.” The Court has only supplemental jurisdiction over this state law breach of contraсt claim.
The case is in its very early stages. Indeed, the Court has not yet entered a docket control order and discovery except as to Plaintiffs’ antitrust standing and antitrust injury has been stayed. Because the federal claims have been dismissed at such an early stage of the proceedings, under 28 U.S.C. § 1367(c)(3), the Court declines to exercise supplemental jurisdiction over Plaintiffs’ pendent statе law claim for breach of contract.
See Moore v. Willis Independent School Dist.,
III. CONCLUSION AND ORDER
Based on the foregoing, the Court concludes that Hydril has fаiled to allege the minimum level of patent enforcement activity necessary to support its Walker Process claim. The patent infringement claim was previously dismissed, and the Court declines to exercisе supplemental jurisdiction over the state law breach of contract claim. Accordingly, it is hereby
ORDERED that Defendants’ Motion to Dismiss [Doc. # 38] is GRANTED. Hy-dril’s Walker Process antitrust claim is DISMISSED with prejudice. It is further
*613 ORDERED that the breach of contract claim is DISMISSED without prejudiсe to Plaintiffs’ refiling the claim in state court. Plaintiffs should take note that the period of limitations for the dismissed state claim is tolled for an additional period of thirty (30) days after the date of this Order unless stаte law provides for a longer tolling period. 28 U.S.C. § 1367(d). The Court will issue a separate Final Order.
FINAL ORDER
For the reasons stated in the accompanying Memorandum and Order, it is hereby
ORDERED that Defendant’s Motion to Dismiss [Dоc. #38] is GRANTED and Hydril’s Walker Process antitrust claim is DISMISSED with prejudice. It is further
ORDERED that the breach of contract claim is DISMISSED without prejudice to Plaintiffs’ refiling the claim in state court. It is further
ORDERED that all prior ruling by the Court are herеby made final.
This is a final, appealable order.

Notes
. Because a
Walker Process
claim is aimed at removing patent law immunity from antitrust claims, the level оf enforcement required for a
Walker Process
claim is an issue associated with patent law and Federal Circuit law rather than Fifth Circuit law governs whether a patentholder has taken adequate steps to enforce the patent.
See Unitherm Food Systems, Inc. v. Swift-Eckrich, Inc.,
. The letter, attached as Exhibit 9 to the Second Amended Complaint, states that Grant Prideco believes the '631 Patent “may be relevant to” pending orders for certain drill pipe and does not mention Hydril. See Letter to OMSCO, Exh. 9 to Second Amended Complaint.
