MEMORANDUM
Destiny Tool (“Destiny”), SGS Tools Company (“SGS”), and Dauphin Precision Tool, LLC (“Dauphin”), all manufacture and sell carbide end mills, precision cutting heads that have many industrial uses. SGS and Dauphin (collectively, “Defendants”) own U.S. Patent No. 5,049,009 (“the '009 patent”), which claims an improved rotary cutting end mill. In 2004, Defendants filed suit in the Northern District of Ohio alleging that Destiny’s products infringed the '009 patent. After the Ohio district court in 2006 granted Defendants’ motion to dismiss their suit with prejudice, Destiny filed suit in the Northern District of California accusing Defendants of malicious prosecution and abuse of process under state law, as well as monopolization and attempted monopolization under the Sherman Act. Destiny appeals from the district court’s dismissal of all four claims. Defendants cross-appeal from the district court’s resolution of subsidiary preemption, statute of limitation, and res judicata issues. We have jurisdiction under 28 U.S.C. § 1291, and we affirm.
I
We review de novo a dismissal for failure to state a claim pursuant to Federal Rule of Civil Procedure 12(b)(6). Madison v. Graham,
A
The parties dispute whether the law of California or the law of Ohio applies to Destiny’s claims of malicious prosecution and abuse of process. When a federal court exercises supplemental jurisdiction over state law claims, it applies the choice-of-law rules of the forum state. Paracor Fin., Inc. v. Gen. Elec. Capital Corp.,
As all the parties acknowledge, a true conflict exists between the laws of California and Ohio with respect to claims of malicious prosecution and abuse of pro
Which state’s law governs therefore depends on which state’s interests would be more severely impaired if its law is not applied. Destiny relies on Bernhard v. Harrah’s Club,
As Destiny admitted below that it has not pleaded the additional elements of malicious prosecution and abuse of process required by Ohio law, the district court properly dismissed these claims under Rule 12(b)(6). Nor did the district court abuse its discretion in failing to provide Destiny an opportunity to amend the complaint, as “it is clear that the complaint could not be saved by any amendment.” Rubke v. Capitol Bancorp, Ltd.,
B
The district court dismissed Destiny’s antitrust claims on the basis that, under
The Sixth Circuit has not specifically addressed whether an antitrust claim is a mandatory counterclaim in prior patent infringement litigation. See P & M Servs., Inc. v. Gubb, No. 07-12816,
In determining whether a counterclaim is compulsory under Rule 13(a), the Sixth Circuit generally applies the “logical relationship” test. Sanders v. First Natl. Bank & Trust Co. in Great Bend,
Destiny nonetheless argues that it did not have sufficient knowledge of Defendants’ misdeeds to include an antitrust counterclaim in its Ohio answer. However, it did not seek to amend its counterclaim to include antitrust allegations until more than a year after the Ohio action was filed. We refuse to now reward Destiny for sleeping on its rights.
II
In their cross-appeal, Defendants argue for dismissal of Destiny’s claims based on
Ill
We AFFIRM the district court’s order granting Defendants’ motion to dismiss Destiny’s complaint. Each party is to bear its own costs.
