Via an insurance / breach of contract case in the United States District Court for the Western District of Pennsylvania:

Although the Court has found that Hotaling’s contacts  [*18] with Pennsylvania are sufficient to support the Court’s exercise of personal jurisdiction, it does not follow automatically that venue in this district is proper. As the language of Section 1331(a) makes clear, the focus in assessing venue is not on the "defendants’ ‘contacts’ with a particular district, but [on] the location of those’ ‘events or omissions giving rise to the claim.’" Cottman Transmission Sys. v. Martino, 36 F.3d 291, 294 (3d Cir. 1994). In order to establish specific jurisdiction, a plaintiff must show only that at least one contact on the part of the Defendant related to the Plaintiff’s claim. O’Connor, 496 F.3d at 318 (citing Helicopteros, 466 U.S. at 414). The inquiry with respect to proper venue, however, is significantly more circumscribed, requiring a showing that a substantial part of the events or omissions giving rise to the claim occurred in the district. 28 U.S.C. § 1331(a)(2).

Pullman Fin. Corp. v. Hotaling, 2008 U.S. Dist. LEXIS 48359 (W.D.Pa. June 24, 2008). Defense motion for transfer of venue granted.
