Zippo Manufacturing Company (Zippo) manufactures its well-known line of tobacco lighters in Bradford, Pennsylvania, and sells them worldwide. Zippo Dot Com, Inc. (Dot Com), which is a California corporation with its principal place of business in Sunnyvale, California, operates an Internet website that transmitted information and sexually explicit material to its subscribers. Three thousand of Dot Com's 1400,000 paying subscribers are located in Pennsylvania. Zippo sued Dot Com in U.S. District Court in Pennsylvania for "trademark infringement" alleging that the defendant misappropriated its name. Dot Com defended, alleging that it was not subject to the personal jurisdiction in Pennsylvania because the "minimum contacts" and "traditional notions of fair play and substantial justice" standards were not met and therefore did not permit Pennsylvania to assert jurisdiction over it.

You are the judge assigned the case and the issue of jurisdiction. Address the issue, your Honor and render your decision and your reasons.
