Final answer:
The Nebraska court's jurisdiction over Hop-On rests upon the extent of Hop-On's contacts with Nebraska, determined by Nebraska's long-arm statute and due process. Factors like contract performance and economic impact may establish minimum contacts. The distribution and online presence might also affect jurisdiction.
Step-by-step explanation:
The Nebraska court's jurisdiction over Hop-On in a case of copyright infringement, conversion, and unjust enrichment depends on the application of the state's long-arm statute and principles of due process. A court has personal jurisdiction if the defendant has sufficient minimum contacts with the forum state, and the exercise of jurisdiction is reasonable and just. In this case, factors such as the existence of a contract between a Nebraska and a Nevada corporation, the performance of contractual obligations within Nebraska, and the impact of the alleged wrongdoing on a Nebraska corporation, could potentially establish the required minimum contacts. Additionally, the distribution of phones incorporating the disputed design in California and operation of a website might contribute to establishing jurisdiction if it can be shown that these activities indicate an intention to serve the Nebraska market. However, specifics of Nebraska's long-arm statute and case law would need to be considered to determine whether jurisdiction is proper.
