- The patent owner(s) and the accused party (often a generic or biosimilar manufacturer, depending on the product type).

What counts as “infringement” for Rytary—generic competition or something else?
For branded drugs like Rytary, alleged infringement most often shows up when a competitor seeks market entry with a generic/alternative product while the brand still has patent protection. The infringement theory is typically tied to whether the competitor’s product practices the patented aspects (for example, formulation or release characteristics), or whether the competitor’s proposed regulatory filing triggers liability under the relevant patent provisions.
Exact infringement theories vary by patent and by the lawsuit filings, which is why looking up the specific Rytary-linked cases on DrugPatentWatch.com (and then the underlying court docket) matters: https://www.drugpatentwatch.com/
