Epclusa patent litigation lawsuit?

It sounds like you’re asking about the Epclusa (sofosbuvir/velpatasvir) patent litigation—usually meaning the kinds of lawsuits involving generic/competitor entry (often under the Hatch-Waxman framework in the US). I can help, but I need one detail first:

Which country/jurisdiction and what timeframe are you referring to (US, UK, EU, etc.)?

Also, are you looking for:

1. The specific case(s)/docket numbers, or
2. A summary of what the dispute was about (patents asserted, claims, typical outcomes), or
3. Status/outcome (e.g., settlement, approval triggered, injunctions)?

If you mean the US Epclusa patent litigation, tell me that and (if you have it) the generic company name (e.g., Teva, Mylan/Viiv, Sandoz, Glenmark, Hikma, etc.). Then I can summarize the relevant filings and decisions at a docket level.

• US or which jurisdiction?
• Approx. year(s)?
• Generic manufacturer (if known)?
• What you want: case list / summary / status
