When does Vyvgart Hytrulo’s patent expire?

Vyvgart Hytrulo (efgartigimod-hyaluronidase) is a newer formulation of efgartigimod, and patent expiry depends on the specific patent family and the country where protection is being granted. The most reliable way to pinpoint the actual expiry date is to look up the exact U.S. (and/or EU/other) patent entries for “efgartigimod-hyaluronidase” and then identify the latest expiration date in that family.

Why the answer can differ by location (and by which patent you mean)

Even for the same product, different patents can cover different aspects (for example, formulation, method of use, or specific compound variants), and each has its own expiry date. That means the “last-to-expire” patent (the one that blocks generic or biosimilar competition the longest) can be later than earlier patents.

What to check next if you need the exact “last” expiry date

If you tell me the country (U.S. vs. EU vs. another market) and whether you mean:
- the earliest patent expiry, or
- the last/most restrictive expiry in the portfolio,
I can help you interpret the relevant dates from the patent listing.
