What is US 8,080,663 about (cevimeline)?
US 8,080,663 is a U.S. patent record tied to cevimeline (a drug used for salivary gland function in conditions like Sjögren’s-related dry mouth). The patent number indicates the listed invention and claims are protected in the U.S., but the specific claim scope (method, composition, formulation, or use) depends on the patent text.
If you’re trying to identify the exact relevance—such as whether it covers the drug product itself, a specific formulation, dosing regimen, or a particular manufacturing approach—you’ll need the patent’s “claims” and “abstract” sections.
Has the cevimeline patent US 8,080,663 expired, and what does that mean for generic entry?
Whether and when generics can enter turns on multiple things: patent term, any patent extensions or adjustments, and whether additional patents in the same “family” still block approval or marketing. Even after a patent number expires, other listed patents can still delay generic competition.

How can I confirm whether US 8,080,663 blocks a specific cevimeline generic?
To figure out if a specific generic is blocked by US 8,080,663, check:
- Whether the generic’s product is covered by the patent claims (not all patents tied to a drug cover every formulation or use).
- Whether the generic is relying on a carve-out or design-around.
- Whether the patent is listed for the branded reference product in the Orange Book (if applicable).

What to look for inside the patent record (so you can tell what it actually protects)
When you open the patent text for US 8,080,663, focus on:
- The abstract (what problem the invention addresses)
- The independent claims (the core legal protection)
- The dependent claims (narrow variations within the core claims)
If you tell me what you need (for example, “Is this a composition patent or a method-of-use patent?” or “Does it relate to cevimeline hydrochloride tablets vs capsules?”), I can help interpret what the patent is likely protecting based on those sections.
