What is US7049320B2 (rolapitant) and what does it cover?
US7049320B2 is a U.S. patent application directed to chemical compounds and related subject matter that includes rolapitant. Rolapitant is the well-known neurokinin-1 (NK1) receptor antagonist used to help prevent chemotherapy-induced nausea and vomiting (CINV). The patent’s claims and descriptions focus on the specific chemical forms and variants tied to that therapeutic concept.
How does this patent relate to rolapitant as a drug?
Patents like US7049320B2 generally tie the “rolapitant” drug substance to one or more of these categories: the compound structure itself, specific stereochemistry or salt forms, and methods for making or using those compounds in therapeutic settings. For the user searching “US7049320B2 rolapitant,” the key connection is that the patent text is one source that ties rolapitant’s chemical identity and/or its claimed variants to an earlier priority filing date.
Why would someone search US7049320B2 specifically?
People commonly look up a specific patent number when they need one of the following:
- confirm whether a formulation or a generic candidate falls within a particular claimed chemical scope
- understand how early the invention dates are for rolapitant-related chemistry
- find prior art that may be relevant to later filings (e.g., improved synthesis, different salt forms, or related analogs)
How to check what parts of rolapitant are claimed in US7049320B2
If you’re using the patent to assess scope, the most important pages are usually:
- the claims section (what exactly is legally covered)
- the description and examples (how rolapitant and related compounds are defined)
- any definition of “compound,” “substituent,” salt forms, or stereochemistry in the specification
Where to find the patent text and claims
You can retrieve the full record (bibliographic details, claims, and specification) from public patent databases such as Google Patents by searching for “US7049320B2 rolapitant.”
If you paste the claims or the particular passage you’re looking at, I can help interpret what it likely covers (for example: whether it reads on rolapitant free base vs. a salt, or a specific stereochemical variant).
