What is US 7,049,320 (rolapitant)?
US 7,049,320 is a U.S. patent that relates to rolapitant, an NK1 (neurokinin-1) receptor antagonist developed for use in preventing chemotherapy-induced nausea and vomiting (CINV). The patent number itself identifies the specific intellectual-property document in U.S. patent records.
Who holds the patent, and what does it cover?
To answer “who holds it” and “what claims it covers,” I need the patent record text (assignee/applicant and the abstract/claims). With only “US 7049320 rolapitant” provided, I can’t reliably extract those details without the patent’s metadata or a link to the patent page.
Is this patent still active or has it expired?
Patent status depends on filing dates, any term adjustments, and whether later continuations were granted. The expiration date can be calculated from the application timeline, but I need the application/priority dates (or the USPTO/Google Patents link) to provide an accurate expiration estimate.
What do people search this patent for?
Search intent around a specific patent number is usually one of these:
- finding the assignee (company/institution) and the filing timeline,
- confirming whether the claims cover rolapitant formulations, dosing, or combination regimens,
- checking whether the patent blocks generic or biosimilar entry for rolapitant,
- locating the abstract and claims to understand what is protected.

- what the invention is (from the abstract),
- what’s actually claimed (from the claims),
- the assignee/owner,
- and whether it appears expired or still enforceable based on the timeline.
