What patents cover Lovastatin (Teva), and how do you find them?
Lovastatin is available as a generic medicine, so the relevant patent questions usually come down to which patents are listed in the U.S. FDA Orange Book for each specific Teva marketing product (including strengths and dosage forms). The most direct way to identify “Lovastatin Teva patents” is to search the FDA’s Orange Book by the product’s active ingredient (lovastatin) and the specific Teva product label (for example, tablet strengths). Orange Book listings typically include patent numbers and the “drug substance” and “drug product” patent categories used for regulatory exclusivity/patent challenges. [1]
If you want a narrower answer (specific patent numbers and expiration dates for “Teva”), you need to know which Teva product you mean (strength and dosage form), because Orange Book listings are tied to specific NDA/ANDA products rather than the company alone. [1]
Do patents still block generic lovastatin in the U.S.?
Because lovastatin has long been on the market as a generic in the U.S., it’s common that many older patents have expired. Whether anything is still listed as “active” for a particular Teva lovastatin ANDA depends on the Orange Book status for that specific product (and whether any later-listed patents remain in force). The Orange Book is the source used to determine whether a listed patent is still expiring and whether it’s tied to a specific ANDA product. [1]
How long do these patents/exclusivities last (and why the dates matter)?
For U.S. products, the key dates you’ll see are usually patent expiry dates and, separately, exclusivity periods (like those related to new drug application approvals or changes). Orange Book listings provide the patent numbers and the associated expiration or “estimated” expiration information, which is what people typically mean when they ask about “Lovastatin Teva patents.” [1]
Are there lawsuit filings or patent challenges tied to Teva’s lovastatin?
If there are unexpired Orange Book patents for Teva’s specific ANDA product, they may be implicated in Hatch-Waxman patent litigation between brand holders and generic applicants. Those disputes are usually not the same as the Orange Book list itself; they are court proceedings that can confirm or contest patent validity and timing. To connect “Teva lovastatin patents” with litigation, you normally match the Orange Book patents for the relevant Teva ANDA to later court records and dockets. [1]
What if you meant a patent by a company name rather than an FDA product?
If your goal is “What patents does Teva own for lovastatin?” that’s different from “What patents does the FDA list for Teva’s lovastatin product.” Orange Book is about regulatory listings tied to specific ANDAs/NDA references; patent databases (USPTO or commercial patent search tools) are about ownership/inventorship and claim scope. You’d search by assignee (Teva) and the keyword “lovastatin,” then map the patent publication/expiration to any Orange Book listings if needed. [1]
What I need from you to give exact patent numbers
Right now, “Lovastatin Teva patents” is too broad to return a precise set of patent numbers without knowing which Teva product you mean. Share either:
- the Teva product strength/dosage form (e.g., lovastatin 20 mg tablets), or
- the FDA NDA/ANDA number, or
- the Orange Book listing entry you’re looking at,
and I can then tell you which Orange Book patents are associated with that specific product and what their listed expiration information is. [1]
