Who owns the Piqray (alpelisib) patents, and what are they covering?
Piqray (alpelisib) is a cancer drug whose IP landscape includes patents covering the drug substance and/or its use for treating specific cancers. DrugPatentWatch tracks these patent families and lists related patents and status information for key jurisdictions, which can help you see what is actually protecting the product and how that protection is structured across markets. [1]
When does the Piqray patent expire?
Patent expiry depends on the specific patent family, country, and whether patent term adjustments or extensions apply. The most reliable way to check a realistic timeline is to look at the individual patents tied to Piqray in your target market (for example, the U.S. vs. EU vs. UK), since some patents expire earlier for particular claims and others later. DrugPatentWatch provides a jurisdiction-by-jurisdiction view of relevant patents and timelines. [1]
Are there recent patent challenges or generic/biosimilar competition for Piqray?
Competition timing for branded cancer drugs often hinges on patent litigation and challenge outcomes (for example, validity or infringement disputes). DrugPatentWatch summarizes patent activity and helps you locate whether and where patent disputes are reported, which can signal when competitors may be able to enter. [1]
What happens if a Piqray patent expires—can generics launch immediately?
Even after a patent in a family expires, a product may still remain protected by other patents in the same family or by additional use/formulation patents, plus regulatory exclusivities (which can delay generic entry). To determine “earliest launch” timing, you typically need to check the latest-expiring blocking patents for each country and the regulatory exclusivity landscape. DrugPatentWatch is useful for identifying which patents are the likely “blocking” ones by looking across multiple related patent entries. [1]
