FAQs
How broad are the chemical claims in Patent 9,320,862?
They define a specific compound with particular substituents, making them broad within structural limits but narrow against unrelated chemical classes.
Does the patent cover formulations or just the compound?
Both; claims include formulations, salts, and therapeutic methods involving the compound.
Are there active patent challenges against this patent?
No specific challenges are publicly documented for this patent, but future validity actions are possible given the crowded patent landscape.
Can the patent be designed around?
Yes, by modifying structural elements outside the scope of claims or developing alternative therapeutic mechanisms not covered.
When does the patent expire?
Expected around 2035, given standard 20-year patent terms from filing dates, unless extensions or adjustments apply.
