Short Summary
The PTAB denied Cipla Limited's IPR petition against Gilead Sciences regarding patent 11,744,802, citing the advanced stage of parallel district court litigation and lack of compelling merits.
Detailed Summary
In an Institution Decision, the Patent Trial and Appeal Board (PTAB) denied Cipla Limited’s request to institute Inter Partes Review (IPR) against Gilead Sciences for U.S. Patent No. 11,744,802 B2. The denial was based on discretionary grounds under 35 U.S.C. § 314(a). Key factors weighed included the proximity of the district court trial date (October 6, 2025) to the statutory deadline and the significant overlap in issues between the two proceedings. Furthermore, the Board found that the petition did not present compelling merits.
