899 F.3d 1316
Fed. Cir.2018Background
- Power Integrations (PI) filed four IPR petitions challenging claims of three Semiconductor Components patents, all with a June 4, 1997 priority date.
- PI relied on three alleged printed-publication references: (1) Mammano conference paper (1993), (2) SMP3 product data sheet (dated 7/91), and (3) Unitrode UC1828 data sheet (excerpt labeled 1995/1994).
- The PTAB denied institution for each petition, finding PI failed to show public accessibility of any referenced document before the priority date.
- The PTAB explained deficiencies: lack of evidence about conference audience/restrictions for Mammano; no indicia of public distribution or practice for SMP3; and ambiguous dissemination and post-publication labels/copyright for UC1828.
- PI sought rehearing; the PTAB denied rehearing with detailed opinions. PI then petitioned this court for writs of mandamus seeking review of the non-institution decisions.
Issues
| Issue | PI's Argument | SCIA's / PTAB's Argument | Held |
|---|---|---|---|
| Whether mandamus can be used to review PTAB non-institution decisions | Mandamus is appropriate to remedy alleged APA violations and inadequate reasoning by the PTAB | Section 314(d) bars appellate review of non-institution decisions; mandamus cannot circumvent that bar | Denied: mandamus unavailable because PI lacks a clear and indisputable right and the bar on review is dispositive |
| Adequacy of PTAB’s explanation under the APA (5 U.S.C. § 555(e)) | PTAB’s explanations were legally insufficient and not the product of reasoned decisionmaking | PTAB issued detailed 15–20 page decisions plus rehearing opinions that explained the bases for denial; the APA notice requirement is modest | Held: PTAB’s explanations were adequate; no clear APA violation shown |
| Whether PTAB applied incorrect standard for public accessibility of alleged printed publications | PTAB applied an overly rigid standard and improperly required definitive proof at institution stage | PTAB legitimately required evidence showing public accessibility sufficient to conclude likely unpatentability at institution | Held: Court refused to review substantive or procedural challenges that would amount to merits review barred by § 314(d) |
| Whether the facts alleged (declarations, date codes, labels) established public accessibility for prior-art purposes | PI argued declarations and date markings showed public availability pre-priority | PTAB found the evidence circumstantial/insufficient (no distribution info, no indicia of public access, unclear provenance) | Held: Court declined to disturb PTAB factfinding absent extraordinary circumstances; PI did not show such circumstances |
