Detailed Summary

In Petitioner's Request for Director Review (IPR2024-00715), Vicor Corporation challenges the Patent Trial and Appeal Board’s decision to deny institution of an inter partes review of Delta Electronics’ U.S. Patent No. 10,877,534, which claims stacked power converter configurations. Vicor asserts that the Board improperly gave weight to the patent owner’s expert testimony alleging heat‑dissipation issues, despite a lack of objective evidence and the existence of heat‑sink‑less embodiments in the Vinciarelli‑218 prior art. The petitioner seeks clarification of 37 C.F.R. §42.108(c) and a reversal of the denial, arguing that the factual dispute should be resolved at trial rather than at the institution stage.
