U.S. Supreme Court Remands Case to Federal Circuit to Review Patent Under Teva

May 4, 2015

Reading Time : 1 min

In the case, the plaintiff Azure Networks, LLC, sued Marvell in the Eastern District of Texas in 2011, alleging that Marvell’s products infringed Azure’s patent on Bluetooth technology. After the district court construed a particular patent term, Azure conceded that Marvell did not infringe the patent­in­suit and the court entered judgment in favor of Marvell in 2013. Azure appealed the construction to the Federal Circuit, and in November 2014, the Federal Circuit found in favor of Azure and reversed the district court’s construction.

Marvell filed a petition for writ of certiorari to the U.S. Supreme Court, arguing that the Federal Circuit reviewed the district court’s construction under the de novo standard of review, contrary to the Court’s Teva decision. Specifically, Marvell argued that the Federal Circuit made “factual findings contrary to those of the district court without identifying clear error.”

The U.S. Supreme Court issued a one­page order, remanding the case back to the Federal Circuit for further consideration in light of Teva.

CSR PLC v. Azure Networks, LLC, United States Supreme Court, No. 14­976.

The Federal Circuit recently affirmed a Patent Trial and Appeal Board decision finding claims that had been subject to an ex parte reexamination unpatentable. As a threshold issue, the court held that IPR estoppel under 35 USC § 315(e)(1) does not apply to ongoing ex parte reexaminations. Accordingly, the Patent Office did not err in continuing the reexamination after issuing final written decisions in co-pending IPRs.

The Federal Circuit recently denied a petition for a writ of mandamus that challenged the PTO Director’s reliance on “settled expectations” to discretionarily deny two inter partes review (IPR) petitions. In so doing, the court explained that, while it was not deciding whether the Director’s use of “settled expectations” was correct, the petitioner’s arguments about what factors the Director may consider when deciding whether to institute an IPR or post-grant review (PGR) are not generally reviewable and did not provide sufficient basis for mandamus review here.
