District Court's Markman Ruling Has No Preclusive Effect On PTO Reexam
Client Alert | 1 min read | 08.24.07
The Federal Circuit, in In Re Trans Texas Holdings Corp., (No. 2006-1559, -1600, Aug. 22, 2007), affirms a Board's Reexamination decision that found that each of the claims of two related patents were invalid under 35 U.S.C. § 103(a) as obvious over the prior art. The Court rejects the appellant's argument that the Board should have given preclusive effect to a district court's Markman order, which had construed the claims in their favor in a prior litigation. The Court holds that issue preclusion is not warranted because the PTO was not a party to the earlier litigation, and as a result, did not have a "full and fair opportunity" to litigate the claim construction issues.

District Court Grants Preliminary Injunction Against Seller of Gray Market Snack Food Products
On November 12, 2025, Judge King in the U.S. District Court for the Western District of Washington granted in part Haldiram India Ltd.’s (“Plaintiff” or “Haldiram”) motion for a preliminary injunction against Punjab Trading, Inc. (“Defendant” or “Punjab Trading”), a seller alleged to be importing and distributing gray market snack food products not authorized for sale in the United States. The court found that Haldiram was likely to succeed on the merits of its trademark infringement claim because the products at issue, which were intended for sale in India, were materially different from the versions intended for sale in the U.S., and for this reason were not genuine products when sold in the U.S. Although the court narrowed certain overbroad provisions in the requested order, it ultimately enjoined Punjab Trading from importing, selling, or assisting others in selling the non-genuine Haldiram products in the U.S. market.
