SanDisk v. Lexar Media (N.D. Cal.). Assisted with the representation of SanDisk, a manufacturer of computer flash memory, in a patent infringement suit against Lexar Media. SanDisk alleged that Lexar’s flash-memory storage cards infringed SanDisk’s patent.

Crocs, Inc. v. International Trade Commission, et al. (ITC, Fed. Cir.) Assisted in a patent infringement suit in which we represented Crocs in a suit brought against several competitors before the International Trade Commission (ITC). The complaint contended that the competitors’ products infringed two of Crocs’ patents, one utility patent and one design patent. Ultimately, the ITC ruled that some of the competitors had infringed the utility patent, but that the utility patent was invalid for obviousness. The ITC further ruled the design patent valid but not infringed, and determined that Crocs had not satisfied the technical prong of the industry requirement under Section 337 for the design patent. In Crocs’ subsequent appeal to the U.S. Court of Appeals for the Federal Circuit, our attorneys secured a reversal of the ITC’s finding that the Crocs patents were obvious. After a comparison of the shoes in question, the court found infringement, and also reversed the ITC’s finding of no domestic industry on the design patent.

Intel v. Broadcom (D. Del.). Assisted the firm is representing Broadcom, a major semiconductor manufacturer, in a patent infringement action brought by Intel. The five patents at issue involved video compression, networking technology, and semiconductor packaging. Intel sought monetary damages and an injunction sufficient to put Broadcom out of business.
