  • Avago Technologies Limited, Avago Technologies US, Inc. and Avago Wireless IP (collectively “Avago”) in a litigation relating to bulk acoustic wave filters for use in cellular telephones. Many cellular telephones utilize BAW filters to differentiate between the various signals that a cellular telephone transmits and receives. The case is pending in the District of Arizona and includes 13 separate allegations of patent infringement, allegations of theft of trade secrets and claims against Avago for antitrust violations.
  • Avago Technologies in two other matters—one pending in the Northern District of California and another pending in the Eastern District of Texas. Both of these matters concern optical sensor and/or optical finger navigation technology which is often incorporated into the latest cellular telephones.
  • International Game Technology in a case where the Federal Circuit affirmed summary judgment in favor of IGT on patent infringement claims. The competitor Aristocrat's patent disclosed a means-plus-function claim directed to a novel type of slot machine and it claimed that IGT's slot machines infringed that patent. IGT argued on summary judgment that Aristocrat's patent was too indefinite to be valid because its specification failed to disclose sufficient structure. Both the district court and the court of appeals accepted our argument that Aristocrat's disclosure of a "microprocessor-based gaming machine with appropriate programming" was insufficient because it did not set forth an algorithm that would describe the required special purpose computer.
  • Abbott GmbH, in a case in which we persuaded the Federal Circuit to dismiss an appeal brought by our opponent from a district court decision upholding the validity of Abbott's patent. On remand to the Board of Patent Appeals and Interferences, the Board agreed with Mayer Brown that priority should be awarded to Abbott. The patent covers a novel protein that has substantial commercial potential because it plays a crucial role in fighting infections. The case is important because it is one of the first decisions addressing the question of whether a patent contains an adequate written description of a novel protein, which is a "biological" product, rather than a new drug.
