Narrative Opinion Summary
The case involves a patent infringement lawsuit brought by NTP, Inc. against Research In Motion, Ltd. (RIM) concerning the BlackBerry system. NTP alleged that RIM's products infringed its patents related to integrating electronic mail systems with wireless networks. After a jury found in favor of NTP, awarding substantial damages and a permanent injunction against RIM, the case was appealed. Key legal issues included the interpretation of patent claim terms such as 'originating processor,' the territorial limits of U.S. patent law, and the distinction between system and method claims. The Federal Circuit upheld certain claim constructions and reversed the judgment on method claims due to the extraterritoriality of RIM's Canadian-based components. The court remanded parts of the case for further proceedings to assess potential prejudicial effects of erroneous jury instructions on certain claims. The judgment was affirmed in part, reversed in part, and remanded with instructions for the district court to reevaluate damages and the injunction based on the remaining valid claims.

Application: The court's claim construction focused on terms such as 'originating processor' and 'gateway switch,' impacting the determination of infringement.
Reasoning: Claim construction involves resolving disputed meanings and clarifying the technical scope of patent claims to assess infringement.
Evidentiary Exclusions and Abuse of Discretionsubscribe to see similar legal issues
Application: The appellate court upheld the district court's exclusion of certain testimonies and demonstrations, finding no abuse of discretion.
Reasoning: The appellate review applied the Fourth Circuit's abuse of discretion standard and found the district court acted within its discretion in these exclusions.
Jury Instruction and Prejudicial Errorsubscribe to see similar legal issues
Application: The court remanded the case to determine if erroneous jury instructions on claim construction affected the verdict, particularly related to the term 'originating processor.'
Reasoning: The court identified an erroneous jury instruction regarding the term 'originating processor,' raising the issue of whether the jury's verdict should be overturned.
Method Claims and Territorialitysubscribe to see similar legal issues
Application: The court determined that method claims require all steps to be performed within the U.S. for infringement to occur, affecting RIM's liability given its BlackBerry Relay's location in Canada.
Reasoning: A method requires each step to be conducted, and unlike a system, which can function collectively, a process cannot be said to occur 'within' the U.S. unless every step is performed domestically.
Patent Infringement Under 35 U.S.C. § 271subscribe to see similar legal issues
Application: The case concerned allegations of patent infringement by RIM, particularly focusing on whether the use and sale of its BlackBerry system infringed NTP's patents within the U.S., despite components being located in Canada.
Reasoning: Unauthorized use, sale, or offering of a patented invention within the U.S. constitutes patent infringement as per 35 U.S.C. 271(a).
System Claims and Component Locationsubscribe to see similar legal issues
Application: The jury found that system claims can be infringed even if a component, like RIM's BlackBerry Relay, is located outside the U.S., as long as the system is used within the country.
Reasoning: The location of RIM's Relay in Canada does not legally prevent the infringement of the asserted system claims.
