Narrative Opinion Summary
The case involves a patent infringement dispute between Modavox, Inc. as the plaintiff and Tacoda, Inc. as the defendant, focusing on two patents related to web page functionality enhancement. The central issue is the construction of several claim terms, particularly 'function' and 'embedded,' within the patents. The court evaluates the parties' proposed definitions, ultimately finding both parties' interpretations of 'function' lacking and requesting extrinsic evidence for a more precise definition. The court interprets 'embedded' as requiring the code module to be physically contained within the web page's HTML code, aligning with its ordinary meaning. Additionally, the court addresses the doctrine of claim differentiation, emphasizing that it cannot extend claims beyond permissible limits. The term 'command' is agreed upon by both parties as an order or instruction. The court defines 'service response' broadly, encompassing various acceptance conditions beyond those outlined in dependent claims. The court instructs the parties to submit extrinsic evidence for 'function' and schedules further proceedings to resolve the remaining issues. The outcome hinges on these interpretations, significantly impacting the scope of the patents and the parties' claims of infringement.
Legal Issues Addressed

Application: The parties agree on defining 'command' as an order, instruction, or direction, with no further clarification needed.
Reasoning: Regarding the term 'command,' both parties have reached a consensus that it means an order, instruction, or direction, which does not require additional clarification.
Definition of 'Service Response'subscribe to see similar legal issues
Application: The court interprets 'service response' to encompass various acceptance conditions beyond the metaphors specified in a dependent claim.
Reasoning: The term 'service response' in Claim 1 is not confined to the three responses outlined in Claim 8; it may encompass other forms beyond those specified.
Doctrine of Claim Differentiationsubscribe to see similar legal issues
Application: The court holds that the doctrine of claim differentiation cannot extend claims beyond their permissible limits or override construction principles that necessitate a narrower interpretation.
Reasoning: The presumption regarding patent claims is rebuttable and can be challenged by the written description or prosecution history.
Interpretation of 'Embedded'subscribe to see similar legal issues
Application: The court interprets 'embedded' as meaning physically contained within the web page's HTML code, rejecting a broader interpretation.
Reasoning: The interpretation that a code module must be physically present—rather than merely referenced—is upheld, as it aligns with the ordinary meaning of 'embedded' and the context of the claim.
Interpretation of 'Function'subscribe to see similar legal issues
Application: The court finds that both parties' definitions of 'function' are inadequate, and a broader interpretation may be warranted based on the patent's language.
Reasoning: The court criticizes the plaintiff's definition for being overly broad and notes that 'function,' as used in the patent, is a noun representing a desirable feature, not an action like 'targeting.'
Patent Claim Constructionsubscribe to see similar legal issues
Application: The court is tasked with construing the claim terms at issue using intrinsic evidence, except for the term 'function' which requires extrinsic evidence.
Reasoning: The court is prepared to construe five claim terms using only intrinsic evidence, with the exception of the term 'function,' which will require extrinsic evidence.
