II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 8,155,887 - Computer Visualized Drug Interaction Information Retrieval

The Invention Explained

  • Problem Addressed: The patent's background section describes the difficulty and inefficiency of manually consulting literature to check for adverse interactions among multiple prescribed or over-the-counter drugs, noting that it is not reasonable to presume that a drug dispensary will always consult the requisite texts ('887 Patent, col. 1:22-49).
  • The Patented Solution: The invention provides a computer-implemented method and system to automate this process. The system is described as acquiring imagery of multiple substances (e.g., pills), identifying each substance based on its visual characteristics, retrieving data for each identified substance from a database, and then correlating that data to display any potential drug-drug interactions ('887 Patent, Abstract; col. 2:60-65). Figure 1 illustrates this workflow, from imaging individual drugs (110A, 110B) to generating a "Drug Interaction Report" (150) ('887 Patent, Fig. 1).
  • Technical Importance: This technology sought to provide a faster and more systematic alternative to manual, text-based research, aiming to reduce the risk of human error in identifying potential adverse drug interactions ('887 Patent, col. 2:1-6).

Key Claims at a Glance

  • The complaint asserts infringement of at least independent claims 1 and 10.
  • Independent Claim 1 (Method):
    • Acquiring, for each of multiple different substances, imagery of at least one external characteristic of a physical body of the substance;
    • Determining an identity of each substance based on the acquired imagery;
    • Retrieving drug interaction data for each substance using the determined identity;
    • Correlating, using a processor, the interaction data for at least two of the substances; and
    • Displaying the correlated drug interaction data.
  • Independent Claim 10 (Computer Program Product): This claim recites a computer-usable storage medium with code to perform the same five essential steps outlined in Claim 1.
  • The complaint does not explicitly limit its allegations to these claims, preserving the option to assert others.

III. The Accused Instrumentality

Product Identification

The complaint names the "Epocrates application" and the "epocrates.com" website as the Accused Instrumentalities (Compl. ¶27).

Functionality and Market Context

The complaint alleges that these products are used for "identifying and providing information about drugs" (Compl. ¶27). The complaint provides a visual from Google Maps showing an Athenahealth office in Austin, Texas, to support its allegation that Defendant maintains a regular and established place of business in the district (Compl. ¶8, Fig. 1). However, the complaint does not provide specific details or visuals concerning the user interface or the precise operational workflow of the accused application or website.

IV. Analysis of Infringement Allegations

The complaint alleges that the Accused Instrumentalities infringe at least Claims 1 and 10 of the ’887 Patent and incorporates by reference a claim chart (Exhibit B) that was not attached to the publicly filed document (Compl. ¶¶31, 37). The following chart summarizes the infringement theory for Claim 1 based on the narrative allegations available in the complaint. The allegations for Claim 10 are substantively identical.

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
acquiring, for each of multiple different substances, imagery of at least one external characteristic of a physical body of the substance; The complaint alleges the Accused Instrumentalities provide a system for identifying drugs, which necessarily involves acquiring information corresponding to the drug. The complaint does not specify how this "acquiring imagery" step is performed by the accused products. ¶27, ¶31 col. 5:40-44
determining an identity of each of the multiple different substances based upon the at least one external characteristic from the acquired imagery; The Accused Instrumentalities are alleged to perform the function of "identifying... drugs," which corresponds to this claim element. ¶27, ¶31 col. 5:45-48
retrieving drug interaction data for each of the multiple different substances using the determined identities; The Accused Instrumentalities allegedly provide "information about drugs," which the complaint contends includes retrieving drug interaction data. ¶27, ¶31 col.5:49-52
correlating, using a processor, drug interaction data for at least one of the multiple different substances with at least one other of the multiple different substances; and The complaint’s infringement theory rests on the assertion that the Accused Instrumentalities provide drug interaction information, which would require a correlation step. ¶17, ¶31 col. 5:53-57
displaying the correlated drug interaction data. The Accused Instrumentalities are alleged to provide information to the user, which would constitute displaying the correlated data. ¶17, ¶27 col. 5:58-59

Identified Points of Contention

  • Scope Questions: A central dispute may arise over the meaning of "acquiring... imagery of at least one external characteristic of a physical body." The question is whether this language, which the patent specification links to cameras and visual markings ('887 Patent, col. 3:17-26, Fig. 2), can be construed to read on a system where a user identifies a drug by typing its name or selecting it from a textual or symbolic list.
  • Technical Questions: A factual question will be what evidence demonstrates that the Accused Instrumentalities perform the "acquiring imagery" step as required by the claim. The complaint does not provide screenshots or a technical description of the products' user interface to show how a user inputs drug information.

V. Key Claim Terms for Construction

  • The Term: "acquiring, for each of multiple different substances, imagery of at least one external characteristic of a physical body of the substance"
  • Context and Importance: The construction of this term appears central to the dispute. If the term is construed to require the capture of a new visual image of a physical object (e.g., a pill), infringement will depend on whether the accused products include such a feature. If construed more broadly to include selecting a pre-existing image or icon, the infringement analysis would change significantly. Practitioners may focus on this term because of the potential mismatch between the patent's camera-focused embodiments and the likely text-based input of the accused web application.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The claim language itself does not explicitly limit "acquiring imagery" to an act of photographic capture with a camera. A party could argue that retrieving a stored image from a database upon a user's selection meets the plain meaning of "acquiring imagery."
    • Evidence for a Narrower Interpretation: The specification's detailed description and figures appear to favor a narrower construction. The system is repeatedly described in the context of a "camera" (e.g., col. 3:17-18, col. 4:11-13) capturing an image of a substance to detect "identifying content disposed on" it, such as a "pill marking or code" (col. 3:23-26). Figure 2 explicitly depicts a "Camera" (220) as a core system component.

VI. Other Allegations

  • Indirect Infringement: The complaint alleges induced infringement, asserting that Defendant distributes "product literature and website materials" that instruct and encourage end-users to operate the Accused Instrumentalities in a manner that directly infringes the ’887 Patent (Compl. ¶34).
  • Willful Infringement: The complaint alleges that Defendant has had knowledge of its infringement "at least as of the service of the present complaint" (Compl. ¶29) and has continued to infringe despite this knowledge (Compl. ¶34). This allegation appears to support a claim for post-filing willfulness only, as no facts suggesting pre-suit knowledge are pleaded.

VII. Analyst’s Conclusion: Key Questions for the Case

  1. A core issue will be one of definitional scope: can the claim phrase "acquiring... imagery of at least one external characteristic of a physical body," which is described in the patent's embodiments in the context of camera-based capture, be construed to cover the text-based or menu-driven drug selection methods likely employed by the accused Epocrates software?
  2. An associated key evidentiary question will be one of factual proof: assuming the claim is not construed so broadly, what evidence can Plaintiff provide to demonstrate that the accused application and website actually perform a function that meets the "acquiring imagery" limitation as claimed in the ’887 Patent? The complaint itself does not contain such evidence.
