II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 8,155,887 - Computer Visualized Drug Interaction Information Retrieval
- Issued: April 10, 2012
The Invention Explained
- Problem Addressed: The patent's background section identifies the challenge of manually checking for potentially harmful interactions among multiple drugs, a process that is prone to error and impractical in many settings given the volume of available medications and known interactions (’887 Patent, col. 1:36-50).
- The Patented Solution: The invention proposes a computer-implemented system that automates this process. It works by first acquiring images of multiple physical substances (e.g., pills), identifying each substance by its visual features, retrieving pre-existing interaction data for the identified substances from a database, and then correlating and displaying any potential interactions between them (’887 Patent, Abstract; col. 3:9-36). This allows for a rapid assessment of interaction risks without manual look-ups (’887 Patent, col. 3:5-8).
- Technical Importance: This automated approach sought to improve patient safety by making drug interaction checks more efficient and reliable than manual consultation of medical literature (’887 Patent, col. 1:45-50).
Key Claims at a Glance
- The complaint asserts independent Claim 1 (Compl. ¶8).
- Essential elements of Claim 1 include:
- 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 of the multiple different substances based upon the at least one external characteristic from the acquired imagery;
- retrieving drug interaction data for each of the multiple different substances using the determined identities;
- 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
- displaying the correlated drug interaction data.
- The complaint does not explicitly reserve the right to assert dependent claims.
III. The Accused Instrumentality
Product Identification
The complaint does not identify any specific accused product, method, or service by name (Compl. ¶9).
Functionality and Market Context
The complaint alleges that Defendant "employs the method covered by Claim 1 of the ’887 patent" but provides no specific details regarding the functionality or operation of any accused instrumentality (Compl. ¶9). Instead, it refers to an "infringement analysis at Exhibit B," which was not filed with the complaint (Compl. ¶9). The complaint does not provide sufficient detail for analysis of the accused instrumentality's functionality or market context.
IV. Analysis of Infringement Allegations
No probative visual evidence provided in complaint.

Identified Points of Contention
- Evidentiary Questions: The primary question is what evidence Plaintiff possesses to support its allegations. The complaint's infringement theory is entirely dependent on an external exhibit that was not provided, leaving no factual basis in the pleading itself to assess how the accused method allegedly operates or maps to the claim elements (Compl. ¶9).
- Technical Questions: Without details on the accused system, it is unknown how it allegedly performs key steps. For example, what evidence demonstrates that Defendant's system "acquires imagery" of a "physical body," as opposed to receiving user-inputted drug names? What evidence shows it performs a "correlation" step, rather than merely displaying individual drug information side-by-side?
V. Key Claim Terms for Construction
The Term: "at least one external characteristic of a physical body of the substance"
Context and Importance: This term is foundational to the claimed invention, as it defines the raw input for the identification process. The viability of the infringement claim depends on whether the feature used by the accused system for identification qualifies as an "external characteristic" of a "physical body."
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim language itself is broad, not limiting the "characteristic" to any particular type (e.g., text, color, shape). The specification refers generally to "identifiable content disposed on the different drugs" (’887 Patent, col. 2:67-col. 3:1).
- Evidence for a Narrower Interpretation: The specification provides a specific example of the characteristic as a "pill marking or code" (’887 Patent, col. 3:24-25). A defendant may argue that this example limits the scope of the term to textual or symbolic imprints, rather than more general features like pill color or shape.
The Term: "correlating... drug interaction data"
Context and Importance: This term defines the core analytical step of the invention. The dispute will likely center on what level of processing is required to meet the "correlating" limitation. Practitioners may focus on this term because if it merely means looking up pre-computed pairs in a database, its scope is broad; if it requires a more dynamic, real-time analysis, its scope may be narrower.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent describes retrieving "known drug interactions" and determining "relative interactions between the different imaged substances by locating references in the interaction data for each of the imaged substances to others" (’887 Patent, col. 3:30-33; col. 5:46-49). This could support a reading that simply cross-referencing substances against a database of known interaction pairs constitutes "correlating."
- Evidence for a Narrower Interpretation: The term "correlating" could be argued to imply more than a simple lookup, potentially requiring some form of logical synthesis or analysis of different data points to generate a result, rather than just retrieving a pre-existing result. However, the specification provides limited support for a narrower definition beyond the database lookup model.
VI. Other Allegations
- Indirect Infringement: The complaint alleges active inducement under 35 U.S.C. § 271(b), asserting that Defendant had "full knowledge of the ’887 patent" and "specifically intended for its customers to infringe" by using the accused systems (Compl. ¶10, ¶12). No specific facts, such as references to user manuals or marketing materials, are provided to support this allegation.
- Willful Infringement: The complaint alleges willful infringement based on the assertion that infringement continued "at least since Defendant first learned about the ’887 patent" (Compl. ¶13). The complaint does not specify when or how this alleged knowledge was acquired.
VII. Analyst’s Conclusion: Key Questions for the Case
- A central issue will be one of evidentiary sufficiency: given that the complaint makes only conclusory allegations of infringement by referring to an unprovided exhibit, a key question is whether Plaintiff can produce evidence demonstrating that Defendant’s system actually performs each step of the claimed method, particularly the initial step of acquiring imagery from a physical substance.
- The case may also turn on a question of definitional scope: can the term "external characteristic," which the patent illustrates with a "pill marking or code," be construed broadly enough to read on the specific identification method used by the accused system, the details of which are not yet known?
