523 IP LLC v. CureMD.Com
48 F. Supp. 3d 600
S.D.N.Y.2014Background
- Plaintiff 523 IP LLC alleges CureMD’s Patient Portal infringes the '523 Patent (Website Messaging System) with one asserted independent claim (Claim 31) alleged to be practiced by the Patient Portal.
- CureMD contends the Patient Portal does not infringe and that the '523 Patent is invalid; the court addresses both infringement and invalidity defenses.
- Parties filed cross-motions for summary judgment on infringement, non-infringement, and invalidity, plus motions to exclude expert/witness testimony.
- The court undertook claim construction, finding disputed terms in Claim 31 require construction, and provided its own constructions for several terms (e.g., plurality of message destinations, routing criteria, content processor, routing processor).
- The Court denied the parties’ summary judgment motions without prejudice to refiling, and granted in part and denied in part motions to exclude testimony; it also outlined further proceedings and conference dates.
- The opinion also details the invention and the CureMD Patient Portal, including how messages are created, stored, accessed, and routed within CureMD’s system.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Is the preamble of Claim 31 limiting? | No limiting effect; preamble merely states purpose. | Preamble limits the scope by tying to a web-based, internet-enabled system. | Preamble not limiting. |
| What does 'comprising' mean in Claim 31? | Comprising is nonexclusive; all six elements must be present. | Comprising includes but is not necessarily exclusive of other elements. | Comprising means including but not limited to; six elements are essential. |
| Does the term 'plurality of message destinations' include internal database recipients? | Yes, multiple recipients within a single system constitute a plurality. | No; destinations are external devices/entities, not internal recipients. | Message destinations are external devices; not a plural internal recipients within a single database. |
| What are the 'routing criteria' and who provides them? | Criteria can be broader than priority and may be provided by physician’s staff. | Criteria are priority-based, provided by the physician, acting as a stand-in for physician judgment. | Routing criteria are priority-based, provided by the physician, to route by importance. |
| What is meant by 'content processor' and its role? | Content processor functions differently than defense asserts; may include routing logic. | Content processor is a device that analyzes message content and matches to routing criteria. | Content processor means a device that analyzes content, matches against physician-provided routing criteria, and guides routing. |
| What is the court’s ruling on summary judgment and exclusion motions? | Summary judgment denied without prejudice to refiling; portions of testimony excluded but not wholly. |
