II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 6,636,965 - "Embedding Recipient Specific Comments in Electronic Messages Using Encryption," issued October 21, 2003
The Invention Explained
- Problem Addressed: The patent addresses the inefficiency of sending customized electronic messages to subsets of recipients within a larger group. Conventional methods required sending multiple, separate messages, which was inconvenient for the sender and consumed unnecessary network bandwidth. (Compl. ¶13; ’965 Patent, col. 1:15-42).
- The Patented Solution: The invention proposes a method for creating a single electronic message containing a "common message portion" for all recipients and one or more "comments" intended only for a select subset. (’965 Patent, Abstract). These comments are encrypted so they can only be accessed by authorized recipients. The system can operate in two primary ways: either by pre-decrypting the comment for an authorized recipient before transmission, or by sending the encrypted comment to all recipients along with an "icon or other prompt" which, when selected by an authorized user, triggers a security check and subsequent decryption. (’965 Patent, col. 2:1-10, Fig. 4).
- Technical Importance: This approach enabled a single-send workflow for personalized mass communication, streamlining the process for users and conserving system resources. (Compl. ¶14).
Key Claims at a Glance
- The complaint asserts infringement of at least independent claim 1. (Compl. ¶16).
- The essential elements of independent claim 1 are:
- creating an electronic message with a common message portion for a number of recipients;
- creating a comment to the common message portion that can be received only by a selected subset of recipients;
- determining the number of recipients and the selected subset by creating a first address list (for all recipients) and a second address list (for the subset);
- delivering the common message and the comment by encrypting the comment and transmitting both the common message and the encrypted comment to the recipients; and
- determining if a recipient is allowed to decode the encrypted comment by transmitting an icon or instruction with the message, and if the recipient selects it, determining if that recipient is on the second address list.
III. The Accused Instrumentality
Product Identification
The accused instrumentality is the "Sharpspring Smart Email" platform. (Compl. ¶16).
Functionality and Market Context
The complaint describes the Accused Instrumentality as a marketing automation tool that allows users to create and send personalized emails. (Compl. ¶6, p.6). It enables the creation of a base email message and the insertion of "dynamic content," such as text, images, or offers, that are displayed only to specific segments of the recipient list. (Compl. ¶¶ 18-19). Users define these segments by setting rules based on recipient data like city, country, or interests. (Compl. ¶20). A screenshot provided in the complaint shows a user interface for selecting lead fields such as "City" or "Company Name" to create a dynamic content rule. (Compl. ¶20, p.11).
IV. Analysis of Infringement Allegations
’965 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| creating an electronic message with a common message portion that is to be delivered to a number of recipients | The Accused Instrumentality creates a base/default portion of a marketing email. | ¶18 | col. 5:11-13 |
| creating a comment to said common message portion... wherein said comment can be received only by a selected subset of said number of recipients | The user creates "dynamic components" (e.g., text, images) that are only shown to a categorically differentiated subset of recipients. A screenshot illustrates a "common message" area and a separate "comment to common message" block. | ¶19, p.7 | col. 5:14-18 |
| determining said number of recipients and said selected subset by creating a first address list that specifies said number of recipients and creating a second address list that specifies said selected subset | The system creates a list of all recipients and a second list for a specific segment of differentiated users (e.g., based on city, country, interest). A provided visual shows a drop-down menu with various options available to select a subset from a list of recipients. | ¶20, p.11 | col. 5:19-23 |
| delivering said common message portion and said comment to said number of recipients by: encrypting said comment | The "dynamic components of the message" are allegedly encrypted. The complaint points to a screenshot showing conditional logic (e.g., #if, #elseif) in the email's code as evidence of this step. |
¶21, p.13 | col. 5:26 |
| transmitting said common message portion and said encrypted comment to said number of recipients | The system transmits the base message content along with the encrypted dynamic components to all selected recipients. | ¶22 | col. 5:24-26 |
| determining whether a particular recipient is allowed to decode said encrypted comment by transmitting an icon or instruction... and determining if said particular recipient has selected the icon or performed the instruction... | The system transmits a "button or a clickable link for a promo code" that is part of the dynamic content, and determines if the recipient has selected it to review the comment. | ¶23 | col. 5:27-34 |
Identified Points of Contention
- Scope Questions: A central dispute may concern the meaning of "encrypting". The complaint appears to equate the use of conditional logic (e.g., "#if"/"#else" statements) to selectively display content with the act of "encrypting" a comment. (Compl. ¶21, p.13). The court will have to determine whether this interpretation is consistent with the patent's disclosure, which also refers to passwords and security codes. (’965 Patent, col. 4:21-24).
- Technical Questions: The complaint alleges the creation of a "first address list" and a "second address list." (Compl. ¶20). A key question may be whether the Accused Instrumentality actually generates a discrete second list, or if it instead applies dynamic filtering rules to a single master list at the time of message transmission. The evidence of how the accused system technically operates will be critical.
- Scope Questions: It is a question for the court whether a "button or a clickable link for a promo code" (Compl. ¶23) constitutes an "icon or instruction" for the specific purpose of decoding an encrypted comment, as required by the claim. This may be particularly relevant given the applicant's reliance on this feature to distinguish prior art during prosecution. (Compl. ¶15).
V. Key Claim Terms for Construction
- The Term: "encrypting said comment"
- Context and Importance: The construction of this term appears central to the dispute. The Plaintiff’s theory seems to depend on "encrypting" being broad enough to cover the use of conditional logic in code to control content visibility. If the term is construed more narrowly to require a specific cryptographic process, the infringement allegation may be more difficult to sustain. Practitioners may focus on this term because the factual basis for infringement hinges on whether SharpSpring's dynamic content feature meets this limitation.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The Summary of the Invention describes the outcome of encryption as ensuring comments "cannot be read or heard by all recipients but only by the intended recipient(s)." (’965 Patent, col. 1:55-59). This functional language could support an interpretation focused on access control rather than a specific technical method.
- Evidence for a Narrower Interpretation: The detailed description repeatedly references the use of a "password or other security code" in connection with accessing the comment, which suggests a traditional cryptographic context. (’965 Patent, col. 2:5-7; col. 4:21-24). The abstract also links decryption to a password. This, combined with the prosecution history argument regarding an "encrypted comment" (Compl. ¶15), may support a narrower definition requiring more than just conditional display logic.
VI. Other Allegations
- Indirect Infringement: The complaint does not provide sufficient detail for analysis of indirect infringement. The allegations are framed as direct infringement by Defendant. (Compl. ¶16).
- Willful Infringement: The complaint does not allege willful infringement. It alleges only that Defendant had constructive notice of the ’965 patent. (Compl. ¶25).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the term "encrypting", as used in the patent, be construed to cover the use of conditional server-side logic ("#if"/"#else") to selectively display content, or does it require a formal cryptographic process as suggested by the patent’s references to passwords and security codes?
- A second key question will be one of technical implementation: does the accused platform's method of applying dynamic rules to a recipient database at the time of sending meet the claim limitation of "creating a first address list... and creating a second address list," or is there a functional and structural difference that places it outside the claim's scope?
- A final question will be one of claim interpretation in light of prosecution history: does a standard hyperlink or button within an email constitute the claimed "icon or instruction" for decoding a comment, particularly given the applicant’s statements to the patent office distinguishing prior art on this basis?
