II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 6,330,549 - “Protected Shareware”
- Patent Identification: U.S. Patent No. 6,330,549, “Protected Shareware,” issued December 11, 2001 (’549 Patent). (Compl. ¶7).
The Invention Explained
- Problem Addressed: The patent describes the challenge of preventing computer software "piracy" and enforcing payment for software distributed through informal channels like "shareware," where traditional physical copy protection is impractical and unpopular. (’549 Patent, col. 1:8-10, 1:31-36).
- The Patented Solution: The invention proposes a method where "protective code" embedded within a computer program controls its functionality based on a "digitally signed messaging protocol." (’549 Patent, Abstract; col. 2:40-42). The program's advanced features remain inhibited until it receives an "authorization message" that has been digitally signed by an authorized party (e.g., a "billing agency") using a secret key. The program itself contains the corresponding public key to verify the message's authenticity before enabling the features. The solution also includes an "integrity self-checking routine" to ensure the protective code itself has not been tampered with. (’549 Patent, col. 2:42-55).
- Technical Importance: The described system provided a technical framework for monetizing software that could be freely distributed, creating a mechanism to tie program functionality to a verifiable and secure authorization process. (’549 Patent, col. 2:18-24).
Key Claims at a Glance
- The complaint asserts at least independent claim 1. (Compl. ¶13).
- The essential elements of independent claim 1, a method claim, are:
- Inhibiting a functional feature of a computer program from running on a user computer until it receives a digitally signed authorization message.
- Providing the program’s embedded protective code with access to a public checking key associated with the secret signing key.
- Running an integrity self-check over the computer program to confirm it is in an "anticipated state."
- Communicating the authorization message to the user computer.
- Applying the public checking key to the authorization message to authenticate it.
- Enabling the functional feature if the message is authenticated and the integrity check confirms the program is in the anticipated state.
- The complaint does not explicitly reserve the right to assert dependent claims, but the prayer for relief requests judgment of infringement of the ’549 patent generally. (Compl. ¶A, p. 4).
III. The Accused Instrumentality
Product Identification
- The accused product is Defendant's website, https://www.novartis.com/. (Compl. ¶10).
Functionality and Market Context
- The complaint alleges that the standard operation of Defendant's website, specifically its use of the Transport Layer Security (TLS) 1.2 protocol to establish a secure HTTPS connection, constitutes infringement. (Compl. ¶13). The alleged infringing functionality involves preventing unauthorized access to the website's features until a secure connection is established via an exchange of digitally signed certificates between the user's computer (client) and the website's server. (Compl. ¶13(a)). The complaint does not contain allegations regarding the website's specific commercial importance or market position beyond identifying it as the accused product. No probative visual evidence provided in complaint.
IV. Analysis of Infringement Allegations
’549 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| (a) inhibiting via the embedded protective code at least one functional feature of the computer program from running on a user computer until the user computer receives an authorization message that is digitally signed by an authorized party using a secret signing key... | Preventing access to the website's features until a secure Hypertext Transfer Protocol (HTTPS) connection is established, which requires receipt of the server's digitally signed certificate. | ¶13(a) | col. 8:51-56 |
| (b) providing the embedded protective code with access to the public checking key... | The HTTPS connection process provides access to the public checking key via the signed certificate sent from the server to the client. | ¶13(b) | col. 8:57-58 |
| (c) running an integrity self-check over the computer program to confirm that the computer program is in an anticipated state, the integrity self-check being embedded in the computer program... | An HMAC (Hashed-based message authentication code) process within the TLS 1.2 protocol is used to confirm the integrity of messages between the client and server. | ¶13(c) | col. 8:59-62 |
| (d) communicating the authorization message to the user computer... | The server communicates its signed certificate to the user's computer (the client). | ¶13(d) | col. 8:63-64 |
| (e) applying the public checking key to the authorization message for authenticating it... | The client uses the server's public key to encrypt a pre-master secret key sent to the server, which decrypts it; the client then compares results to verify authenticity. | ¶13(e) | col. 8:65-66 |
| (f) enabling said functional feature to run on the user computer if the authorization message is authenticated and if the integrity self-check result confirms that the computer program is in the anticipated state. | Allowing the website to run on the user's computer once the server's certificate is authenticated and the HMAC check confirms the program (the website interaction) is in an anticipated state. | ¶13(f) | col. 9:1-4 |
Identified Points of Contention
- Scope Questions: A primary question is whether the patent's claims, which are described in the context of "protected shareware" and monetization via a "billing agency," can be read to cover the general and ubiquitous protocol for establishing a secure (HTTPS/TLS) web connection. The infringement theory equates an SSL/TLS certificate with the patent's "authorization message" and basic web access with the enabling of "functional features." This raises the question of whether a standard security handshake for web access constitutes the specific software protection and authorization method claimed by the patent.
- Technical Questions: The complaint alleges that the HMAC process in TLS, which verifies the integrity of messages in transit, satisfies the "integrity self-check over the computer program" limitation. The patent, however, describes this check as a means "to ensure that shareware... is in an anticipated state," which is "equivalent to a finding that the code has not been altered." (’549 Patent, col. 2:50-54). This suggests a potential mismatch between checking the integrity of transmitted data (as in TLS) and checking the integrity of the program code itself (as described in the patent).
V. Key Claim Terms for Construction
The Term: "computer program"
- Context and Importance: The construction of this term is fundamental. The patent is titled “Protected Shareware” and consistently discusses protecting "executable computer programs." (’549 Patent, col. 1:9). The complaint asserts that the Defendant's website is the infringing "computer program." (Compl. ¶13). The viability of the infringement case may depend on whether a website, delivered as a set of resources to a browser, falls within the scope of this term as used in the patent.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification refers generally to "executable computer programs" and "software," terms that could arguably encompass modern websites that include executable client-side scripts. (’549 Patent, col. 1:9, 1:11).
- Evidence for a Narrower Interpretation: The patent's context is consistently focused on "shareware," a specific model for distributing installable applications. (’549 Patent, col. 1:51). The figures and detailed description depict a discrete "protected program 11" installed on a "user's computer 12" that interacts with external entities like a "billing agency 13," suggesting a standalone application rather than a transient set of web resources. (’549 Patent, FIG. 1; col. 3:17-23).
The Term: "integrity self-check over the computer program"
- Context and Importance: Practitioners may focus on this term because the plaintiff’s infringement theory equates it with the HMAC integrity check used in the TLS protocol for securing communications. (Compl. ¶13(c)). The defendant may argue that a check on message integrity is fundamentally different from a check on program integrity, as described in the patent.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim requires the check to confirm the program is in an "anticipated state." (’549 Patent, col. 8:61). Plaintiff may argue that an uncompromised communication channel is a necessary condition for the overall web application to be in an "anticipated state."
- Evidence for a Narrower Interpretation: The specification explicitly states the self-check is "to ensure that shareware, including its protective code, is in an anticipated state. Typically this is equivalent to a finding that the code has not been altered." (’549 Patent, col. 2:50-54). This language may support a narrower construction requiring a check on the program's code files (e.g., via a checksum), not the communication channel.
VI. Other Allegations
Willful Infringement
- The complaint alleges that Defendant has known of its infringement "since at least the date that Defendant was served with a copy of this Complaint." (Compl. ¶17). This allegation is limited to post-filing knowledge and does not plead any facts to support pre-suit willfulness.
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the term "computer program", as used in a patent describing a "shareware" protection scheme involving a "billing agency," be construed to cover a general-purpose public website, and can a standard SSL/TLS certificate be construed as the claimed "authorization message"?
- A key evidentiary question will be one of technical operation: does the TLS protocol's integrity check on in-transit data perform the same function as the claimed "integrity self-check over the computer program," which the patent specification describes as a check to confirm the program's code has not been altered?
- Finally, the prayer for relief requests a finding that the case is exceptional. (Compl. ¶D, p. 5). A central question for the court will be whether applying a patent for a specific software monetization method to the ubiquitous architecture of the secure internet is so tenuous as to meet the high bar for an exceptional case under 35 U.S.C. § 285.
