II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 6,212,662 - "Method and Devices for the Transmission of Data With Transmission Error Checking," issued April 3, 2001
The Invention Explained
- Problem Addressed: Standard error-checking methods in data transmission use a fixed function to generate check data (e.g., a parity bit). The patent asserts that "systematic errors," which repeat themselves, can consistently fool these fixed functions, leading to undetected data corruption (Compl., Ex. A, ’662 Patent, col. 1:47-59). This problem is particularly acute in compressed data streams, where a single undetected error can render all subsequent decoded data unusable (’662 Patent, col. 2:1-15).
- The Patented Solution: To overcome this, the invention proposes a variable error-checking function. Instead of applying a static check, the system first varies the original data in a time-dependent manner before generating the supplementary check data (’662 Patent, col. 2:30-47). This can be done, for example, by permuting the bits of the data or by combining the data with a pseudo-random number that changes over time, as illustrated in the patent's Figure 2 (’662 Patent, col. 4:24-45, Fig. 2). Because the check function effectively changes with time, the probability that a repeating, systematic error will go continually undetected becomes "minimal" (’662 Patent, col. 2:45-47).
- Technical Importance: This approach provides a more robust defense against certain types of persistent transmission errors, enhancing the reliability and integrity of data transfer, a critical requirement for telecommunication systems.
Key Claims at a Glance
- The complaint alleges infringement of "one or more claims" without specifying which, but its reference to a favorable PTAB decision on claims 3 and 4 suggests these may be a focus (Compl. ¶16, ¶21). The patent’s sole independent claim is Claim 1.
- Independent Claim 1 (Device Claim):
- A device for producing error checking based on original data provided in blocks with each block having plural bits in a particular ordered sequence, comprising:
- a generating device configured to generate check data; and
- a varying device configured to vary original data prior to supplying said original data to the generating device as varied data;
- wherein said varying device includes a permutating device configured to perform a permutation of bit position relative to said particular ordered sequence for at least some of the bits in each of said blocks without reordering any blocks of original data.
- The complaint does not explicitly reserve the right to assert dependent claims, but its broad allegation of infringing "one or more claims" implies such a reservation.
III. The Accused Instrumentality
Product Identification
The "Telit LE910 and related or similar communication devices, as well as technology or infrastructure making use of or incorporating the same or similar error checking technology" (the "‘662 Accused Products") (Compl. ¶21).
Functionality and Market Context
The Telit LE910 is part of a family of cellular communication modules designed for machine-to-machine (M2M) and Internet of Things (IoT) applications. The complaint alleges these products incorporate infringing "error checking technology" but does not describe the specific mechanisms by which this technology operates (Compl. ¶21). The complaint does not provide sufficient detail for a more specific analysis of the accused functionality.
IV. Analysis of Infringement Allegations
The complaint does not contain a claim chart or provide a detailed, element-by-element breakdown of its infringement theory. It asserts generally that the Accused Products infringe by "making use of or incorporating the same or similar error checking technology described in Ex. A [the ’662 Patent]" (Compl. ¶21). The following table maps the elements of Claim 1 to the complaint's high-level allegations.
’662 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| A device for producing error checking based on original data provided in blocks... | The complaint alleges that the Accused Products, including the Telit LE910, are communication devices that necessarily process data for error checking. | ¶21 | col. 7:2-5 |
| a generating device configured to generate check data; | The complaint alleges the Accused Products incorporate "error checking technology," which implies the presence of a device or function that generates check data. | ¶21 | col. 7:6-7 |
| a varying device configured to vary original data prior to supplying said original data to the generating device as varied data; | The complaint's allegation of infringement of the technology in the ’662 patent implies that the Accused Products contain a device that varies the original data before error checking. | ¶21 | col. 7:8-10 |
| wherein said varying device includes a permutating device configured to perform a permutation of bit position... without reordering any blocks of original data. | The complaint does not specifically allege the presence of a "permutating device." The infringement allegation rests on the general assertion that the Accused Products use technology "described in" the patent, which teaches permutation as a method of varying data. | ¶21 | col. 7:11-15 |
No probative visual evidence provided in complaint.
Identified Points of Contention
- Evidentiary Question: The primary point of contention will be factual and evidentiary. The complaint lacks specific factual allegations linking the claimed "permutating device" to the actual operation of the Telit LE910 module's error-checking protocols. The case may depend on what evidence Plaintiff can produce to show that the accused modules perform the specific function of "permutation of bit position" as claimed.
- Scope Questions: A central legal question will concern the scope of the claim term "permutating device." The dispute may focus on whether this term should be limited to the specific bit-swapping examples in the specification (e.g., ‘ABCD’ becomes ‘CADB’) or if it can be read more broadly to cover other forms of data manipulation used in modern communication standards that have a similar effect of varying the data over time.
V. Key Claim Terms for Construction
The Term: "varying device configured to vary original data"
- Context and Importance: This term is the central inventive concept. Its construction will determine the breadth of the claim. A broad construction could potentially read on various modern error-correction schemes, while a narrow one might limit the claim to the specific embodiments disclosed. Practitioners may focus on this term because the Defendants will likely argue that their standard-compliant error checking methods do not "vary original data" in the specific manner contemplated by the patent.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification describes the goal as making the checking function "time-dependent" and states that the "variable part is variable to the extent that another, in principle unknown, variation value... is continually conjoined with the data" (’662 Patent, col. 2:57-58; col. 4:14-17). This could support an interpretation covering any method that introduces a time-varying element.
- Evidence for a Narrower Interpretation: The specification’s primary examples of "varying" the data involve either adding a (pseudo)random number or performing a permutation (’662 Patent, Figs. 2, 3). A defendant could argue these specific disclosed embodiments should cabin the scope of the more general term "vary."
The Term: "permutating device configured to perform a permutation of bit position"
- Context and Importance: This term recites the specific structure of the "varying device" in Claim 1. The infringement analysis for this claim will hinge on whether the accused technology performs a "permutation of bit position."
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent does not define "permutation" in a restrictive way, leaving it open to its ordinary meaning of reordering elements. A plaintiff might argue any reordering of bits within a data block for error-checking purposes meets this limitation.
- Evidence for a Narrower Interpretation: The patent provides a concrete example: "A bit string represented by ABCD thus has the sequence CADB after one permutation" (’662 Patent, col. 5:63-65). A defendant may argue this example limits the scope of "permutation" to a direct, physical re-ordering of bit positions, as distinct from mathematical operations common in modern error-correction codes that might achieve a similar statistical result without an explicit bit-swapping step.
VI. Other Allegations
- Indirect Infringement: The complaint alleges inducement by asserting that Telit provides "instructions, product manuals, and/or technical information" that "direct or encourage" end-users and OEMs to use the Accused Products in an infringing manner (Compl. ¶22). Contributory infringement is alleged on the basis that the Accused Products are "especially designed or adapted to operate in a manner that infringes" and are not a "staple article of commerce suitable for substantial non-infringing use" (Compl. ¶23).
- Willful Infringement: Willfulness is alleged based on Telit's purported pre-suit knowledge of the ’662 patent, stemming from an invitation to take a license which it declined (Compl. ¶17, ¶24).
VII. Analyst’s Conclusion: Key Questions for the Case
This case appears to present several fundamental questions for the court's determination:
A threshold viability question: Arising from post-filing procedural history, the primary issue is whether any asserted dependent claims (e.g., claims 2-4) remain enforceable following the Plaintiff's disclaimer of the patent's sole independent claim, Claim 1, upon which they all depend.
A key evidentiary question: Assuming one or more claims are found to be enforceable, the case will turn on whether Plaintiff can produce sufficient technical evidence to prove that the Accused Products' error-checking systems perform the specific "permutation of bit position" as required by Claim 1, an allegation absent from the face of the complaint.
A central claim construction question: The outcome will likely depend on the definitional scope of the patent’s core terms. The court's construction of "varying device" and "permutating device" will be critical in determining whether the functions performed by the accused communication modules fall within the boundaries of the patent’s claims.
