Case Overview
The Parties
⚖️ Plaintiff
A patent assertion entity focused on QR code and symbology-related intellectual property. Its business model centers on licensing and litigation rather than product commercialization.
🛡️ Defendant
A global leader in continuous glucose monitoring (CGM) systems. Its G6 and G7 CGM platforms were the accused products in this case.
Patents at Issue
This case involved three U.S. patents asserted against DexCom’s commercially significant G6 and G7 continuous glucose monitoring applications. All three are directed to QR code and barcode symbology technology:
- • U.S. Patent No. 8,651,369 — Methods and systems for encoding, displaying, and processing two-dimensional barcodes.
- • U.S. Patent No. 8,424,752 — Methods and systems for encoding, displaying, and processing two-dimensional barcodes.
- • U.S. Patent No. 8,936,190 — Methods and systems for encoding, displaying, and processing two-dimensional barcodes.

The Verdict & Legal Analysis
Outcome
Chief Judge Gilstrap granted DexCom’s motion in full. Symbology’s First Amended Complaint was dismissed with prejudice, meaning Symbology cannot re-file the same claims against DexCom on these patents. DexCom was designated the prevailing party and awarded its costs. No damages were assessed against DexCom, and no injunctive relief was granted to Symbology, representing a categorical defense victory.
Key Legal Issues
While the detailed legal reasoning is not fully specified, the dismissal of a first amended complaint with prejudice commonly arises from:
- • Failure to State a Claim (Rule 12(b)(6)): Inadequate pleading specificity, failing to map accused product functionality to each patent claim element.
- • 35 U.S.C. § 101 Patent Eligibility: The asserted claims were likely found directed to abstract ideas (e.g., encoding or decoding information) without a sufficiently inventive concept, under the Alice Corp. v. CLS Bank International framework.
- • Claim Mapping Deficiencies: DexCom’s defense likely demonstrated that its G6 and G7 applications do not practice one or more essential limitations of the asserted claims, rendering the complaint legally deficient.
This outcome contributes to an emerging body of Eastern District of Texas rulings disciplining insufficient patent assertion pleadings, even in a plaintiff-favorable venue.

Three U.S. patents were asserted: U.S. Patent Nos. 8,651,369; 8,424,752; and 8,936,190 — all directed to QR code and barcode symbology technology.
DexCom’s motion (Dkt. No. 25) was granted in full, resulting in dismissal with prejudice of Symbology’s First Amended Complaint. Specific legal grounds are consistent with pleading sufficiency or § 101 eligibility challenges, though complete motion details require PACER review.
The dismissal reinforces that QR code and symbology patent claims against mobile health applications face significant early-stage legal risk, particularly when asserted by patent assertion entities against defendants with sophisticated IP defense resources.
Companies can protect themselves by conducting Freedom-to-Operate (FTO) analysis before implementing QR code and symbology features, documenting technical distinctions in their implementations, and proactively addressing potential § 101 eligibility issues.
