Inside Oral Genome’s patented saliva-based diagnostics

What if a single drop of saliva could reveal more about your health than a trip to the doctor’s office?

Oral Genome is a startup focused on developing saliva-based diagnostics for early detection of oral health conditions. Its platform analyzes biomarkers in saliva to identify risks such as tooth decay, gum disease, and inflammation. The approach offers a non-invasive alternative to traditional diagnostics and is designed for use outside the clinic.

Connecting oral and systemic health through saliva-based testing

Oral Genome has developed an FDA-registered, saliva-based diagnostic that provides rapid, at-home insights into oral and systemic health. The system includes a test kit and mobile app. Users collect saliva, apply it to a test card, and capture an image with a smartphone. The app uses computer vision and machine learning to quantify biomarkers such as salivary pH, buffering capacity, Porphyromonas gingivalis, matrix Metalloproteinase-8 (MMP-8), nitric oxide, glucose, and salivary proteins. Results are available in about 15 minutes without laboratory processing.

Oral Genome: Patenting Activity

Oral Genome has been actively developing its intellectual property around saliva-based diagnostic devices, analytical methods, and companion mobile applications. The company currently has two active patent family applications that reflect its focus on digital oral health innovation.

EP4430633 protects the design of Oral Genome’s saliva test card and its image-analysis app for quantifying biomarkers such as pH, proteins, and enzymes. U.S. Pat. App. No. 2024/0248083 covers imaging systems that capture and analyze saliva test results for use in both clinical and home settings. 

Making oral health testing faster and smarter

Traditional health testing methods often rely on facility-based procedures that involve collecting blood or urine samples for laboratory analysis. This process requires professional handling, transport, and interpretation, leading to long waiting times and added costs. At-home testing kits offer more convenience but still depend on mailing samples to laboratories, which can delay results and risk sample degradation. These issues are especially limiting for oral health, where options for fast and accurate testing remain scarce. ELISA-based saliva assays, though effective, are costly, time-consuming, and prone to reduced accuracy as samples degrade within hours.

EP4430633 introduces a saliva-based testing method that simplifies and accelerates oral health diagnostics. The invention uses a portable device with colorimetric and lateral flow test areas that react to specific compounds in saliva. A smartphone captures an image of the reactions, and a digital testing platform interprets the results in real time. 

According to the patent, the system can identify enzymes, bacteria, and pH levels associated with oral health conditions, store results for trend tracking, and share data securely through a connected network. This combination of biochemical testing and digital analysis presents a practical, data-driven alternative to conventional laboratory-based approaches.

The patent application lists Tina Saw and Thanh Luu as inventors. J A Kemp is representing Oral Genome in the application. 

U.S. Pat. App. No. 2024/0248083A1 builds upon this concept by focusing on point-of-care efficiency and clinical applicability. It introduces a dental saliva test card integrated with a mobile app that uses computer vision to detect biomarkers linked to oral diseases such as caries, periodontal disease, halitosis, and Sjögren’s syndrome. 

Unlike general saliva testing platforms, this system emphasizes immediate, accurate results using fresh samples before degradation occurs. By eliminating mailing delays and reducing costs, it enables both clinics and individuals to perform rapid assessments. 

The patent application lists Tina Saw as the inventor. Legal representation was provided by Robert Freed, Michael Adams, Thomas Moga, and others from Dykema Gossett.  

Together, these patents define a unified testing system that integrates biochemical assays with digital imaging for personalized oral health insights.

Oral Genome: Top Technology Areas

Oral Genome’s top technology areas focus on diagnostic testing and healthcare informatics. The company’s innovations align with G01N-033, which covers methods for investigating or analyzing materials by determining their chemical or physical properties. More specifically, G01N-033/52 relates to biochemical assays and diagnostic devices that analyze biological samples such as saliva.

Oral Genome also operates within G16H, which focuses on healthcare informatics and information and communication technologies for medical data processing. Under G16H-010/40, the company’s work involves handling and analyzing patient-related data from laboratory or specimen testing, integrating these insights into digital health platforms.
