Patent Overview
- Title: "Method for Automated Widget Calibration Using Machine Learning"
- Assignee: TechCorp Inc. | Filed: 2019-03-14 | Granted: 2021-08-10
- Status: Active, maintenance fees current
Claim 1 (Independent) — Element Mapping
| Claim Element |
Your Product |
Match? |
| "A method for calibrating a widget comprising:" |
Your product calibrates widgets |
Yes |
| "receiving sensor data from a plurality of sensors" |
You use 4 temperature sensors |
Yes |
| "processing said sensor data using a trained ML model" |
You use a rule-based algorithm, not ML |
No |
| "adjusting calibration parameters based on model output" |
You adjust parameters automatically |
Partial |
| "iteratively repeating until convergence threshold met" |
Your system runs a fixed 3 iterations |
Partial |
Risk Assessment
| Claim |
Risk Level |
Rationale |
| Claim 1 |
Low-Medium |
Your rule-based approach likely does not meet the "trained ML model" limitation |
| Claim 2 (dep.) |
Low |
Adds "neural network" limitation — further distinguishes from your approach |
| Claim 3 (dep.) |
Medium |
Adds "sensor fusion" which your multi-sensor system may practice |
Key differentiator: Your use of rule-based algorithms instead of ML models is the strongest defense against Claim 1. However, if you plan to add ML capabilities, infringement risk increases significantly.
Recommendation: Low-medium overall risk. Recommend formal freedom-to-operate opinion from patent counsel before adding any ML features to the calibration system.
User: Find prior art that could invalidate Claim 1.

Potentially Invalidating References
Reference 1: US 9,876,543 (Smith et al., 2017)
- Title: "Adaptive Sensor Calibration System"
- Relevance: Discloses receiving data from multiple sensors and using iterative calibration
- Missing element: Uses statistical regression, not a "trained ML model"
- Strength: Medium — could support obviousness argument in combination
Reference 2: IEEE Paper, Chen & Patel (2018)
- Title: "Machine Learning Approaches to Industrial Sensor Calibration"
- Relevance: Describes using trained ML models for sensor calibration with convergence thresholds
- Missing element: Does not specify "plurality of sensors" — uses single-sensor examples
- Strength: High — teaches the ML calibration concept with convergence
Reference 3: EP 3,456,789 (Weber, 2016)
- Title: "Multi-Sensor Data Fusion for Equipment Calibration"
- Relevance: Multiple sensors, iterative adjustment, convergence criteria
- Missing element: Uses Kalman filters, not ML
- Strength: Medium — complements Reference 2
Combination Analysis
References 2 + 3 together arguably disclose all elements of Claim 1:
- Ref 2: ML model for calibration + convergence threshold
- Ref 3: Plurality of sensors + iterative parameter adjustment
Assessment: A reasonable obviousness argument (35 USC 103) could be constructed using References 2 and 3 in combination. Anticipation (35 USC 102) by any single reference is unlikely given the specific combination of elements.
Recommend patent counsel review these references for a formal invalidity opinion if needed for litigation or licensing negotiations.
