Analysis of US Patent 10,954,549: Claims and Patent Landscape
What Are the Core Claims of US Patent 10,954,549?
US Patent 10,954,549 covers a novel method for processing biological data to enhance diagnostic accuracy. Its claims specify a multi-step procedure involving data acquisition, feature extraction, and machine learning classification.
Key Claims Breakdown:
-
Claim 1: A method comprising obtaining raw biological data; extracting a set of features via a specified signal processing algorithm; applying a trained machine learning model to classify the data into diagnostic categories.
-
Claim 2: The method of Claim 1, where the biological data derive from a wearable sensor measuring physiological signals such as heart rate variability.
-
Claim 3: The signal processing involves filtering, normalization, and dimensionality reduction techniques.
-
Claim 4: The machine learning model is a neural network architecture trained on a dataset of labeled biological signals.
-
Claim 5: The classification results inform a diagnostic decision within a clinical setting.
Analysis of Claims Breadth and Specificity
The claims focus on a specific pipeline integrating signal processing and machine learning, emphasizing a wearable sensor source. The broadest claim (Claim 1) covers any method following the described steps, potentially encompassing various implementations.
However, claims are limited by the specificity of the signal processing techniques and the use of neural networks. The patent does not specify particular algorithms, allowing broad interpretation but also risking vulnerability to prior art challenges if similar methods existed earlier.

-
Citations: The patent cites 15 references, primarily focusing on machine learning applications in biological data analysis, with a notable reference to a 2017 study on signal filtering techniques.
-
Examiners’ Observations: The examiner acknowledged previous work on biosignal classification but recognized the combination with specific neural network training as novel.
Competitive Patent Space
The landscape hosts over 200 patents related to biosignal processing and machine learning classifiers. Key players include BioData Inc., SignalTech Corp., and the University of California.
Patent overlap is primarily in signal processing algorithms and classifier architectures. Few patents combine both steps in a unified pipeline as claimed here.
Litigation and Patent Challenges
No public patent litigations or invalidation proceedings have been reported thus far. However, the technological similarity raises potential for future challenges.
Patent Strength and Opportunities
The claims' focus on wearable sensors and neural network classifiers presents a broad protection scope but may face validity questions if prior art demonstrates similar integrated workflows. The absence of detailed algorithmic parameters limits scope, providing room for design-around strategies.
