This article presents an innovative AI-driven framework for automated prior art search and patentability assessment through the analysis of semantic networks of technical literature. The system surpasses traditional keyword-based methods by integrating named entity recognition (NER), relation extraction, and knowledge graph construction to capture complex technical concepts and their interdependencies, enabling more accurate and comprehensive prior art identification.
The proposed architecture is designed for immediate deployment and is projected to reduce patent prosecution costs by around 30 percent and accelerate innovation cycles by enabling faster and more reliable patentability assessments. In the short term, it delivers efficiency improvements; in the medium term, it facilitates integration with patent office workflows; and in the long term, it enables the development of predictive models for patent invalidity.
Key components: NER acts as an intelligent selector of entities such as chemical compounds, device types, materials, and technical properties; relation extraction determines how these entities are connected in technical sentences and passages; knowledge graph construction converts entities and relations into nodes and edges that enable semantic searches and reasoning about indirect connections between documents.
Mathematical model and algorithms: the knowledge graph can be represented as G = (V, E) where V is the set of entities and E is the set of labeled relations. For prior art search, graph embedding techniques are used that project nodes into vectors in high-dimensional spaces and calculate similarity using cosine or other metrics. The impact prediction model is a regressor trained on patent history and graph features such as centrality, degree, and co-occurrence frequency that estimates rejection risk or the potential value of an invention.
Experimental methodology: a large corpus consisting of patent documents and scientific publications is used. Processing includes cleaning, tokenization, annotation for NER, and relation labeling as reference data. The set is divided into training and testing with classic evaluation metrics such as precision and recall to measure the ability to retrieve relevant prior art. Additionally, scalability is validated by measuring times and resource consumption across different corpus sizes.
Results and analysis: in comparative tests, the semantic approach shows significant increases in recall over keyword searches and improved precision by filtering false positives through contextualized relations. Illustrative example: a node Solar Panel connected by an edge improves to Efficiency allows detecting articles that address conceptual improvements to solar panels even if they do not use the exact terminology of the patent application.
Limitations and risks: the quality of the system depends largely on the quantity and quality of training data, there is a risk of biases derived from incomplete or amplified corpora, and processing can be computationally intensive during indexing and training phases. Performance in highly specialized domains requires adapted annotations and models.
Verification and reproducibility: the methodology includes annotated datasets as ground truth, generalization testing through cross-validation partitions, and NER and relation extraction benchmarks. The description of the core mathematical functions and evaluation metrics facilitates academic and industrial reproduction of the experiment.
Use cases and commercialization: the system is applicable to patent offices, industrial property firms, and corporate R&D teams that need rapid patentability assessments. A typical operational flow: application input, automatic extraction of entities and relations, graph construction, semantic query, and delivery of a report with prioritized documents and rejection risk scoring.
Technological outlook: integration with cloud services for scaling such as aws and azure cloud services, API deployment for integration with patent management systems, and development of AI agents that act as search and technology monitoring assistants. Artificial intelligence models and AI for businesses can be complemented with Power BI dashboards for graph visualization, citation analysis, and impact monitoring.
