Leveraging AI to Streamline Patent Analysis: A Comprehensive Survey of Emerging Techniques

แนวคิดหลัก

Recent advancements in artificial intelligence (AI) and machine learning have enabled the development of transformative tools for streamlining various tasks in the patent life cycle, including classification, retrieval, quality analysis, and generation.

บทคัดย่อ

This survey provides a comprehensive overview of the recent research on AI-based methods for patent analysis. It covers over 40 papers from 26 venues published between 2017 and 2023.

The key highlights and insights are:

1. Patent Classification:

   • Traditional neural network approaches using LSTM, GRU, and ensemble models have been explored.
   • Adoption of large language models (LLMs) like BERT, XLNet, and RoBERTa has led to significant performance improvements.
   • Incorporating domain-specific pretraining (e.g., SciBERT) helps capture the technical language of patents.

2. Patent Retrieval:

   • Initial studies utilized traditional machine learning techniques like SVM, Naive Bayes, and decision trees.
   • Neural network-based methods, including CNNs and Bi-LSTMs, have been applied for both text and image-based retrieval.
   • Multimodal approaches combining LLMs (e.g., RoBERTa, Sentence-BERT) and vision transformers show promise.

3. Patent Quality Analysis:

   • Traditional neural networks, such as CNNs, Bi-LSTMs, and ANNs, have been used to predict various quality indicators.
   • LLMs, like MSABERT, can effectively process the multi-section structure and longer texts of patent documents.

4. Patent Generation:

   • Initial studies have explored using GPT-2 and BERT to generate patent claims and abstracts.
   • Challenges remain in assessing the quality and technical accuracy of the generated patent text.

The survey also discusses future research directions, including the need for multimodal patent datasets, leveraging generative AI for patent generation, and building comprehensive knowledge graphs for patent analysis.

สถิติ

Patents have a hierarchical classification scheme with 8 sections, 132 classes, 651 subclasses, 7590 groups, and 70788 subgroups.
The Cooperative Patent Classification (CPC) system is an expanded version of the International Patent Classification (IPC) and is collaboratively administered by the European Patent Office (EPO) and the USPTO.
Patent retrieval plays a crucial role in identifying new patents related to new inventions and ensuring that a patent does not infringe on existing patents.
Measures used for patent quality analysis include the number of forward or backward citations, the number of claims, the grant lag, patent family size, and the remaining lifetime of the patent.

คำพูด

"Recent advancements in Artificial Intelligence (AI) and machine learning have demonstrated transformative capabilities across diverse domains. This progress extends to the field of patent analysis and innovation, where AI-based tools present opportunities to streamline and enhance important tasks in the patent cycle such as classification, retrieval, and valuation prediction."
"AI-based tools can streamline the complex patent related tasks such as classification, retrieval, and valuation prediction. For instance, for patent examination, patent offices often rely only on the examiner to judge whether a technology is innovative and thus, patentable. However, it is challenging for the human examiner to stay updated on various domains due to the exponential growth in technology."

How can AI-powered patent analysis be further integrated into the patent application and review process to enhance efficiency and reduce human workload

AI-powered patent analysis can be further integrated into the patent application and review process to enhance efficiency and reduce human workload in several ways:

Automated Classification: AI algorithms can streamline the classification of patents by analyzing the text and images to assign appropriate classification codes. This reduces the manual effort required by patent examiners and ensures accurate categorization.

Enhanced Prior Art Search: AI can improve the prior art search process by quickly scanning through vast amounts of patent databases to identify relevant prior art. This accelerates the examination process and helps examiners make informed decisions.

Quality Assessment: AI models can assist in evaluating the quality of patents by analyzing various factors such as citations, claims, and patent family size. This automated assessment can provide valuable insights to patent examiners and applicants.

Generative Tools: AI-powered tools can aid in generating patent claims, abstracts, and other sections of the patent document. By automating the drafting process, these tools can save time and reduce the burden on patent writers.

Multimodal Analysis: Integrating AI models that can analyze both text and image data in patents can provide a more comprehensive understanding of the inventions. This holistic approach can lead to more accurate assessments and decisions.

By leveraging AI in these key areas of the patent application and review process, efficiency can be significantly improved, allowing patent offices to handle a larger volume of applications effectively while maintaining quality standards.

What are the potential ethical and legal considerations in using AI for patent generation and evaluation, and how can they be addressed

When using AI for patent generation and evaluation, there are several ethical and legal considerations that need to be addressed:

Bias and Fairness: AI models can inadvertently perpetuate biases present in the training data, leading to unfair outcomes. It is crucial to ensure that the AI systems used for patent generation and evaluation are free from bias and provide fair assessments.

Intellectual Property Rights: AI-generated patents raise questions about the ownership of the intellectual property. Clear guidelines and regulations must be established to determine the ownership of patents created by AI systems.

Transparency and Accountability: The decision-making process of AI models for patent evaluation should be transparent and explainable. Stakeholders should understand how AI arrives at its conclusions to ensure accountability.

Data Privacy: Protecting the confidentiality of sensitive patent information is essential. AI systems must adhere to data privacy regulations to prevent unauthorized access or misuse of patent data.

Regulatory Compliance: AI-generated patents must comply with existing patent laws and regulations. Legal frameworks need to be updated to address the unique challenges posed by AI-generated inventions.

Addressing these ethical and legal considerations requires collaboration between policymakers, legal experts, technologists, and stakeholders to develop guidelines and frameworks that ensure the responsible use of AI in patent generation and evaluation.

How can the insights from patent analysis be leveraged to drive innovation and technological progress in various industries

Insights from patent analysis can be leveraged to drive innovation and technological progress in various industries in the following ways:
