textttPatentAgent: Intelligent Agent for Automated Pharmaceutical Patent Analysis

Pharmaceutical patents play a vital role in biochemical industries, especially in drug discovery, providing researchers with unique early access to data, experimental results, and research insights. With the advancement of machine learning, patent analysis has evolved from manual labor to tasks assisted by automatic tools. However, there still lacks an unified agent that assists every aspect of patent analysis, from patent reading to core chemical identification. Leveraging the capabilities of Large Language Models (LLMs) to understand requests and follow instructions, we introduce the first intelligent agent in this domain, textttPatentAgent, poised to advance and potentially revolutionize the landscape of pharmaceutical research. textttPatentAgent comprises three key end-to-end modules -- textitPA-QA, textitPA-Img2Mol, and textitPA-CoreId -- that respectively perform (1) patent question-answering, (2) image-to-molecular-structure conversion, and (3) core chemical structure identification, addressing the essential needs of scientists and practitioners in pharmaceutical patent analysis. Each module of textttPatentAgent demonstrates significant effectiveness with the updated algorithm and the synergistic design of textttPatentAgent framework. textitPA-Img2Mol outperforms existing methods across CLEF, JPO, UOB, and USPTO patent benchmarks with an accuracy gain between 2.46% and 8.37% while textitPA-CoreId realizes accuracy improvement ranging from 7.15% to 7.62% on PatentNetML benchmark. Our code and dataset will be publicly available.
