As unmanned aerial vehicle (UAV), also called “drone”, swiftly advances with innovative functions and applications, the surge in patent applications has profoundly reshaped the intellectual property (IP) landscape in the UAV industry, leading to a growing number of litigations. This study is structured in two phases, aiming to develop an intelligent approach to analyzing the trend and evolution of patent litigations. The first phase involves macro- and micro-patent analyses of the related technology domain. Macro patent analysis elucidates the fundamental patent information in the drone industry, while micro patent analysis leverages the technology function matrix (TFM) to identify R&D hotspots and potentials. The second phase involves litigation (judgement) mining based on large language model (LLM). Beginning with the construction of a knowledge ontology, the domain infringement landscape can be detected through TFMs. A comparative analysis of the two-phase TFMs (i.e., both TFMs of patent and infringement allocations) is then conducted to pinpoint the key legal actions and the relevant technology. To drill deeper in infringement mining, dynamic topic modeling (DTM) is applied to analyze trends and dynamics in drone controller technology over time. This study aims to strengthen IP protection by developing an intelligent litigation mining approach that adopts large language model (LLM) and uses UAV/drone litigation studies as examples to show how the approach being applied in the industry.

Generative AI and Large Language Models (LLMs) are transforming patent law by automating complex tasks that traditionally demand significant legal and technical expertise. This paper examines AI-assisted systems designed to enhance patent drafting, prior art searches, and multimodal intellectual property (IP) protection. Human-in-the-Loop (HITL) frameworks play a crucial role in ensuring that AI-generated outputs remain accurate, legally compliant, and ethically sound, augmenting human expertise rather than replacing it.

We evaluate the applicability of LLMs such as GPT-4, Claude, and Gemini for patent-related tasks, highlighting their advantages and limitations. The study also explores critical challenges, including GDPR compliance, issues of interpretability, and the impact of outdated training data. Furthermore, strategies to mitigate AI-generated “hallucinations” and optimize prompt engineering for patent-specific applications are discussed. A comparative analysis of industry-leading platforms like Google Patents, PatSnap, and LexisNexis illustrates how AI tools are being integrated into patent workflows.

The paper provides both theoretical insights and practical recommendations for integrating AI into legal systems. By addressing the technical and ethical implications of AI-generated inventions, the study underscores the importance of transparency, accountability, and robust human oversight. This research aims to guide the seamless integration of AI technologies into patent law, promoting efficiency, accuracy, and compliance in an increasingly complex innovation landscape.

The pharmaceutical industry faces unique challenges in patent prosecution due to the broad scope of innovations that patents cover. Navigating the patent prosecution process is arduous due to various factors, including its inherent complexity and the potential for patentability rejections. The study developed a new dataset containing the Orange Book listed patents based on USFDA calendar year 2020 approvals. It aimed to analyze the patent prosecution process, specifically examining the severity of office action rejections through the patent rejection severity scale and their impact on prosecution timelines. Out of 437 patents, the claim scope significantly changed for 322 (65 primary and 257 secondary) during prosecution. The results indicated that the obviousness rejections occurred more frequently for secondary patents, with a rate of 72.76 % (187/257), compared to primary patents with 33.85 % (22/65). Further analysis revealed a strong association between the severity of office action rejections and the number of office actions (p-value of 0.0036) and prosecution time (p-value of 0.0008) for secondary patents. The study also emphasized the necessity of implementing various strategies and the use of experimental data to mitigate patentability rejections and circumvent prosecution delays. This information could provide practical insights to patent practitioners dealing with rejections.

Automatic patent claim generation is an emerging application of large language models (LLMs). However, the performances of general-purpose LLMs in this regard remain unclear. Here we empirically evaluate the effectiveness of four different LLMs (two from the LLaMA-2 family and two from the Mistral family) in generating biomedical patent claims. This allows comparisons between LLMs with different sizes and architectures. We show that these open-source LLMs fail to produce correctly styled patent claims despite their reported strengths in natural language tasks. Nevertheless, given selected training data and adequate fine-tuning, even relatively small LLMs can yield high-quality, correctly styled patent claims. Notably, one limitation of LLMs is that they lack the creativity and insights of human drafters. For such a professional task as claim drafting, LLMs should be considered as a digital assistant that requires human oversight.

The quality of patent application claims determines a patent's scope of protection and legal value. This study defines a new indicator based on claims structure to measure claim coverage, evaluate individual patents, and compare the strengths and weaknesses of competitors' patent portfolios in additive manufacturing technology. The new indicator's credibility is verified by comparing literature indicators.

Claim drafting is highly influenced by the official fees and legal regulations of national patent offices. Seven main additive manufacturing companies were selected to investigate their claim drafting strategies when applying for European patents while claiming priority in the United States. The indicators are shown on 2D maps of individual patents and patent portfolios. The ATT indicator is defined by independent claims representing attack strength, the DEF indicator is defined by dependent claims representing defense ability, and the TOT indicator is the sum of both. These indicators also represent the technical value of the patented invention, because more claims can be drafted for an invention with a wider range of technologies or more embodiments. 3D Systems and Stratasys make good use of domestic claim regulations to obtain higher patent values in the United States and Europe while minimizing fees.

专利申请权利要求的质量决定了专利的保护范围和法律价值。本研究定义了一个基于权利要求结构的新指标，用于衡量权利要求的覆盖范围、评估单个专利以及比较竞争对手在增材制造技术领域专利组合的优劣。权利要求的撰写受国家专利局官方收费和法律规定的影响很大。我们选取了七家主要的增材制造公司，调查它们在申请欧洲专利时的权利要求撰写策略，以及在美国申请优先权时的权利要求撰写策略。这些指标显示在单个专利和专利组合的二维地图上。ATT 指标由代表攻击强度的独立权利要求定义，DEF 指标由代表防御能力的从属权利要求定义，而 TOT 指标则是两者的总和。这些指标也代表了专利发明的技术价值，因为一项发明的技术范围更广或实施方式更多，就可以起草更多的权利要求。3D Systems 和 Stratasys 充分利用国内权利要求法规，在美国和欧洲获得了更高的专利价值，同时将费用降到最低。

Knowledge production activity is central within a technological innovation system. The number of patent applications is commonly used to evaluate this activity. However, it is subject to bias and inaccurate evaluations can occur. This article proposes a multi-criteria framework based on seven complementary patent indicators, taking into account the persistence, commitment, and coherence of knowledge production activities for a more comprehensive evaluation. We demonstrate the value of our proposal through a case study on hydrogen storage, comparing patent data since 2000 about three technological solutions: physical, chemical and adsorption technologies. Our framework clearly shows that physical hydrogen storage is the most advanced in terms of knowledge production, despite not having the highest number of patent applications.

This study delves into acne vulgaris, a chronic skin condition, marked by inflammation within the pilosebaceous unit. The significant economic burden of acne treatment is reflected in a burgeoning market poised for further expansion. Through patentometric analysis, aiming to identify technological trends, the research underscores the critical role of this method in identifying strategic opportunities within the anti-acne cosmetics and cosmeceuticals domain, pointing out China, the USA, South Korea, and Japan as pivotal in creating and consuming anti-acne technologies. The patent data reveals a pronounced focus on medicine and pharmacology, especially those derived from plant and animal sources. Patent applications have declined post-2017 suggesting shifts in research and development priorities and challenges in pioneering effective products. The applicants' temporal analysis and S-curve reflect the sector's maturity and growth trajectory. Despite the significant economic and societal burden of acne vulgaris, there is a lack of comprehensive studies that integrate patentometric insights with strategic market analysis, particularly focusing on the evolving trends in anti-acne technologies. This study includes the competitiveness indicators provided for the top companies worldwide. These indicators (e.g. patenting activity, technological share, average patent quality, patent strength, etc.) showed the strategic positioning of those actors. Ultimately, the paper proposes that the insights garnered could serve as a foundation for strategic allocation of financial and innovative efforts, underlining the need for advancements in treating acne vulgaris, a condition currently lacking a definitive cure.
