This study presents a comprehensive patent-based analysis of mRNA vaccine technologies, tracing their progression from experimental tools to scalable biomedical platforms after the COVID-19 pandemic. Leveraging Cooperative Patent Classification (CPC) codes and 25 years of global filings (2001–2025), we built a functional technology tree and mapped innovation across delivery systems, structural design, adjuvants and immune modulation, and Good Manufacturing Practice (GMP)-compliant manufacturing. Lipid nanoparticle-mediated delivery dominates recent applications, underscoring industry priorities in efficacy and scale. Growth curves signal entry into technological maturity, accompanied by wider participation from pharmaceutical firms, academia, and public institutes. Strategic profiling reveals contrasting R&D strategies: ModernaTX and Translate Bio pursue vertically integrated platforms; CureVac emphasizes antigen design and RNA stability; MIT focuses on delivery technologies with broad cross-domain reach. These patterns indicate that mRNA vaccines are becoming foundational infrastructure for precision medicine, oncology, and next-generation immunotherapies. Future competition is poised to intensify around delivery innovation, RNA stabilization, immune modulation, and robust GMP production. Our findings illuminate evolving intellectual-property strategies and highlight platform integration, manufacturing optimization, and cross-sector collaboration as key drivers of innovation in the global mRNA vaccine ecosystem.

The objective of this review is to discover systemic barriers and strategic possibilities that impact innovation, commercialization, and regulatory alignment by critically analyzing the patents of nanomedicine worldwide. The translational trajectory of nanomedicine is examined in relation to intellectual property (IP) frameworks, regulatory heterogeneity, and claim complexity.
Results
According to the report, the patent landscape is crowded and fragmented, with overlapping material and method claims delaying market entrance and driving up licensing costs by as much as 50 %. The intricacy of patent claims and disparate jurisdictional categorization schemes lead to protracted examination backlogs, which sometimes surpass 30 months. Timelines for patent drafting and clearance are complicated by regulatory misalignment, especially between the FDA, EMA, and other authorities. Early freedom-to-operate analyses, cross-licensing, and involvement in ISO/ASTM working groups are examples of strategic interventions that can reduce the number of transactions by 50 % and accelerate the time-to-market ratio by approximately 20 %. Reforms at the policy level, such as shared-IP incentives, specialist examiner tracks, and harmonized definitions (e.g., nanoparticle sizes of 1–100 nm), might reduce licensing costs by approximately 30 %. Patent landscape analysis in medicine and health care has transformed into a multidimensional, AI-powered endeavor integrating semantic extraction, graph theory, and economic modeling to reveal innovation hubs and strategic opportunities across diverse subfields. Clinical translation is facilitated, and public trust is increased when ethical, legal, and social factors are included throughout the R&D lifecycle. A robust and cohesive IP environment is necessary to realize the full potential of nanomedicine. This comprises an integrated regulatory-patent strategy, simplified patent office processes, enhanced examiner knowledge, and uniform definitions. In addition to increasing the quality and enforcement of patents, these reforms will increase competition, draw in investment, and hasten the introduction of nanomedicine advances to patients, which will ultimately lower healthcare costs and improve patient outcomes. To fully realize the therapeutic and financial promise of nanomedicine, this review discusses that standardizing patent definitions, expediting assessment procedures, and incorporating ethical frameworks are crucial. Innovation will be accelerated, prices will decrease, and patient access to cutting-edge treatments will be enhanced by a robust, internationally coordinated IP system.

Biodegradable metal implants are a significant innovation in medical science, offering temporary mechanical support and gradually dissolving within the body, thus avoiding the need for a second surgery. This study presents a comprehensive patent landscape analysis of metallic biodegradable implants: examining key trends, technological advancements, and major patent holders. Analysing 2114 global patent filings, the study identifies leading advancements in composition, manufacturing techniques, surface modifications, and clinical applications. There is clear information about the legal status of approximately 65 % of the total patent records, including granted patents that are still in force and those that have lapsed or discontinued due to non-renewal or other reasons. Specifically for India, a total of 177 individual patent application records involving filings in Indian jurisdiction resulted from a targeted screening procedure, with 99.4 % remaining active and 0.6 % marked as expired. However, biodegradable implant patent filings in India remain below expectations. This is attributed to the stringent application of Sections 3(i), 3(d), 3(f), and 3(e) of The Patent Act, 1970, that aim to minimize social costs in medical technology. These findings offer valuable insights for researchers, policymakers, and industry stakeholders navigating India's evolving patent landscape and future commercialization of metallic biodegradable implants.

Patent review is a time-consuming process because it involves the complexity of the documents with technical language and unpatterned files. Automating steps like data extraction can make technological prospects faster and more efficient. Thus, this study aimed to compare the use of an Artificial Intelligence (AI) tool to automate the data extraction of patents. A traditional patent review was conducted in Espacenet and WIPO databases, using the test subject: AI tools for skin cancer detection. Two independent reviewers performed the patent screening in Excel traditionally, and the data extraction step was manually made both and using SciSpace. SciSpace was 13.2 times faster than the traditional way and correctly extracted 69.7 % of information. Although it is a promising tool to accelerate the patent review process, it is crucial to author review the final version to ensure its accuracy and the representation of its ideas.

This study proposes a machine learning (ML) framework for predicting the value of renewable energy (RE) patents using a structured set of bibliometric and inventor-related indicators. Motivated by the strategic importance of clean technologies, a structured dataset of renewable energy patents is constructed using a technology-specific classification approach. In addition to widely used features, the study introduces and empirically tests three underexplored value indicators: first forward citation speed, lead inventor experience, and inventor team experience. Six ML algorithms; Naïve Bayes, Logistic Regression, Random Forest (RF), Extreme Gradient Boosting, Support Vector Machines, and Artificial Neural Networks (ANN), are implemented under five comparative strategy settings to evaluate classification performance. Results demonstrate that models trained with a comprehensive set of indicators significantly outperform those relying on limited features, with RF and ANN showing the strongest accuracy. SHapley Additive exPlanations are applied to interpret model behavior and quantify the influence of all indicators. While established citation-based measures retain importance, the newly introduced indicators provide consistent and meaningful contributions to model performance. The proposed framework advances patent valuation research by demonstrating how interpretable, data-driven methods can improve the prediction of valuable patents in policy-intensive technology sectors. These findings offer practical insights for technology managers, policy-makers, and innovation strategists seeking to enhance portfolio analysis, funding prioritization, and strategic decision-making in the context of green innovation.
