Treatment of Oily Effluents Through the Combination of Flotation and Wetland in Thermal Plants Under the Focus of Patent Documents: A Prospective Study

This study aimed to present a technological search for technologies in the processing of oily effluents through the physical-chemical flotation and biological wetland process generated in thermoelectric plants in the patent database of the Derwent World Patents Index (DWPI) using keywords. We found few studies for thermal power plant-effluent processing technologies and combined technologies for flotation and wetland effluent treatment. Patents indicated high efficiency in the combination of the processes. We did not find studies in Brazil for treatment technologies of effluents in thermoelectric plants. However, due to the country's energy scenario, investments in research in this area are recommended.

Recent trends in the development of adsorption technologies for carbon dioxide capture: A brief literature and patent reviews (2014–2018)

Abstract According to a recent report published by the United Nations in 2018, the increase in global temperature is possible to hit the 1.5°C mark (the limit at which the detrimental impacts of climate change will be the most significant) between the year 2032 and 2050 due to the cumulative CO2 emissions within the atmosphere. Therefore, it is crucial to tackle global warming because of its serious repercussions such as extreme changes in global weather, which can significantly impact human health and ecosystem. Global warming is caused by the emissions of greenhouse gases; therefore, many countries have established laws and policies to lessen the emissions of greenhouse gases. This study highlights the recently published articles and patents on CO2 capture technologies through adsorption process from the year 2014 to 2018. Various types of adsorbent that can be potentially used to capture CO2 are discussed. The published patents were obtained from the Derwent World Patents Index and it was found that over 500 patents have been published on the diverse categories of adsorbents which can be used to capture CO2. The top five countries in the world with patents for CO2 capture technology via adsorption are China, United States, World Intellectual Property Organisation, Japan and Korea. This study not only provides a summary of the recent innovations in this area, but also shows relevant information and technologies, which will benefit a wide range of readers including academics, researchers and industry professionals. In addition, it also highlights the patents with current innovation technology, application of CO2 adsorption process in a real scale, patent applications filed in the past years in this field and knowledge gained from these patents which can be a guideline to develop various novel types of adsorbent and invent advanced technology in future.

Research and development on jabuticaba (Myrciaria Cauliflora): overview on academic research and patents

Abstract Myrciaria Cauliflora, popularly known as jabuticaba, is a Brazilian native fruit, rich in antioxidants, such as anthocyanins, flavonoids and tannins. In the wake of its properties, the jabuticaba is the study object of current paper which verifies worldwide research and technological development on the fruit. Data on academic research were retrieved from the following databases: Web of Science (WoS), Scopus and Scientific Electronic Library Online (SciELO) and the patents were retrieved from Instituto Nacional de Propriedade Industrial (INPI), European Patent Office (ESPACENET), Derwent World Patents Index (DWPI) and Patentoscope. Studies on the jabuticaba have been frequently developed in recent years and are concentrated in areas of agriculture and food science and technology. Further, there is a gap between scientific research and technological development, albeit complementary.

Knowledge flows from public science to industrial technologies

Scientific research has been acknowledged as an important knowledge resource for developing technologies. However, little is known about the heterogeneous nature of scientific knowledge and the associated contribution to technological advancement. Using nano technology as a case study, this paper investigates what types of scientific research can help improve the quality of technologies. This study uses backward and forward citation analysis, extracted from the Derwent World Patents Index. Non-patent citations from each patent are further connected with records indexed in Web of Science, and the forward citations for the cited articles are collected. On the one hand, our results confirm that there is an important contribution from science to technology. High-quality academic research has significantly contributed to the development of high-quality patents. On the other hand, this study also reveals the heterogeneous pattern of patents citing scientific publications, depending on the organizational type, country, and knowledge origin. Compared to those in the U.S., patents developed by Chinese inventors tend to reply on more recent science but with a narrower scientific scope.

Microbial bioremediation of oil contaminated seawater: A survey of patent deposits and the characterization of the top genera applied

Petroleum has been the world's major source of energy since the middle of the twentieth century, leading to positive changes but also social, political, and environmental problems worldwide. Oil contamination affects all ecosystems, and the remediation of polluted sites using environmentally friendly strategies is crucial. Here, we report an analysis of the patent documents of potential petroleum bioremediation techniques that use microbes to clean seawater. The patent search was performed using Orbit Intelligence®, SciFinder® and the Derwent World Patents Index®. A group of 500 patent documents were validated according to the search objective and carefully studied. Increases in patent deposits coincide with periods following widely reported oil spills, suggesting a relationship between media disclosure and stimulation of innovation activities. China leads the list of countries with patent applications in bioremediation with 152 deposits, followed by Russia with 133 and the US with 48. These three countries have completely different temporal deposit profiles, influenced by their historical, political, and economic scenarios. A total of 368 patents described degradation of the oil compounds exclusively by bacteria, 24 by fungi and yeasts, 1 by Archaea, 1 using a microalgal strain, and 32 by mixed consortia. The leading microbial genera found in the patents are Pseudomonas (114 patents), Bacillus (75), and Rhodococcus (60). In the top-10 list of microbial strains mostly cited/claimed, no genera are obligate hydrocarbonoclastic bacteria. This fact, together with the broad pattern found in the main International Patent Classification (IPC) codes, suggest that most of the documents are general bioremediation approaches and not focused on oil-polluted seawater. This work highlights the importance of stimulating the development of innovative environmentally friendly strategies focused on the degradation of oil hydrocarbons in marine ecosystems.

Patentes Farmacêuticas e Biofarmacêuticas: A Oportunidade Dos Países Farmaemergentes

Countries with emerging pharmaceutical market (pharmerging countries) has gained prominence in the international scenario because they are identified as the future responsible for the sustainable growth of the new medicines sale. In this work, a technological and industrial mapping was developed through the analysis of patent data extracted from the Derwent World Patent Index, as well as an association with R&D reports. Pharmerging countries were not represented by the industries that most invest in R&D, nor do they stand out in patent protection, poiting to low exploitation of their markets and inexpressive innovation indices. It is suggested that the pharmerging countries adopt public policies aimed at the innovation generation, especially in the biopharmaceutical segment that has proven to have much to be explored, in order to gain a competitive advantage

OPEN INNOVATION: SYSTEMATISATION OF KNOWLEDGE EXPLORATION AND EXPLOITATION FOR COMMERCIALISATION

This paper explores the intricacies of various determinants that can be used to systematise open innovation processes as the functional streaming of knowledge, both inbound and outbound, to expedite internal innovation and extricate the market for external use of innovation. Drawing on extant open innovation literature and data collected from organisations on the list of Thomas Reuters Derwent World Patents Index covering North America, Europe, Asia, Sub-Saharan Africa, the Middle East and North African for their open innovation practices, a model was developed that conceptualises the systematisation of open innovation processes toward commercial activities. The results show that the systematisation of open innovation requires a balancing act of knowledge exploration (KET) and exploitation (KEL) ambidexterity for commercialisation of the firm, and that a relationship exists between these variables. Using the contingency-based approach to organisational development, the paper adds to the understanding of the role of open innovation processes, systematisation, content and context as well as the research and development aspect of open innovation.

Patent analysis: a look at the innovative nature of plant-based cosmetics

The use of plants have become a important trend in cosmetic market, with a crescent number of patent applications. Despite various herbal-based ingredients have been described in scientific literature, most of them are restricted to patent databases. In this work we analyze the innovative use of plants and its derivatives in cosmetic technologies, based on patent analysis. The investigation was conducted using Derwent World Patents Index (Thomson Reuters Scientific, USA) from 1995 to 2015. The search was carried out to evaluate the number of patent deposits, the patent depositors profiles, the countries with most patent applications, the International Patent Classification (IPC) and the main plant families using in cosmetics. Patent analysis revealed an increase number of applications involving cosmetic containing plants components, with a higher number of deposits related to anti-ageing and whitening skin treatment. Fabaceae, Asteraceae, Rosaceae, Lamiaceae, Poaceae, Rutaceae, Lilliacae and Apiaceae were the key plant families used in cosmetic formulations for skin care treatment. Comparison between scientific and technological data pointed out divergences between patents deposits and aid-based scientific reports. The use of patent analysis in combination with scientific data opens up wider aspects of knowledge and enables a better rationalization of innovative works.

Using a distance measure to operationalise patent originality

ABSTRACTWe introduce a distance measure to operationalise Trajtenberg, Henderson, and Jaffe’s [1997. “University Versus Corporate Patents: A Window on the Basicness of Invention.” Economics of Innovation and New Technology 5: 19–50] originality construct (an ex-ante indicator of firms’ technological capabilities). Our measure captures (1) technological diversity, (2) technology distance from patent antecedents, and (3) degree of novelty per each patented innovation. The V-score measure uses the Derwent World Patent Index system to classify technologies hierarchically – making similarities and differences pronounced. Power is gained by using all of the technology-classification codes describing a focal patent’s claims when calculating whether its technology space was incrementally different or radical from those of its antecedent patents (and identifying whether its technology-class code combinations were commonplace at the time when the patent application was made). Our V-score’s prediction of firms’ performance is contrasted with Hall, Jaffe, and Trajtenberg’s [2001. Hall, B. H., A. B. Jaffe, and M. Trajtenberg. 2001. The NBER Patent Citations Data File: Lessons, Insights and Methodological Tools. NBER Working Paper No. 8498] Herfindahl measure of the same originality construct. Results indicate that the distance measure of technological content produces differently signed results when evaluating patents’ performance effects or predicting a firm’s trajectory.

Patent activity on water pollution and treatment in China—a scientometric perspective

This research intends to investigate the patent activity on water pollution and treatment in China (1985-2007), and then compares the results with patents data about Triadic patents, South Korea, Brazil and India over the same periods, patents data were collected from Derwent World Patents Index between 1985 and May 2008. For this study, 169,312 patents were chosen and examined. Total volume of patents, technology focus, assignee sector, priority date and the comparison with other countries are analyzed. It is found that patents on water pollution and treatment filed at China have experienced a remarkable increase and the increase rate of patents filed at China change simultaneous with the percentage of domestic applications. However, the number of high quality Triadic patents with priority country as China remains small. Furthermore, in addition to individual patent assignees, both Chinese universities and enterprises also play important roles in patent activity of water pollution and treatment. In addition, the pattern of South Korea's development can provide short-term implications for China and the regularity in Triadic patents' development can provide some guidance to China's long-term development. In contrast, the development pattern of Brazil and India is less influential to China's devel- opment. Furthermore, China's technology focuses on water pollution and treatment seem to parallel global and triadic patent trends. This research provides a comprehensive picture of China's innovation capability in the area of water pollution and treatment. It will help China's local governments to improve their regional S&T capability and will provide support the National Water Pollution Control and Treatment Project in China.

Comparing first level patent data with value-added patent information: A case study in the pharmaceutical field
