Purpose: This work presents a study on the female involvement in patent applications in all 23 Ibero-American countries that are WIPO members, in order to measure gender inequalities in institutional collaborations and technological fields, across time.Design/methodology/approach: The data used in this paper come from EPO Worldwide Patent Statistical Database(PATSTAT). PATSTAT contains bibliographical data relating to more than 100 million patent documents from leading industrialized and developing countries, as well as legal event data from more than 40 patent authorities contained in the EPO worldwide legal event data(INPADOC). The extracted subset is composed of 150,863 patent applications with priority years between 2007 and 2016.Findings: Our observations indicate that even in more dynamic economies such as Portugal and Spain, the participation of women per patent applications does not exceed 30%. Additionally, the distribution of female participation among institutional sectors and technological fields is consistent with previous studies in other regions and indicate a socio-cultural divide.Research limitations: Unisex names were not considered and were counted as gender unknown, and patent applications for which no inventor information was available were discarded, but further effort of data analysis may provide more information about gender inequalities.Practical implications: While patents are imperfect variables of inventive step and therefore should be considered as a variable proxy of innovation, our findings may help to guide the implementation of policies for balancing gender participation in innovative activities, as well as instigating research into the issues causing divisive participation along gender lines.Originality/value: While there is a widespread effort into evaluating and improving the participation of groups recognized as minorities within state-of-the-art activities, research about women participation in the innovation sector is fragmented due to differing regional characteristics: industrial and academic segmentation, socio-economic disparities, and cultural factors. Thus, localized studies present an opportunity of filling the gaps of knowledge on societal participation in innovation activities. 展开更多

The recent increase in patent granted in China prompts for an analysis of the various strategies which are certainly developed by Chinese applicants in that field. An analysis (APA Automatic Patent Analysis) has been done in several fields which have different impacts on the Chinese economy. We chose four different subjects: solar panels; photovoltaic panels; fireworks; and honeysuckle. These areas go from deep international concern to only Chinese interest. We analyzed in the different ratios between Chinese priority patents, Chinese patents extended to other countries, Patent extended from other countries to China and Chinese utility models. The results show clearly that various directions are followed depending on the economic importance of the field and also the pressure of the competition inside and outside China. In this context the strategic dependence (number of patents extended to China by other countries) was examined for each of the fields. We also show that in the domain where the man power is important such as fireworks the number of utility models is important. This suggests that utility models are used to spread in that field minor innovations. In the fields such as honeysuckle many applicants are the same that the inventors and the involvement of universities larger than in other fields. These two fields more or less centered on Chinese domestic aspects only a few patents (not for Honeysuckle) are extended to other countries. The impact of foreign patents in these two fields is quasi nil. In other domains such as photovoltaic panel the triadic patents (extension to US JP EP) are examined its show that if some Chinese patents are extended to other countries there are also an important numbers of foreign patents extended to China. This also suggests that in these most critical subjects, China develops a sort of technological protection barrier from domestic patents. This underlines a strategy on attack and defense in that field. 展开更多

Packaging is one of the most important methods of keeping the quality of food products for storage, transportation and end-use. The price of materials employed for packaging food has traditionally been high and used to be more expensive than the food itself. Technological innovations made possible to produce packaging materials cheaply. One of these processes is known as co-extrusion. This technique makes a film with two or more layers with different plastics not laminating the layers together with an adhesive, eliminating the use of solvents and producing a film in just one step instead multiple steps. In this background, our paper relates to the evolution on packaging for foods by using patenting documents. A search for patent documents was performed on free patent databases using keywords and International Patent Classification (IPC) codes related to this technology. As results: (a) 17% of the 21,472 documents found are focused on multilayer packaging for food; (b) 12 countries hold more than 90% of patents (38% Japan; 23% The United States of America; 7% Canada and 6% Germany); and, (c) two peaks were perceived in the period of 1992-1994 and 2003, and matches, respectively, the Persian Gulf (1990-1991) and Iraq Wars (2003-invasion of Iraq), so the historical tendency is confirmed: "wars also generate scientific and technological innovations". 展开更多

As the world transitions to a more environment-friendly and sustainable global economy,innovations in green technology are playing a crucial role.Recognizing this,China,along with many other nations,is adapting its pat⁃ent system to better support green innovations,establishing what is known as a green patent regime.While extensive empirical research highlights the significance of China's green patent regime in achieving environmental sustainabil⁃ity,there is a noticeable lack of normative studies on enhancing its efficacy.This work aims to fill this gap by conduct⁃ing a normative study using doctrinal analysis and proposing that transparency and accessibility are key factors in evaluating the effectiveness of a green patent regime.Through a doctrinal analysis of China's green patent legislation and regulations,this work assesses the legal rights conferred by this regime and identifies how these rights are con⁃strained by substantive and procedural norms.The findings reveal significant limitations to the transparency and acces⁃sibility of China's green patent regime and propose improvements.These recommendations offer insights for policymak⁃ers in China and other countries.The doctrinal analysis conducted in this research could stimulate further theoretical discussion in the field of sustainable development and intellectual property law.Moreover,it might enlighten more hy⁃potheses for future empirical studies. 展开更多

Embodied intelligence represents a new paradigm for the cross-integration development of artificial intelli⁃gence.By endowing AI with a"physical body",it enables interaction with the real world,allowing AI to move beyond digital environments into the physical realm and demonstrate intelligence that simulates or even surpasses human capa⁃bilities.Although embodied artificial intelligence demonstrates substantial potential in the realm of invention and cre⁃ation,there remain challenges in obtaining patent authorization for its generated technical solutions,specifically con⁃cerning subject,object,and market aspects.To address these issues,the feasibility of the subject should be demon⁃strated from the perspective of embodied cognition theory,while the object should be justified from a techno-centric standpoint.Subsequently,a regulatory framework for the patentability of technical solutions generated by embodied in⁃telligence should be proposed.First,a more inclusive subject framework should be established,recognizing embodied artificial intelligence as an inventor alongside humans,thereby affirming a coexistent"inventor"identity.Second,pat⁃ent rights should be assigned to developers of embodied artificial intelligence,referencing the rights distribution para⁃digm under employment relationships.Third,the criteria for patent eligibility and the"three-aspect"examination stan⁃dards should be refined.Finally,mechanisms for optimizing the implementation of rights and risk prevention should be developed. 展开更多

Rapid and accurate identification of high-quality patents can accelerate the transformation process of scientific and technological achievements, optimize the management of intellectual property rights and enhance the vitality of innovation. Aiming at the shortcomings of the traditional high-value patent assessment method, which is relatively simple and seldom considers the influence of patentees, this paper proposes a high-quality patent method HMFM (High-Value Patent Multi-Feature Fusion Method) that fuses multi-dimensional features. A weighted node importance assessment method in complex network called GLE (Glob-Local-struEntropy) based on improved structural entropy is designed to calculate the influence of the patentee to form the patentee’s features, and the patent text features are extracted by BERT-DPCNN deep learning model, which is supplemented to the basic patent indicator system. Finally a machine learning algorithm is used to assess the value of patents. Experiment results show that our method can identify high-value patents more effectively and accurately. 展开更多

The pitch bearing is a component in wind turbine units used to adjust the angle of the fan blades to adapt to the wind direction,so as to maximize the utilization of wind energy.Due to the different working mode of the pitch bearing itself compared with ordinary small bearings and the harsh working environment,the pitch bearing is prone to faults such as cracking and deformation.In severe cases,it will lead to overall damage to the pitch bearing,causing the blade to fall from a high altitude and even injuring personnel.Therefore,this paper conducts a patent analysis and technical decomposition of the deformation monitoring device for pitch bearings,analyzes and summarizes the development process of existing deformation monitoring devices for pitch bearings.Combined with the TRIZ evolution theory and based on the S-curve,it is concluded that the current deformation monitoring device for pitch bearings is in the transitional stage between the infant period and the growth period,and discusses the possible subsequent evolution directions.Through reviewing relevant literature,it is found that inner ring cracks first appear near the upper and lower surfaces of the bolt holes in the inner ring of the pitch bearing.To this end,a new type of deformation monitoring device for pitch bearings is designed.The fiber optic displacement sensor is used for qualitative monitoring of initial cracks near the surface of the bolt holes in the inner ring of the pitch bearing.After cracks are detected,the eddy current sensor is used for quantitative monitoring of whether there are extended cracks between the cracked bolt holes and adjacent bolt holes.Finally,the work done in this paper is summarized and prospected. 展开更多
