This article presents examples of the use of complex sheet metal in everyday life and the course of modeling a sheet bent simultaneously in two planes. The element selected to describe the modelling process is a fragment of the side wall of a lever hydroelectric power plant that operates on the Bystrzyca River in Lublin. The shape of the element is conditioned by the need to achieve a gentle change in the cross-section of the water stream during the flow between the steering system and the outflow area. The segment through which the water flows is clearly lower and wider than the other modules of the power plant, which is due to the average water level in the Bystrzyca River. Such a shape is necessary because the inflow and outflow parts of the power plant must be submerged under water all the time. This is due to the principle of operation of the power plant, which works by obtaining a vacuum created by pumping air from the inside. The article also presents the results of the strength analysis, which was performed for the segment exposed to the highest loads. The analysis and the entire design were performed in Autodesk Inventor, and the results obtained were as expected and even in the most critical places no values were reached that would require changes to the design.

This study uses patent citations data to measure knowledge spillovers at three levels: inventor, firm, and technology. We have collected Indian patents data granted by the United States Patent and Trademark Office (USPTO) and their backward citations from 1990 to 2019. To conduct our empirical analysis, we apply the Negative Binomial (NB) and Generalised Negative Binomial Model (GNBM). To account for other factors influencing knowledge spillovers, we control for patent inventor size, applicant size, patent scope, and claims. Our findings show that US-origin inventors outperform Indian and European inventors in terms of knowledge spillover from patent citations. Similarly, US firms show better knowledge spillover performance than Indian firms, foreign firms, Indian research centres, and other ownership categories. Lastly, the knowledge spillovers in chemistry technology patents are high compared to mechanical engineering, electrical engineering, and other technology categories from existing patent stock. The emperical finding of our study suggests that the government can promote knowledge spillovers from patent citations and advance India towards a knowledge-based economy by attracting foreign inventors and firms in the country, investing in domestic R&D, and developing human capital.

Bucket teeth are an important component of an excavator that functions as a material penetrator or digger. This part is prone to failure because it is in direct contact with the ground. This study aims to determine the value of stress, strain, deformation, and safety factors that occur in the Komatsu PC400 excavator bucket teeth against thickness variations of 2.5 mm, 5 mm, 7.5 mm, and 10 mm. This study uses a computer with specifications: processor: Intel (R) Celeron (R) N4000 CPU @ 1.10 GHz, memory: 8 GB. Windows 10 Home Single Language 64-bit Operating System. This computer is equipped with Autodesk Inventor Professional 2023 and ANSYS Workbench R1 2023 software. The method used in this research is a testing method using ANSYS software with a finite element method approach, namely static structural. The simulation results of bucket teeth show the maximum deformation values are 0.16382 mm, 0.13832 mm, 0.1249 mm, and 0.11619 mm, respectively. Furthermore, the maximum equivalent stress values are 108.6 Mpa, 79.712 Mpa, 80.338 Mpa, and 79.992 Mpa, respectively. For the equivalent elastic strain maximum, 0.00052993, 0.00038899, 0.000392, and 0.00039029 were obtained. Then the safety factor value is obtained 3.8214, 5.2062, 5.1657, and 5.188. This shows that the thicker the thickness variation, the better the strength value. [ABSTRACT FROM AUTHOR]

Increasing use of machine learning or “artificialintelligence” (AI) software systems in technical innovation has ledsome to speculate that perhaps machines might be consideredinventors under patent law. While U.S. patent doctrine decisivelyprecludes such a bizarre and counterproductive result, thespeculation leads to a more fruitful inquiry about the role ofcausation in the law of inventorship. U.S. law has almost entirelydisregarded causation in determining inventorship, with very fewexceptions, some of which are surprising. In this essay, I examinethose exceptions to inventive causality, the role they play indetermining inventorship, and their effect in excludingconsideration of mechanical inventors under current law.

This paper examines the impact of entrepreneurs' inventor identity and entrepreneur patent participation on enterprise performance using the panel data of 358 firms from the Science and Technology Innovation Board in China from 2014–2019. The methodology applied in this study is ordinary least square (OLS) regression. Inventor identity (a dummy variable) and patent participation (measured by Entrepreneur Degree Centrality and Entrepreneur Betweenness Centrality) are independent variables. The dependent variable enterprise performance is split into patent quantity, speed, and quality. The results show that an entrepreneur's inventor identity positively affects the patent quantity and quality but slows the patent speed. Entrepreneur Degree Centrality negatively affects the patent quantity and quality but increases the patent speed. Entrepreneur Betweenness Centrality positively affects the patent quantity and quality, and there is a U-shape association between Entrepreneur Betweenness Centrality and patent speed. The findings suggest that entrepreneurs who are inventors can actively improve the patent quantity and quality. Still, an entrepreneur's full participation in patent may negatively affect the patent quantity and quality. Entrepreneurs should participate in a patent in a direction-oriented or node-controlled way. [ABSTRACT FROM AUTHOR]

Latinas, along with many other minoritized groups, are underrepresented as inventors in the United States. Despite accounting for over 9% of the population, <1% of U.S. patent holders are Latina. In an effort to increase diversity among inventors and patent holders, a number of K-12 programs have been created to provide opportunities for students to participate in the iterative and recursive processes of inventing. One example is the emerging field of invention education. Invention education is an educational approach which teaches students how to identify and solve problems within their communities. Little is known about the experiences of Latina students who have participated in invention education and have begun developing identities as inventors. Through narrative methodology, we analyzed how the life experiences of one Latina student contributed to her identity development as an inventor. Four themes were developed through the analysis of the Latina student's narrative. The first was the early and consistent support of her family members. The second theme was the student's understanding of the importance of Latinx representation in STEM. The student's participation in extracurricular STEM activities was the third theme that contributed to the development of her identity as an inventor. The final theme was her continued involvement in engineering at the university level. While early, consistent, and continued identity work in extracurricular invention and STEM activities contributed to the development of an inventor's identity, literature has shown that opportunities such as these are not available to all students, especially those who have been historically underrepresented as inventors. We argue for making access to invention education more equitable by embedding it within the school day. [ABSTRACT FROM AUTHOR]

Artificial Intelligence, as one of the most important grounds of new technologies, infiltrates all aspects of human being life. one of these aspects is the inventions created by artificial intelligence, and this question will arise that if artificial intelligence would benefit legal rights of inventions? what is the necessity of recognition of this legal right, and what are the challenges of recognition in the framework of traditional system of intellectual property law? The current article studies the possibility of inventorship of artificial intelligence, with a focus on DABUS, the famous case in which DABUS is named as an inventor in a patent application. The current research tries to examine the possibility of reconciling the requirements of invention patentability with the specifications of artificial intelligence, and investigate the possibility of inventorship and ownership of artificial intelligence using an analytical-descriptive method while addressing the process of DABUS case. Although DABUS patent applications have thus far failed in most legal systems, most requirements of patentability coincide with the features of artificial intelligence. Even Civil law countries acknowledge that originality cannot be assessed according to artistic quality, and it is necessary to apply different standards of originality for different types of works. Thus, the basis of IP protection should be reviewed. This study concludes that the recognition of DABUS as an inventor in some international patent offices can be the beginning of making changes in new patent system and also the recognition of other legal rights, namely the personality right of artificial intelligence.

Abstract Based on the patent data from China National Intellectual Property Administration, we attempt to examine the effect of gender diversity in inventor teams on patent quality. We argue that gender diversity in inventor teams can promote patent quality, especially the invention patents that are high quality and radically innovative. Moreover, we find that the positive effect will be enhanced in places where women are well educated and improved by reducing gender discrimination. We propose that the effect will be more significant when market competition or market uncertainty is high as well as when the enterprises are private and growing. Ultimately, our study advocates that governments and enterprises should pay more attention to female labor forces, especially in the area of science and innovation, which is beneficial to improve innovation in China and eliminate gender inequality in the labor market.

Patent law remains stubbornly undertheorized; we have surprisingly little understanding of the social role of patents or its implications. To help address this deficit, this paper examines patents as performatives, that is, as social assemblages that enact what they disclose, and that create their own social facts. To demonstrate patent performativity, I briefly trace the development of performative concepts, from Austinian declarations, through Butlerian enactments, to Barnesian social constitutives. I then indicate how patents function in each of these respective modes of performativity, first as performative speech acts, then as normative inscriptions, and ultimately as mechanisms of social fabrication. Drawing on these observations, I identify what it means to perform patents, and suggest some practical and doctrinal implications of patent performativity, particularly for the “gender gap” that is manifest in the patent system.

Entrepreneurs and inventors as drivers of production and technology play an important role in the growth and development of any country. In our country, science and technology parks act as a support base for inventors, but so far no significant successes have been achieved in this field. The main goal of this research is to identify The obstacles to the success of inventors located in science and technology parks are in the science and technology park of West Azarbaijan province. The current research is an applied research in terms of purpose and a mixed research in terms of method. The data collection tools include interviews and questionnaires, and the statistical population of the research includes managers of growth and innovation centers affiliated to Science and Technology Park and managers of knowledge-based companies, who are called experts in this research. Purposive sampling method was used to select sample people. Maxqda and Excel software were used for data analysis. In this research, 13 in-depth interviews with experts were repeated. After completing the interviews and initial coding and extracting the articles for the final screening of the extracted codes, fuzzy Delphi was used. For this purpose, the questionnaire extracted from the interviews was given to the experts. Based on the fuzzy Delphi results, 69 themes in the form of 13 core codes were approved and agreed upon by the experts. The results show that financial issues, lack of information, lack of support Suitable products, product problems, market problems, licensing problems and management

Institutional and academic debates have intensified regarding the recent efforts to claim inventorship of AI-related patent applications, as has notably been seen in the known cases of Thaler v Comptroller ('DABUS') that have been examined in various jurisdictions. The pertinent question that has emerged is whether artificial intelligence systems can independently produce patentable subject matter. What has to be looked at, first, is the preliminary question of what the claim of producing inventions 'autonomously' can possibly mean under a technological perspective – an essential stage in the debate that is usually bypassed in legal commentary. Once such a technological explanation has been provided, a legal question can reasonably arise as to whether an AI process, such as software, may make a contribution that rewards a patent. AI inventions are legally approached and analysed as processes and as to their relationship with their direct products. Thus, where a process (AI) 'creates' or 'makes' a product, the focus is reasonably put on if and to what extent disclosing the product can provide a contribution separate to that which has already been provided by the process that created it. It is stressed that the current push for AI-generated products bypasses this key question which is essential in assessing the invention. [ABSTRACT FROM AUTHOR]

Legal scholarship has begun to consider the implications of algorithmic pattern recognition systems, colloquially dubbed “artificial intelligence” or “AI,” for intellectual property law. This emerging literature includes several analyses that breathlessly proclaim the imminent overthrow of intellectual property systems as we now know them. Indeed, some commentators have prophesied the demise of patentable innovation under the influence of AI research and development tools. Although AI systems pose fundamental challenges to the many areas of law and legal institutions, careful consideration suggests that intellectual property generally, and the patent system particularly, encompasses sufficient flexibilities to address AI innovation. In many cases, previous accommodation of biotechnology within the patent system points the way to similar accommodation of AI tools. However, the incorporation of AI innovation into patents reveals a significant gap in patent doctrine regarding causation, which deserves resolution quite apart from the furor over the intersection of AI and patent doctrine.

Inventions do not come in one format, so the right holder varies according to the occasion it reaches them. Only the financial rights are transferred to employers while the moral rights remain in the interest of inventors, as they are among rights closely related to personality and may not be waived with or without compensation. The worker's information, which is mainly associated with the establishment activity, becomes a weapon against employers if it falls into the hands of their competitors. Therefore, this research paper aimed to clarify what is meant by the worker and the employer, then define the invention types that the worker reaches during the implementation of the work contract. The study aims to distinguish labor law from other laws and then clarify the laws regulating the protection of workers’ inventions, their consequences, and what rules apply to it. The study also describes the legal effects that result before and after reaching the invention, as well as the rights and obligations of each party. This study followed the analytical approach of texts to get study results. Results showed that there are differences in the trademarks granted to foreign students, which necessitate attention in the applications granted to resident Jordanians and showed that there are differences for patents granted to foreign applications. Results also showed that Jordanian legislator came with a ruling that differs from what was stated in the Saudi law and the Omani patent law because the provisions of the Jordanian law talked about the case of accidental inventions and free inventions only. The study recommended adding some items to laws and legislations to be enforced in Jordan and deleting some texts and phrases that harm inventors. The study also recommends necessity to amend the text of article (22/b) of Jordanian labor law by deleting the phrase (unless otherwise agreed in writing) and replacing it with the phrase (and any agreement to the contrary is considered void).

In view of the complex structure, difficulty in design and miscellaneous information of the turbine, a design scheme of the Francis turbine based on BIM+ numerical simulation was proposed. Taking the HLFN-LJ-930 Francis flow turbine as an example, the application mechanism of BIM technology in the design stage was analyzed, and the way of BIM and numerical simulation data interaction was discussed. Then, with the help of fluid dynamics software Fluent, the RNG k-e model and SIMPLE algorithm were used to carry out CFD numerical simulation calculation and analysis of the turbine. The results show that the use of BIM collaborative work, information integration, visualization, collision detection and other functions can effectively solve various incongruity phenomena in the process of hydraulic turbine design, improve the design quality and efficiency. The information transmission of BIM and numerical simulation software is carried out by Inventor internal API interface, which improves the integrity of model data. The numerical simulation results show that the fluid flow inside the volute is good, there is local high pressure phenomenon at the head of the guide vane, and there is local negative pressure area at the back of the runner blade and the inlet of the tail pipe, which is prone to cavitation phenomenon. Further design is needed to improve its hydraulic performance. [ABSTRACT FROM AUTHOR]

We provide extensive surveys in eight estuaries along the coast of Ceará State in Northeastern Brazil, including local samples and data compiled from online data bases and literature. Samplings resulted in a checklist of the estuarine fish fauna, which recorded 126 fish species, and provides original information of some estuaries. Most of the sampled marine species are widely distributed and many are important commercial species for the artisanal fisheries. The addition of records from existing inventories and online collections increases the number of species to 245, of which 11 are threatened (critically endangered or vulnerable) and six are introduced. Our study provides an updated list of fish species of the estuaries along the semiarid coast of Brazil and is intended as a subsidy for further research, conservation and management efforts.

Protecting patent rights as principal example of industrial property rights and granting material and spiritual rights to the owner of the invention papers and the history of legislation of the issue in 1921, before ratification of such laws as Civil Code and Trade Law, indicate legal protection of patent rights. However, despite enactment of various domestic laws as well as many international conventions such as Paris Convention for Protection of Industrial Property (1883) and Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) with Islamic Republic of Iran joining some of these conventions, jurisprudential and legal foundations of this right in terms of lack of history of the issue in Islamic Law, as well as novelty of this branch of law – that is among the newly emerged issues according to some jurists – have created different challenges and viewpoints which are sometimes contradictory. This paper first reviews opinions for and against this branch of law, and while readdressing Imam Khomeini’s opinion concerning the subject, analyzes some legal foundations of the issue.

This research investigates the role of parents in explaining the surprisingly low presence of women among inventors despite their increase among graduates from science, technology, engineering and mathematics (STEM) subjects. With Danish registry data on the population born between 1966 and 1985 and an experimental setting crafted on siblings' gender composition, we find that the transmission of inventorship from parents to children disfavors daughters if they have a (second-born) brother. We complement this analysis with evidence about the role of parental factors at different stages of children's education. Overall, our results confirm that parental role models matter for children's education, especially at early stages and, through this, increase the probability of a child's becoming an inventor. However, the direct transmission of inventorship that favors boys much more than girls seems to be affected by gendered expectations developed by parents about daughters' and sons' returns from inventorship. Our study contributes to explaining who becomes an inventor and why by adding an important boundary condition to the literature: Parents are intermediaries who, based on their own interpretation of external information about inventive jobs, contribute to create or limit opportunities for their children.

Los avances en la tecnología de la inteligencia artificial han llevado a reconsiderar fundamentos esenciales del sistema de patentes. En particular, han confrontado los conceptos seminales de inventor, en la medida en que se cuestiona la posibilidad de que un sistema de inteligencia artificial pueda ser así categorizado. El propósito de este artículo es proponer un entendimiento sistémico e interdisciplinario de la actividad del intelecto artificial, con el fin de determinar si, con el desarrollo actual, se tienen nuevos inventores susceptibles de protección por la vía de la propiedad intelectual. Así, desde un paradigma positivista y utilizando técnicas cualitativas, esta investigación pretende contribuir, con un análisis jurídico, filosófico y técnico, a una de las discusiones más relevantes en la actualidad.

Does a person become more or less creative when exploring a new field? Exploring new fields exposes a person to new knowledge that might increase the novelty of inventive output; at the same time, exploration means a lack of prior expertise and a learning challenge that might harm the value of that output. Using new combinations as a measure of novelty and citations as a measure of value, we demonstrate correlations between exploring new fields and increased novelty-but decreased value-in an inventor-firm fixed effects panel. The negative effect of exploring new fields on value is muted when the novice collaborates with experts or uses the scientific literature in the new field. We find consistent results using an unintended change in noncompete labor law as an exogenous influence on exploring new fields. The research illustrates two opposite influences of exploration on creative output and suggests how inventors can reduce the downside of entering a new field.

While computer programs were purely tools for people to perform their creative activities 50 years ago, computer programs today, so called Artificial Intelligence(AI), can create intellectual products independently from people. The US has a leading role over all other countries in top-tier AI research, as well as most AI-related patent application filing. Does the US protect such inventions? If not, how does the US deal with liability concerning AI application? How does the development of AI call for intellectual property right law reforms in the US? The paper aims at addressing the above questions. Moreover, the paper provides a comprehensive analysis on AI-related patent in the US in comparison with the Vietnamese legal system. Descriptive legal research, analytical approach, comparison of legislation and case studies are employed in the paper. [ABSTRACT FROM AUTHOR]

There is still a lack of knowledge of Andalas University inventors on the importance of the Innovation Readiness Level (KATSINOV), which is a tool to measure the level of innovation. Therefore, it is necessary to hold socialization to the inventors and SMEs of Padang City to provide information about the importance of this KATSINOV. This socialization activity was carried out through a zoom meeting by inviting experts in this field. The method used is the presentation method, namely by providing socialization about KATSINOV to the inventors and tenants of Andalas University. In addition, the methods used were observation and direct interviews with Andalas University inventors to identify and measure KATSINOV's respective products. Socialization was provided by resource persons who understand KATSINOV. Katsinov is organized into six levels and seven key aspects covering technology, market, organization, partnership, risk, manufacturing and investment. This socialization activity resulted in the measurement of the level of product innovation readiness of Andalas University research. Furthermore, it was necessary to design a website-based application to facilitate the measurement of KATSINOV research products and West Sumatra MSME products.

Not only do advanced artificially intelligent (AI) systems play an increasingly important role in modern society, but they also significantly enhance industrial and economic development. AI systems are already capable of generating outputs, which, had they been created by humans, would be eligible for patent protection. Polish patent regime has yet to determine how it will address inventive computational results. This paper aims at addressing a question whether AI-generated outputs can be considered patentable inventions under Polish legal framework and if so, who would be recognized as the inventor. The author draws conclusions de lege lata and briefly outlines de lege ferenda observations. The author argues that vesting the inventor status in one of the persons who contributed to the AI-generated result offers a reasonable incentive to actors involved in the innovation process and, at the same time, leaving aside vexed problem of computational personhood, does not undermine established legal paradigms, in particular the traditional notion of human creator (inventor).

Artificial Intelligence and its subfield Machine Learning have considerable potential to improve the welfare of humans. Due to the specifics of Artificial Intelligence and its enhancing capabilities, there is an increasing incentive to innovate if the role of Artificial Intelligence in the inventive process is recognized not solely as a tool under the patent legal framework. Nonetheless, since the concept of an “inventor” is traditionally attributed to natural persons, there is no consensus on whether the mentioned term should be interpreted as a living instrument. This article focuses on interpreting the concept of an “inventor” under the patent legal framework. It outlines the potential approaches to address an incentive to innovate if the role of Artificial Intelligence in the inventive process not only as a tool is reflected. The main argument developed in the article is that proposals to amend the patent legal framework to address the issue might not be as preferred as introducing the certification system instead.

Edward Hartley Angle was an eminent American scientist, dentist, great inventor, being rightly considered to be the father of modern orthodontics. The great American scientist was the author of an impressive number of patents (46) and was the coordinator of 7 editions of some impressive orthodontic treatises. Thus, in this material, important data from the biography of Dr. Edward Hartley Angle.
