Construct a Three-Stage Analysis Model of Integrated Main Path Analysis and Patent Family-Exploring the Development of Blockchain
Proceedings of the 2019 3rd International Conference on Software and e-Business, 2019Co-Authors: Shu-jen Chen, Yu-hsin Chang, Kuei-kuei LaiAbstract:Regarding the evolution of technology, many scholars have used Patent citations, main path analysis and other methods to explore their development path ([1];[2]). These methods, however, are mostly external perspective of the company, which are the self-citing or mutual citation of the Patent literature in essence, focusing on analyzing the evolutionary path of the past and the present. This paper proposes a three-stage analysis model of Integrated Main Path analysis and Patent Family (IMPP secondly, integrating the main path analysis method is based on Patent citation, and find out the direction of dominant technical knowledge flow in the industry, as well as know well the assignees of the key Patented technologies; and then analyze the Patent families of the assignees, in order to gain insight into the strategic intent of their Patent portfolio and consider these Patents as potential candidates for standard essential Patents (SEP). This method takes the developing technology of blockchain as the research target. Through the mutual verification of the analysis of results and market information, it can be found that this method can explain the development of the technology-driven market. With the analysis method proposed in this paper, emerging technology investors can apply to predict the Patent portfolio intention and technology development direction of critical technology leaders, and then to decide how their companies' technical resources are invested when they with mature technology companies can think about how to make breadth of applications or even different industry alliances.

Note on a Heuristic Procedure to Identify the Most Valuable Chain of Patent Priority Network
International Journal of Innovation and Technology Management, 2015Co-Authors: Yu-hsin Chang, Kuei-kuei Lai, Wen-goang Yang, Ming-chung YangAbstract:A Patent portfolio is more valuable than a single Patent. However, the analysis approach of a company's Patent portfolio is still ambiguous. The Patent priority approach (PPA) presented a clearer analysis method to explore the interior of a Patent Family; Patent families provide an outline of the Patent portfolio. A Patent priority analysis (PPA) could give a better picture of the Patent portfolio path, and provide technical tracks through the Patent Family priorities. This paper evaluates the Patent Family priority network (PFPN), by joining whole Patent Family members to PPA. The length and quantity of the Patent chain represent the depth and width of the technical developments. Special nodes are also found. When the PFPN has any "merge Patents", the GR of the Patent chain would fail to choose the right critical chain. A burst Patent node bursts one path into several paths. SSR fails to choose the correct significant chain with burst Patent nodes. Although the number of priority Patents claimed by each Family member (GR) and the cumulative sum of the priority Patents for the Patent Family member (SSR) fail in the special situations, PFPN still could provide a simple, precise and broadly useful approach for technical development.

Note on a heuristic procedure to identify the most valuable chain of Patent priority network
2012 Proceedings of PICMET '12: Technology Management for Emerging Technologies, 2012Co-Authors: Yu-hsin Chang, Shao Yu PengAbstract:Patent portfolio is more valuable than single Patent. However, the analysis approach of a company's Patent portfolios is still ambiguous. Patent priority approach (PPA) presented a clearer analysis method to explore the inside of Patent Family. Patent Family provides an outline of Patent portfolio. Patent Priority Analysis (PPA) could get a better picture of Patent portfolio path and technical tracks through Patent Family priority. This article brings up Patent Family priority network (PFPN) by joining whole Patent Family members to PPA. Participating infringe law suit more than others do, the basic Patent shows important status of its Family. The length and quantity of Patent chain represent depth and width of technical developing. Special nodes are also found. When Patent Family priority network has any `merge Patent', GR of Patent chain would fail to choose the right critical chain. Burst Patent node bursts one path into several paths. SSR fails to choose the right significant chain with burst Patent nodes. Although GR and SSR fail in the special situation, PFPN still could provide a company a simple, precise and wide using approach of technical developing.

Valuable Patent or not? Depends on the combination of internal Patent Family and external citation
2010Co-Authors: Yu-hsin Chang, Wen-goang Yang, Kuei-kuei LaiAbstract:In this article, we are going to find out the Patent's real value of itself through Patent damage award. Damage award is what a Patent fight to win. It might be a good approach to get Patent monetary value. We find out a significant variable of forward citation representing deserved external reputation earned. Although Family size is not significant, it provides better protection as internal portfolio planed. A new joint random variable EPR earn plan ratio, forward citation counts divide by Family size, stand for whether a company internal strategical plan could earn external reputation. A low EPR represents that a company might put too much resource to less competitive innovations. It could help a company get its best Patent portfolio management.

Identifying the impact of Patent Family on the Patent trajectory: A case of thin film solar cells technological trajectories
Journal of Informetrics, 1Co-Authors: Kuei-kuei Lai, Priyanka C. Bhatt, Vimal Kumar, Hsueh-chen Chen, Yu-hsin ChangAbstract:Abstract Incessant technology development and evolution has thrusted the need to recognize promising technological opportunities for organizations. Since Patents contain information about an innovation, they are considered essential data sources for the development of new technology. The greater the size of international Patent families, the more valuable they are. This study analyzed the technological changes in a technology domain by eliminating the effects on evolution path caused by Patent families and discussed the implications of the technological path obtained from different parameters. This study builds on the assumption that the large number of Patent Family citations results in their increased influence, which affects the calculation of information flow in the path, and ultimately impacts the Patent trajectory. An iterative process was employed in this study to reduce the effect of Patent families, by establishing information flow, and map the main path network until the interference path from the main path was bifurcated. Technological innovation and the path phenomenon were identified through the key-route search attained using different paths. This study chose the case of thin-film solar technology and retrieved its Patent data from the United States Patent and Trademark Office (USPTO) database. The Main Path Analysis (MPA) and the technological trajectories’ analysis were utilized. The weight values calculated by the self-citation of the Patent Family create an interference path which are then adjusted in the global search, and a new main path is generated. Through this adjustment, the accuracy rate of identifying technological evolution and breakthrough innovation is enhanced.

Geocoding of worldwide Patent data
Scientific Data, 2019Co-Authors: Gaétan De Rassenfosse, Jan Kozak, Florian SeligerAbstract:Measurement(s) Patent • geographic location Technology Type(s) digital curation • geocoding Factor Type(s) geographic location • source • year Machine-accessible metadata file describing the reported data: https://doi.org/10.6084/m9.figshare.9970454 The dataset provides geographic coordinates for inventor and applicant locations in 18.8 million Patent documents spanning over more than 30 years. The geocoded data are further allocated to the corresponding countries, regions and cities. When the address information was missing in the original Patent document, we imputed it by using information from subsequent filings in the Patent Family. The resulting database can be used to study Patenting activity at a fine-grained geographic level without creating bias towards the traditional, established Patent offices.

The 'home advantage' effect and Patent families. A comparison of OECD triadic Patents, the USPTO and the EPO
Scientometrics, 2006Co-Authors: Paola CriscuoloAbstract:This paper examines the extent of the 'home advantage' effect in the USPTO and the EPO Patent data and in the OECD triadic Patent families. By comparing a set of internationalisation indicators for a sample of European, US and Japanese MNEs it finds that, contrary to what is often assumed, this effect is not only present in the USPTO but also in the EPO. OECD triadic Patent data, instead, are not biased towards any particular home country. It also finds that, because MNEs do not systematically file their Patents with the EPO, the USPTO and the JPO, the OECD triadic Patent Family dataset excludes many Patents, especially those invented in the US and accounted for in the USPTO, though it is mainly only low-value Patents that are excluded. Thus OECD triadic Patents can be considered a satisfactory alternative to the USPTO and the EPO for measuring R&D internationalisation.

Patent families: When do different definitions really matter?
Scientometrics, 2011Co-Authors: Catalina MartinezAbstract:Data on Patent families is used in economic and statistical studies for many purposes, including the analysis of Patenting strategies of applicants, the monitoring of the globalization of inventions and the comparison of the inventive performance and stock of technological knowledge of different countries. Most of these studies take Family data as given, as a sort of black box, without going into the details of their underlying methodologies and Patent linkages. However, different definitions of Patent families may lead to different results. One of the purposes of this paper is to compare the most commonly used definitions of Patent families and identify factors causing differences in Family outcomes. Another objective is to shed light into the internal structure of Patent families and see how it affects Patent Family outcomes based on different definitions. An automated characterization of the internal structures of all extended families with earliest priorities in the 1990s, as recorded in PATSTAT, found that Family counts are not affected by the choice of Patent Family definitions in 75% of families. However, different definitions may really matter for the 25% of families with complex structures and lead to different Family compositions, which might have an impact, for instance, on econometric studies using Family size as a proxy of Patent value.

Insight into Different Types of Patent Families
OECD Science Technology and Industry Working Papers, 2010Co-Authors: Catalina MartinezAbstract:What are Patent families? What is the impact of adopting one definition or another? Are some definitions of Patent families better suited than others for certain uses in statistical and economic analysis? The aim of this paper is to provide some answers to these questions, compare the methodologies and outcomes of the most commonly used Patent Family definitions and provide guidance on how to build families based on raw data from the EPO Worldwide Patent Statistics database (PATSTAT). One of our findings, based on a characterisation of Family structures, is that extended Patent families and other Family definitions, such as equivalents and single-priority families, provide identical outcomes for about 75% of the families with earliest priority dates in the 1990s because they have quite simple structures. Differences across definitions only become apparent for the families with more complex structures, which represent 25% of the families of that period. Eclairage sur differents types de familles de brevets Qu’est-ce qu’une famille de brevets ? Quelles consequences l’adoption de telle ou telle definition peut-elle avoir ? Certaines definitions des familles de brevets sont-elles mieux adaptees que d’autres a certains usages en analyse statistique et economique ? Le present document a pour objet d’apporter des reponses a ces questions, de comparer les methodologies et les resultats des definitions de familles de brevets les plus courantes et de donner des indications sur la marche a suivre pour construire des familles de brevets a partir des donnees brutes de la base de donnees mondiale de l’OEB sur les brevets (PATSTAT). L’une de nos conclusions, fondee sur une caracterisation des structures des familles de brevets, est que des familles de brevets etendues et d’autres types de familles de brevets, tels que les equivalents et les familles de brevets partageant la meme priorite, fournissent des resultats identiques pour 75 % environ des familles dont les premieres dates de priorite se situent dans les annees 90, car elles presentent des structures relativement simples. Les definitions ne commencent a diverger que pour les familles offrant des structures plus complexes, lesquelles representent 25 % de l’ensemble pour cette periode.

Patent analysis of technology-performance by integrating Patent Family and Patent citation
PICMET '09 - 2009 Portland International Conference on Management of Engineering & Technology, 2009Co-Authors: Kuei-kuei Lai, Kuang Ou Yang, Calvin S. Weng, Wen-goang YangAbstract:The value of mechanical engineering Patents often lies in innovative graphic designs and detailed complementary context. Therefore, without having the contents of a Patent thoroughly examined by experts, we cannot understand its true innovation value by using the current information analysis technology. Since, the process of qualitative research, on the other hand, is a complicated and time-consuming task, this paper proposes a Key Patent Analysis Process (KPAP). KPAP uses the ldquofocusing first, and then finding the detailsrdquo idea to prove the feasibility of this method by giving a specific case. Firstly, we propose using a Patent Family to effectively retrieve the key Patents to meet the requirements of the innovation design; then we propose proceeding to the next step using a Patent citation to broaden the search field to thoroughly comprehend the development in a specific technology field. Finally, we use TRIZ to create a technology performance map and technology development niche, and to effectively solve the possible engineering obstacles that may come to mind at the detail designing stage. The model suggested by this research can indeed promote the effectiveness of Patent technology to extract useful Patent intelligence; moreover, it improves the overall efficiency of new product designs.
