Essays on the Empirical Analysis of Patent Systemsvan Zeebroeck, Nicolas 13 March 2008 (has links)
1. The context: The European patent system has been affected by substantial changes over the past three decades, which have raised vigorous debates at different levels. The main objective of the present dissertation is to contribute to these debates through an exploratory analysis of different changes in patenting practices – in particular the way applications are drafted and filed to patent offices –, their drivers, association with the value of patents, and potential impact on the patent system. The coming essays are therefore empirical in their essence, but are inspired by economic motivations and concerns. Their originality is threefold: it resides in the novelty of the main questions discussed, the comprehensive database specifically built to address them, and the range of statistical methods used for this purpose. The main argument throughout these pages is that patenting practices have significantly evolved in the past decades and that these developments have affected the patent system and could compromise its ability to fulfil its economic purpose. The economic objective of patents is to encourage innovation and its diffusion through the public disclosure of the inventions made. But their exploitation in the knowledge economy has assumed so many different forms that inventors have supposedly developed new patenting and filing strategies to deal with these market conditions or reap the maximum benefits from their patents. The present thesis aims at better understanding the dimensions, determinants, and some potential consequences of these developing practices.
2. The evolution: Chapter 2 presents a detailed descriptive analysis of the evolution in the size of patent applications filed to the European Patent Office (EPO). In this chapter, we propose two measures of patent voluminosity and identify the main patterns in their evolution. Based on a dataset with about 2 million documents filed at the EPO, the results show that the average voluminosity of patent applications – measured in terms of the number of pages and claims contained in each document – has doubled over the past 25 years. Nevertheless, this evolution varies widely across countries, technologies and filing procedures chosen by the applicant. This increasing voluminosity of filings has a strong impact on the workload of the EPO, which justifies the need for regulatory and policy actions.
3. The drivers: The evolution in patent voluminosity observed in chapter 2 calls for a multivariate analysis of its determinants. Chapter 3 therefore proposes and tests 4 different hypotheses that may contribute to explaining the observed inflation in size: the influence of national laws and practices and their diffusion to other countries with the progressive globalization of patenting procedures, the complexification of research activities and inventions, the emergence of new sectors with less established norms and vocabularies, and the construction of patent portfolios. The econometric results first reveal that the four hypotheses are significantly associated with longer documents and are therefore empirically supported. It appears however that the first hypothesis – the diffusion of national drafting practices through international patenting procedures – is the strongest contributor of all, resulting in a progressive harmonization of drafting styles toward American standards, which are longer by nature. The portfolio construction hypothesis seems a less important driver but nevertheless highlights substantial changes in patenting practices. These results raise two questions: Do these evolving patenting practices indicate more valuable patents? Do they induce any embarrassment for the patent system?
4. Measuring patent value: If the former of these two questions is to be addressed, measures are needed to identify higher value patents. Chapter 4 therefore proposes a review of the state of the art on patent value indicators and analyses several issues in their measurement and interpretation. Five classes of indicators proposed in the literature may be obtained directly from patent databases: the number of countries in which each patent is enforced, the number of years during which each patent has been renewed, the grant decision taken, the number of citations received from subsequent patents, and whether it has been opposed by a third party before the EPO. Because the former two measures are closely connected (the geographical scope of protection and length of maintenance can hardly be observed independently), they have been subjected to closer scrutiny in the first section of chapter 4, which shows that these two dimensions have experienced opposite evolutions. A composite measure – the Scope-Year Index – reveals that the overall trend is oriented downwards, which may suggest a substantial decline in the average value of patents. The second section of chapter 4 returns to the five initial classes of measures and underlines their main patterns. It appears that most of them witness the well-known properties of patent value: a severe skewness and large country and technology variations. A closer look at their relationships, however, reveals a high degree of orthogonality between them and opposite trends in their evolution, suggesting that they actually capture different dimensions of a patent’s value and therefore do not always pinpoint the same patents as being the most valuable. This result strongly discourages the reliance on one of the available indicators only and opens some avenue for the creation of one potential composite index of value based upon the five indicators to maximize the chances of capturing all potentially valuable patents in a large database. The proposed index reflects the intensity of the signal provided by all 5 constituting indicators on the potential value of each patent. Its declining trend reflects a rarefaction of this signal on average, leading to different plausible interpretations.
5. The links with patent value: Based upon the six indicators of value proposed in chapter 4 (the five classical ones plus the composite), the question of the association between filing strategies and the value of patents may be analysed. This question is empirically addressed in chapter 5, which focuses on all EPO patents filed between 1990 and 1995. The first section presents a comprehensive review of the existing evidence on the determinants of patent value. The numerous contributions in the field differ widely along three dimensions (the indicator of value chosen as dependent variable, the sampling methodology, and the set of variables tested as determinants), which have translated into many ambiguities across the literature. Section 2 proposes measures to identify different dimensions of filing strategies, which are essentially twofold: they relate to the routes followed by patent filings toward the EPO (PCT, accelerated processing), and to their form (excess claims, share of claims lost in examination), and construction (by assembly or disassembly, divisional). These measures are then included into an econometric model based upon the framework provided by the literature. The proposed model, which integrates the set of filing strategy variables along with some of the classical determinants, is regressed on the six available indicators separately over the full sample. In addition, the sensitivity of the available results to the indicator and the sampling methodology is assessed through 18 geographic and 14 industrial clustered regressions and about 30 regressions over random samples for each indicator. The estimates are then compared across countries, industries and indicators. These results first reveal that filing strategies are indicative of more valuable patents and provide the most stable determinants of all. And third, the results do confirm some classical determinants in their positive association with patent value, but highlight a high degree of sensitivity of most of them to the indicator or the sample chosen for the analysis, requiring much care in generalizing such empirical results.
6. The links with patent length: Chapter 6 focuses on one particular dimension of patent value: the length of patents. To do so, the censored nature of the dependent variable (the time elapsed between the filing of a patent application and its ultimate fall into the public domain) dictates the recourse to a survival time model as proposed by Cox (1972). The analysis is original in three main respects. First of all, despite the fact that renewal data have been exploited for about two decades to obtain estimates of patent value (Pakes and Schankerman, 1984), this chapter provides – to the best of our knowledge – the first comprehensive analysis of the determinants of patent length. Second, whereas most of the empirical literature in the field focuses on granted patents and investigates their maintenance, the analysis reported here includes all patent applications. This comprehensive approach is dictated by the provisional rights provided by pending applications to their holders and by the legal uncertainty these represent for competitors. And third, the model integrates a wide set of explanatory variables, starting with the filing strategy variables proposed in chapter 5. The main results are threefold: first, they clearly show that patent rights have significantly increased in length over the past decades despite a small apparent decline in the average grant rate, but largely due to the expansion of the examination process. Second, they indicate that most filing strategies induce considerable delays in the examination process, possibly to the benefit of the patentee, but most certainly to the expense of legal uncertainty on the markets. And third, they confirm that more valuable patents (more cited or covering a larger geographical scope) take more time to process, and live longer, whereas more complex applications are associated with longer decision lags, but also with lower grant and renewal rates.
7. Conclusions: The potential economic consequences and some policy implications of the findings from the dissertation are discussed in chapter 7. The evolution of patenting practices analysed in these works has some direct consequences for the stakeholders of the patent system. For the EPO, they generate a considerable increase in workload, resulting in growing backlogs and processing lags. For innovative firms, this phenomenon translates into an undesired increase in legal uncertainty, for it complicates the assessment of the limits to each party’s rights and hence of the freedom to operate on a market, which is precisely what the so-called ‘patent trolls’ and ‘submariners’ may be looking for. Although empirical evidence is lacking, some fear that this may result in underinvestment in research, development or commercialization activities (e.g. Hall and Harhoff, 2004). In addition, legal uncertainty is synonymous with an increased risk of litigation, which may hamper the development of SMEs and reduce the level of entrepreneurship. Finally, for society, we are left with a contrasted picture, which is hard to interpret. The European patent system wishes to maintain high quality standards to reduce business uncertainty around granted patents, but it is overloaded with the volume of applications filed, resulting in growing backglogs which translate into legal uncertainty surrounding pending applications. The filing strategies that contribute to this situation might reflect a legitimate need for more time and flexibility in filing more valuable patents, but they could also easily turn into real abuses of the system, allowing some patentees to obtain and artificially maintain provisional rights conferred by pending applications on inventions that might not meet the patentability requirements. Distinguishing between these two cases goes beyond the scope of the present dissertation, but should they be found abusive, they should be fought for they consume resources and generate uncertainty. And if legitimate, then they should be understood and the system adapted accordingly (e.g. by adjusting fees to discourage some strategies, raising the inventive step, fine-tuning the statutory term in certain technologies, providing more legal tools for patent examiners to reject unpatentable applications, etc.) so as to better serve the need of inventors for legal protection in a more efficient way, and to adapt the patent system to the challenges it is or will be facing.

Intellectual Property Management Strategy In New Technology-based Start-up CompaniesAktalay, Banu 01 December 2004 (has links) (PDF)
To draw up an intellectual property management strategy is one of the most important tasks to do when starting up technology-based companies, which play a very important role in the knowledge-based economies. IP management due to protection must be regarded as a strategic asset aimed at improving the competitive advantages, increasing the revenue of a technology-based start up company and encouraging to continue to develop new technologies, by securing a technological platform for a future development, preventing competitors from gaining access to emerging markets, creating retaliatory power against competitors and preventing innovative products from being plagiarized.
Through this study the aim is forming a guide including why and how an IP management strategy develop and implement to a new technology-based start up company. Beside these it is proved that from the properties that characterize the start-up configuration of a high-tech firm there can be derived three organizational archetypes of firms each of which requires different IP management strategies.

Valorisation économique de la propriété industrielle : cas de l'industrie pharmaceutique en tunisie / Economic valuation of industrial property : tunisian pharmaceutical caseBen gamra, Seima 14 January 2011 (has links)
La présente recherche vise à comprendre le processus ou le mécanisme de valorisation de la propriété industrielle aussi bien dans les pays développés que dans les pays en développement suite à la conclusion de l’accord historique ADPIC.L’analyse de données factuelles se rapportant à la protection de la propriété industrielle pharmaceutique en Tunisie nous oriente vers une modélisation possible de l’industrie pharmaceutique tunisienne.La recherche identifie deux voies ou stratégies d’exploitation des brevets : « license in » ou « license out ». Cependant, c’est le dépôt de brevet par les nationaux résidents qui fait défaut en Tunisie dans le domaine pharmaceutique, dominé par les biotechnologies à l’échelle mondiale.Le rapprochement des industries locales avec des partenaires scientifiques internationaux pourrait être une voie possible de valorisation. / We aim in this research to study how to assess the value of a patent in developed countries as well as in emerging ones, mainly according to the TRIPS.Modelization of the pharmaceutical industry in Tunisia has been possible when analyzing data evidence from pharmaceuticals patents in Tunisia.This research identify two strategies to capitalize on patents: « license in » ou « license out ».However, only few local industries in Tunisia are willing to file patents, even ifbiotechnologies dominate global pharmaceutical market.Being in touch with international scientific partners, signing contracts could help to valorize industrial property in Tunisia.

從國際趨勢看智財策略管理與企業經營整合-以企業內部智財策略與實施為例 / Enterprise Strategic IP Management:Integrating IP and Business Management within Organization陳奕之, Alex Yi-Chih Chen Unknown Date (has links)
從轟動全球的鴻海與夏普併購案、安謀與英特爾兩個直接競爭者間的晶片架構授權、蘋果與三星纏身多年仍難分難解的設計專利訴訟,再再都顯示智慧財產的重要性,及妥適的規劃與運用企業智財策略管理,能為企業帶來
的競爭優勢與經營彈性,可惜的是相關文獻不僅相當少,既有策略管理文獻,對智慧財產層面之策略管理,又鮮有論述。為期許自己能夠對實務及學術領域皆盡棉薄之力,並推廣相關知識,本研究選擇企業智財策略管理為研究標的,以有無積極採取此面向策略管理之利弊分析為主軸,分別涉及之具體考量為核心,再輔以國際案例說明,以應證智財管理與企業經營整合之趨勢。
為完整探討企業智財策略管理,本研究前兩章先思考廣泛認知的策略管理面向,並套用至智慧財產層面,說明智財策略管理為何及其重要性,與企業應將其導入日常經營;於第三章與第四章,倚賴客觀嚴謹之文獻解讀與專家訪談,搭配靈活之商業邏輯分析,試圖拉近古今中外類似策略思維,說明此概念實非前所未聞,毋寧係吾人未善加利用之競爭策略,並由具體事項整理欠缺企業智財策略管理之危機與積極採取企業智財策略管理之國際趨勢,以充分說明欠缺注意之問題與徹底落實之好處,本研究更利用柯達和全錄,說明企業是如何從默默無聞到高度成功,後續又為何日漸衰敗,並以波音與安謀,描述其係如何日益壯大,與善用智財策略管理更上一層,應證前述分析,係實質可期之策略應用;於第五章嘗試歸納、分析與整合相關資料,經過多次思考、討論與修正,提出企業宜進行之內部組織調整及12步驟之企業智財策略管理,給予企業一套有具體步驟的策略指引,嘗試協助企業成就更上一層,維持高度競爭力,並永續經營;透過深入探討企業智財策略管理議題,亦希冀能夠達到拋磚引玉之效,激發更多討論,補充本研究之不足。 / From recent Foxconn-Sharp merger, licensing deal among ARM and Intel, and dogfight be-tween Apple and Samsung; the importance of intellectual property (IP) is self-evident. Enterprises could gain competiveness and flexibility if strategic IP management is carefully planned and applied. Generous IP activities remained, but only a handful of scholarships dedicated to the topic; more likely than not, these papers focused on traditional perspectives, rather than strategic IP management. This research intends to provide an account broadly discuss relevant issues, including, what strategic IP management is, how it should be treated by enterprises, and guidelines of integrating it to business management. Hope the thoughts provided could benefit current practices as well as academics.
Chapter I & II described how the research is done, delved into traditional perspectives of strate-gic management, and construed strategic IP management to show the necessities of proper integra-tion for enterprises. Banked on resources and professional insights, Chapter III & IV carefully drew connections between strategic IP management and ancient Chinese wisdoms, and shown threats, benefits, and trends on why enterprise should incorporate strategic IP management into business. Further, it used famous corporations including Eastman Kodak, Xerox, Boeing Company, and ARM Holdings to show how successful businesses have failed due to careless on strategic IP management, in contrast to businesses indeed can benefited from proper integration of such instrument. Chapter V scrutinized materials, and integrated different opinions and perspectives, then provided adjustments to organizations within corporations and formulated a 12-steps strategic IP management intended to provide enterprises a guideline that would lead to further success. Lastly, Chapter VI provided a ret-rospect of the research, and wished to set an example and to stimulate more discussions.
