Patent citations as determinants of grant and opposition: case of European wind power industry

The grant of a patent and filing of an opposition are important events in the lifecycle of a patent. This paper tests the influence of backward citations on the likelihood of a patent grant and, if any, an opposition. Since all citations are not alike, detailed analysis is done by assessing type, nature and origin of citations in European search reports and, where needed, international search reports. The nature of citations, blocking or non-blocking, is found to have a significant impact on the likelihood of a patent being granted. The effect of citations originating during different stages of patent pendency is also explored in this study. For practitioners, the study provides a landscape of the European wind industry that is characterised by popularity of the PCT route, dearth of non-patent citations and dominance of bigger actors. For academics, the study offers novel opportunities to utilise citation based indicators.     

高校R&D与区域经济增长关系的实证研究

本文通过因子分析构造经济增长的复合指标,并利用2005—2006年我国31个省市高校R&D的相关数据进行回归分析和聚类分析。研究结果显示:高校R&D的专利授权对地区经济增长具有显著的促进作用,而研发的经费投入和人员投入对经济的推动作用不明显;高校的基础研究对地区经济发展至关重要;高校R&D的投入与产出不成正比,不同地区的高校R&D的经济效益差异较大,处于非均衡状态。因此,本文强调应在政策层面上重视基础研究,促进校企科研合作,提高研发经费的使用效率和研究人员的工作效率,加强区域协调,实现高校R&D与区域经济增长的和谐共进。     

A semantic analysis approach for identifying patent infringement based on a product–patent map

Identifying patent infringement beforehand is highly important for reducing the risk of damages. However, as the approach to patents is changing from the technological and legal approaches of the past to the business approach, strategic patent infringement litigation and securement of patents can be important tools for companies. From various viewpoints, companies can consider an aggressive patent infringement litigation as well as evasion strategy of patent infringement litigation to keep competitors in check. Previous research on patent infringement identification only considered the possibility of infringement between patents. However, infringement cases between patent and product are prevalent. Thus, this research aims to suggest an automated method for identifying patent infringement between the patent and product in business. To this end, this paper proposes the subject–action–object (SAO) semantic technological similarity-based product–patent method for generating infringement maps. Several indices and subgrouping methods are suggested to interpret the map. As an exemplary case, data on technology and products related to the light emitting diode (LED) lamp are collected and exploited.     

Technological innovation strategy: how do technology life cycles change by technological area

Discussions on the patterns of technological innovation have significant implications in terms of the efficient distribution of national R&D resources and the establishment of corporate managerial strategies. This study is focused on calculating and analysing technology cycle time (TCT) by technological area based on patent data that can be used as easily accessible objective indicators for the purpose of modelling the patterns of technological innovation by period and technological area. The main technological areas handled by the study include medical science, vehicles, metallurgy, and computing. Of the patent data registered with the United States Patent and Trademark Office from 1990 to 2014, International Patent Classification sub-class codes representing each technological area were selected to collect patent data, and to generate TCT statistics every five years. The TCT statistics generated is interpreted as the technological life cycle, to be used in modelling technological innovation patterns individualised by technology and period.

Impact of patenting on firms' performance: an empirical investigation based on manufacturing firms in India

The study aims to estimate the impact of R&D expenditure and patenting on the performance of firms using productivity, profitability and Tobin's q ratio as the performance indicators. The study uses firm-level data of 489 high- and medium-technology firms during the period of 2000–2010. We employ relatively a new source of data particularly in the context of India, firm-level patent granted, that has not been explored earlier. The study finds that firms patenting result in productivity improvement of firms, whereas R&D expenditure does not. The study further finds the evidence of positive impact of patenting on financial performance of firm with significant differences between foreign and domestic firms.     

Biases in patent examination and firms’ responses: Evidence from the pharmaceutical industry

Empirical analysis of matched patent application data in the world’s major patent offices has shown considerable variation in patent granting probability and examination duration across different countries. This phenomenon is attributed to institutional misclassifications or patent examiners’ mistakes by some authors. Others argued that cross-country heterogeneity could also be caused by deliberate manipulation of patent examination procedures with the goal to foster native inventors through suppressing foreign patent applicants. To explore whether manipulation exists, this study presents a case study of pharmaceutical patents granted by the US patent office and approved by the US FDA. Especially it focuses on the filing behavior of pharmaceutical companies in Korea, Japan and China. The regression results show that the granting ratio of the previous applications of a foreign company is correlated with the company’s probability of lodging a new patent application, which provides a supplementary evidence of the existence of the manipulated patent examination procedures.     

Cultural Enthusiasm,Resistance and the Societal Embedding of New Technologies: Psychotropic Drugs in the 20th Century

The societal embedding of new (medical) technologies involves not only market success, but also regulation and public acceptance. Cultural enthusiasm about their benefits and social concerns about their risks and dangers are in this respect important. Conceptualizing interactions between product championing, cultural enthusiasm and resistance, the article analyses three patterns of societal embedding: (1) hype-cycle, (2) contested embedding, and (3) controversy and stalemate. A fourth pattern of waves of enthusiasm and concern is proposed for technologies with unexpected side effects. This pattern is explored and elaborated with a longitudinal case study of the introduction of a particular form of medical technology: psychotropic drugs such as Veronal and Valium in the period 1900–2000.     

资本市场压力与企业策略性专利行为:卖空机制的视角

创新是一种不确定性高且周期长的投资活动,需要风险偏好更大、对失败容忍更高的市场环境,而资本市场具有筛选和发现创新型企业、有效分散创新风险的功能,因而对创新活动起着关键作用。然而,中国资本市场短期投资者比例高,融券交易成本高且交易不活跃,加上专利评价体系对不同质量的专利区分度较低,导致资本市场压力对创新活动没有发挥出信息机制和治理机制两种效应。相反,资本市场压力带来的负面信息表达渠道和管理层短期业绩压力,造成了中国专利申请中存在“重数量、轻质量”“重申请、轻维护”的企业策略性专利行为所衍生的“专利泡沫”问题。本文采用中国融资融券制度作为准自然实验,考察卖空机制对企业创新的影响效应和作用机理。研究发现,企业面临卖空压力时会更加积极地申请专利,但专利的申请质量有所下降,表现为专利授权率降低;专利结构有所恶化,最终授权数增加的主要是容易研发、授权快的实用新型专利和外观设计专利;专利得到授权后,企业放弃缴纳维持费用以终止专利权。这些策略性专利行为在短期内可以减少企业的卖空交易量,推高企业市值,但长期看对企业的业绩没有积极影响,是一种“创新假象”。卖空机制主要通过施压机制来影响企业创新,管理层业绩压力、外部监督压力、股价信息传递压力越大的企业,在面临卖空威慑时更有动力进行策略性专利行为。为促进企业创新向高质量发展,需要进一步完善融资融券制度和专利评价体系。     

被诉专利侵权企业之维权策略

当企业被诉侵犯专利权后应认真谨慎对待诉讼中的各项法律事宜并以积极的态度参与诉讼程序,为依法有效维护自己的正当权益,被诉企业及其代理律师应当掌握五项诉讼策略:于检索中应诉的策略;于答辩期内反诉原告专利权无效的策略;于被告提出经济担保时提供反担保的策略;于已认定为侵犯原告专利权时主动协商的策略;于法院确定为侵权后积极要求减少赔偿的策略。
