“…On the other hand, the number of patent applications in CN is the largest, indicating that CN might be one of the most potential markets of the ORC. (4) Most importantly, the technology life cycle of the ORC, based on the patent data, is at a growth stage, indicating that many products are developed and start being commercialized [17].…”

“…The technology life cycle can be divided into four stages [17]: introductory stage, growth stage, maturity stage, and decline stage. Figure 3 shows the evolution of number of patents vs. assignees, which is the typical figure to explore the technology life cycle base on the patent data.…”

“…Generally, during the growth stage the fundamental technical problems have been solved and the market uncertainty is vanished. Most importantly, many products are developed and start being commercialized [17]. Indeed, there are many commercial ORC products available now, such as products manufactured by General Electric Company and UTC Power Corporation.…”

This study presents a statistical analysis of patent data to explore the technological developments of the Organic Rankine Cycle (ORC). The ORC is considered as one of the most economic and efficient ways to convert low grade thermal energy to electricity. Patent data of this study are obtained from the commercial database, Thomson Innovation, which can be used to search the patent information from many countries and offices. With searching, screening, and patent family integrating by the International Patent Documentation Center (INPADOC), 304 patents are analyzed in the present study. The results show that the patent applications increase slowly before 2006, but increase significantly from 2009 to 2011 mainly due to the contributions from the applications in China and Republic of Korea. The year of 2009 can be regarded as a significant distinction year for the ORC development and patent application. The results also show that the assignee from United States is the most prominent. On the other hand, the number of patent applications in China is the largest, indicating that China might be one of the most potential markets of the ORC. The main International Patent Classification (IPC) of the patent data is F01K (i.e., Steam engine plants; Steam accumulators; Engine plants not otherwise provided for; Engines using special working fluids or cycles). Most importantly, the technology life cycle of the ORC, based on the patent data, is at a growth stage.

“…Novelty is defined in Section 102 of the US Patent Law: The invention is novel if it was not previously patented, described in a publication, in public use, or on sale by others before the inventor invented it. Trappey et al [35] use non-exhaustive overlap clustering to analyze patent documents with multiple technical descriptions of the invention. The results show that key phrases influence the similarity of the non-exhaustive clusters where an object is permitted to belong to no cluster.…”

With the growth of the knowledge-based economy, intellectual property right (IPR) is recognized as a key factor to develop and protect strategic competitiveness and innovation of an enterprise. The increasing degree of collaboration in global relationships, ubiquitous digital communication techniques as well as tough competition has lead to an increasing importance of intellectual property protection (IPP) for enterprises. Since the law as well as ethical principles are not always adhered to, there are increasingly activities outside legal understanding. This situation is exacerbated in the context of rising crime through the misuse of modern ICT technologies ("Cyber Crime") and now employs extensively state authorities. Piracy, counterfeits and unwanted know-how drain pose a significant problem for each market leader. Intellectual property is stored in product data too. Especially modern parametric and feature-based 3D-CAD systems have been enhanced towards acquiring, representing, processing and distributing knowledge to support knowledge-based engineering (KBE) within virtual product creation. However, it is very easy to exchange huge amounts of product data within a virtual enterprise that comprises an enterprise with its supplier network. There is an enormous threat that intellectual property could fall into the wrong hands and badly jeopardize the existence of the related company. This chapter contains an analysis of this conflict area, a picture of the legal framework, a discussion on the need for action in supply chain networks and attempts by research and development as well as best practices in industry for various aspects of IPP in the context of concurrent engineering (CE).
