INTRODUCTION RINTED electronics has emerged as a potential technology for many cost effective and large area applications as in tags, displays, sensors, OLED’s and photovoltaic’s. This technology is currently experiencing a growing interest and garnering attention in both academic and industrial aspects of Research and Development. Digital Devices produced by Printed Electronics provide two principle advantages over Conventional Electronics, firstly they can be fabricated at Low Temperature and allow simple integrated circuits to be fabricated at extremely low cost for various large area applications such as radio-frequency identification tags, In a similar fashion like printing on paper they can be used to “print” disposable Electronics Circuits. 1 Manipal Technologies Limited, Manipal, India 2 Industrial and Management Engineering, Indian Institute of Technology Kanpur, India 3 National Centre for Flexible Electronics, Indian Institute of Technology Kanpur, India * Corresponding author’s e-mail: [email protected]Similar to the bunch of potential Printed Electronics products, Passive Printed Tags have applications in diverse areas like asset management, monitoring, identifying and tracking of people especially in work environments such as military bases, power plants, airports, hospitals, refineries and access restricted areas is emerging. The necessity for human moment monitoring by tagging is emerging, where the tag will be external to the body. This kind of application requires bulky wrist bands or ID badges, which can be printed [1]. During day to day operations Tags are expected to lead to Improvements in automation, inventory control, and checkout/purchasing operations [2]. Thereby Printed electronics holds promise for realizing ultra low cost Printed Tags. Based on the importance of printed electronics and Printed Tags there has been incremental growth in Research and Development in this sector. However, research so far has paid very little attention to determine the nature of evolution of this technology and the trends emerging [3]. A patent is used as a proxy for technology or knowledge itself [6]. Broadly patents are accepted as a quantitative measure of the performance of investment in research and development (R&D) [4]. Using patent data there have been lots of studies on the performance of technological innovation. For the inception of any such studies there is requirement to determine the Number of patents being filed for the entire technology [5]. Further investments in an Innovative Technology are done on the basis of the stage in which a particular technology is in the technology life cycle (TLC). Patent data can be used to predict the success and the present state of technology [6]. During formulating strategy for technical collaborations and investments, it is critical to know the countries and current assignees which are holding the highest number of patents in the field of interest. We will showcase these aspects for Printed Electronics Technology. II. PATENT DATABASES Patent provide the legal rights to Inventor within the geographical area in which a patent is filed. Therefore a Inventor will file a patent in the countries in which Inventor determines his Intellectual knowledge will be useful and can have commercial viability. All the patents for a are not filed in one particular patent database. To understand the Technological Evolution it is important to consider various patent databases. For the purpose of Patent retrieval and analysis we have used lexis nexis total patent database (https://www.lexisnexis.com/totalpatent/signonForm.do).

Abstract— Printed electronics (PE) refers to the application of
various printing techniques for the fabrication of electronic circuits
and devices. This emerging discipline promises to revolutionize the
field of electronics and provides an extension to conventional
electronics by enabling the mass production of low cost, flexible
digital devices in a wide array of substrates, such as textiles, paper,
or plastic. Printed Tags are the best examples of this technology
which can provides a promising potential pathway toward the
realization of ultra low-cost Intelligent tags which can be used for
the purposes such as item-level tracking. For the past two decades
there has been considerable research and development activity and
business interests in this promising technology. As for any
technology, knowledge created is in the form of Publications and
Patents. A technology life cycle (TLC) for a specific technology
based on Patent data helps to determine the present state of
technology in its life cycle, which will act as the basis on which
decisions regarding how to proceed with further business
investments and technological advancement can be made. In this
work in order to retrieve the patent registration data in various
patent databases, we build a query system on the basis of which we
determine and trace yearly patent registration record in the field of
Printed Electronics. This information will be useful to understand
the present state of the Technologies under consideration.
