Prior-art retrieval is a crucial application of Patent Retrieval aimed to determine the novelty of a new invention. In this scenario patent authors require an exhaustive knowledge of all related patents and the search often involves multiple patent collections across the world, which do not share the same document structure or vocabulary. For this reason, despite of the numerous patent search a...

The aim of this paper is to provide new insights into (1) the determinants of the value of inventions and (2) the role that mobility plays in the behavior of prolific inventors, whom we identify based on the number of patents exceeding a threshold of productivity. We examine mobility in two dimensions: from firm to firm (inter-firm) and from one technical field to another. We exploit data on pa...

I examine the dynamic relationship between patenting, total factor productivity and openness to trade for a sample of twelve OECD countries from 1978 to 2004. Applying a technology-industry concordance to sort patents by sector, I study the sectoral shifts within countries throughout this period using a mathematical decomposition from international trade theory, constant market share analysis. ...

Adult IPRs are very important in trade competition, including patent rights. It can even be said that a is right considered the most valuable compared to other Patents will only granted an invention new, whether it of product, process or method, tool as mandated by Article 27 TRIPS Agreement. However, reality there patents have obtained Patent certificate though not new invention, namely ID No ...

A BASIC DESCRIPTION OF PATENT CITATION cycles is provided for 1,100 major companies and organizations covered by the TECH-LINEsM database. The average U.S. patent has five to six “references citedU.S. patent documents.” The properties of these patent citations are shown to vary widely from one technology to another. For example, patents in Office Computing and Accounting, a relatively hot area,...

Does the adaptation of incumbent firms to new methods of inventing follow similar patterns across industries and inventions? We investigate this question in the context of the revolutionary scientific advances enabling biotechnology and nanotechnology, both of which represent inventions of methods of inventing for incumbent firms. We hypothesize that an incumbent firm’s ability to exploit these...

We document that the Bay Area rose from 4% of all successful US patent applications in 1976 to 16% in 2008. This is partly driven by the increase in the prevalence of information and communication technology; however, even for patents unrelated to information and communication technology, we see a disproportionate increase in the share of all US patents from the Bay Area. We interpret this to s...

We examine whether prizes encourage innovation, and if so, how. We compare changes in U.S. patents per year for technology areas where U.S. inventors won prizes for exceptional innovations at the World’s Fair in London in 1851 with technology areas where U.S. inventors exhibited but did not win a prize. We also compare changes in technology areas for inventions that were advertised in 1851 as l...

Globalization, high growth rates in high-tech industries, growing emerging markets and harmonization of patent institutions across countries have stimulated patenting in foreign markets. We use a simple model of international patenting, where the decision to patent in a foreign country depends on country characteristics and the quality of the patented invention. With access to a detailed databa...
