A patent gives a patent holder (the “patentee”) the exclusive right to make, use, import, and sell his or her invention. The quid pro quo for obtaining a patent on an invention is disclosing in the patent how to make and use the invention. For this reason, a patent application must contain a detailed disclosure that teaches how to make and use the invention. Normally, this disclosure consists o...

-In this paper, we address the problem of patent valuation. With this aim in view, we focus on the feasibility and reliability of a patent rating system. This leads us to develop a structural model of patent renewal decisions based on real options that links patent renewals and patent value and to estimate it on micro level data. Results for a sample of European patents show that unobserved het...

This paper reports our experimental results at the NTCIR-6 English Patent Retrieval Subtask. Our previous participation at the patent retrieval Subtask revealed that the long length of the patent applications require less smoothing of the document model than general documents such as news paper articles. We setup the initial baseline retrieval system for U.S. patent applications and compare the...

Patent analysts predict trends in research and the business environment by studying the numbers and classifications of patents issued to companies around the world. Those attempts are often affected by the changes taking place in international treaties, governments, patent laws, patent classification systems, and corporate mergers and acquisitions. This paper describes some of the changes in th...

Google as one of the symbols of digital revolution has been influencing the world of searching from different aspects. Moreover, its place as a tool for information retrieval and research, and as a research topic for end-users and researchers is well known. As a result of Google’s pioneership in providing and changing, or to be precise, optimizing its services, it is being utilized by various i...

This paper investigates the effect of the threat and occurrence of patent litigation on the private value of patent protection. Potential challenges are introduced into a renewal model as a factor in patentee decisions as to whether a patent is worth maintaining. The model yields testable predictions about renewal probabilities. Data for post WWII German patents support the hypothesis that the ...

The standard rationale for patent claims is that they describe the invention and provide notice of patent infringement to competitors. This notice theory, however, is simply untrue—because patent litigation is highly unpredictable, claims do not provide notice of infringement. Accordingly, a large literature argues that claims are valueless, and that courts should instead determine patent scope...
