Secret sharing schemes perform an important role in protecting se-cret by sharing it among multiple participants. In 1979, (t; n) threshold secret sharing schemes were proposed by Shamir and Blakley independently. In a (t; n) threshold secret sharing scheme a secret can be shared among n partic-ipants such that t or more participants can reconstruct the secret, but it can not be reconstructed b...

IMPORTATION AS AN EXCLUSIVE RIGHT ¶1 Making, selling, or using a U.S.-patented product or process in a foreign country does not infringe the United States patent. United States law cannot govern in other countries, and the patentee’s remedy is therefore dependent on the laws of the relevant foreign country. But when the patented product (or the product of the patented process) is brought into t...

BACKGROUND Although it has been two decades since the Thai Patent Act was amended to comply with the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), there has been little emphasis given to assessing the implications of this amendment. The purpose of this review is to summarize the health and economic impact of patent protection, with a focus on the experience of Thai...

This paper considers the impact of the intellectual property (IP) system on the timing of cooperation/licensing by start-up technology entrepreneurs. If the market for technology licenses is efficient, the timing of licensing is independent of the patent grant date, and productive efficiency considerations will result in licensing as early as possible after invention. In contrast, the need for ...

Infective endarteritis (IE) was a fatal complication and the most common cause of death (45%) in patients with patent ductus arteriosus (PDA), before the introduction of antibiotic therapy and surgical closure of the ductus. The annual risk of IE in patients with PDA was estimated to be 0–45% [5]. Wide use of antibiotics and surgical closure of PDA has reduced significantly the incidence of IE ...

This paper examines the administrative practices of the patent offices in sixty countries over a 150-year period, a little-explored arena where government bodies and private firms interact. Larger and wealthier countries where international trade is more important give patent applicants more options. In these nations, patent office administrators’ flexibility is often restricted and the respons...

The economic implications of international patent harmonization have attracted little empirical scrutiny. Based on patent application and renewal data in major European countries since the early 1980s, this paper examines the empirical relationship between international patenting, R&D, and “trade flows” of patent rights across national borders. The analysis reveals a substantial patent “trade i...

Alice and Bob want to share a secret key and to communicate an independent message, both of which they desire to be kept secret from an eavesdropper Eve. We study this problem of secret communication and secret key generation when two resources are available – correlated sources at Alice, Bob, and Eve, and a noisy broadcast channel from Alice to Bob and Eve which is independent of the sources. ...
