Welfare trade-offs between intellectual property (IP) protections provided by patents and by plant variety protection (PVP) are explored. PVP breeders’ exemption weakens IP protection, but may speed the transfer of research gains across firms. A model is developed assuming firms optimise research given existing IP protection. A baseline scenario supporting each system is used to perform welfare...

Patents are the main source of data on innovation. Since most of the innovative activity happens outside of the patenting system, and since patents −and innovationshave different quality, complexity, and impact on each market, unweighted sums of patents and proxies are an imperfect indicator of a country’s innovative activity. I generate two very simple indices of innovation (one dependent on t...

Patents in information and communication technologies (ICTs) are important instruments for protecting companies’ inventions to appropriate the value of related inventions. However, increasing dynamics complexity ICTs challenging effectiveness patents. Based on a review literature interviews with relevant stakeholders Europe, we have identified most challenges patents ICT possible solutions. The...

We participated in the patent mining task at NTCIR7 workshop. Particularly, our experiments focus on English corpus. Based on the Indri search engine, we implemented a patent classification system, which is able to assign a research paper into the IPC system according to the annotated patents in the database. As the task is a cross-genre classification task, we tried several methods to bridge t...

As the knowledge economy rapidly increases, intangible assets are more valuable to businesses and valuing them attracts much research from the field of technology management. Intangible assets include intellectual capital and intellectual property. Intellectual property is often protected by patents. Since the enterprise is willing to pay the patent costs to guarantee a sustainable competence, ...

Claiming intellectual property for an invention by patents is a common way to protect ideas and technological advancements. However, patents allow only the protection of new ideas. Assessing the novelty of filed patent applications is a very time-consuming, yet crucial manual task. Current patent retrieval systems do not make use of all available data and do not explain the similarity between p...

Many believe the root cause of the patent system's dysfunction is that the U.S. Patent & Trademark Office (PTO or Agency) is issuing too many invalid patents that unnecessarily drain consumer welfare. Concerns regarding the Agency's over-granting tendencies have recently spurred the Supreme Court to take a renewed interest in substantive patent law and have driven Congress to enact the first ma...
