A common misconception exists among many scientists and engineers that a patent gives the owner the right to a particular technology. In fact, a patent does not guarantee the right to make or do anything. Instead, a patent gives the patent owner the right to exclude others from making, using, or selling anything that embodies the technology covered by the patent. When multiple organizations own...

In a model with endogenous number of innovating firms, we show that whether patent protection increases R&D investment is ambiguous, and depends on the market demand function and the cost of R&D. If the market size increases with number of firms, patent protection reduces R&D investment if the cost of R&D is sufficiently high, and higher product differentiation increases the possibility of lowe...

Patent document retrieval, as a recall-orientated search task, does not allow missing relevant patent documents due to the great commercial value of patents and significant costs of processing a patent application or patent infringement case. Thus, it is important to retrieve all possible relevant documents rather than only a small subset of patents from the top ranked results. However, patents...
