Patents and Research Investments: Assessing the Empirical Evidence.
A well-developed theoretical literature - dating back at least to Nordhaus (1969) - has analyzed optimal patent policy design. We re-present the core trade-off of the Nordhaus model and highlight an empirical question which emerges from the Nordhaus framework as a key input into optimal patent policy design: namely, what is the elasticity of R&D investment with respect to the patent term? We th...
متن کاملPatents as Credence Goods
The view of patents as well defined property rights is as simplistic as it is ubiquitous. This paper argues that in newly arising or immature technologies, patents are subject to intrinsic and extrinsic uncertainty that make them very opaque representations of the underlying inventions. The opacity is a result of unsettled legal doctrine and scientific terminology, uncertain commercial and tech...
متن کاملPatents or Patents Pending
An Aluminum Nitride (AlN) MEMS resonator technology has been developed, enabling massively parallel filter and oscillator arrays on a single chip. Low loss filter banks and resonator arrays covering the 10MHz10GHz frequency range have been demonstrated, as has monolithic integration with inductors and CMOS circuitry. The high level of integration enables miniature multi-band, spectrally-aware a...
متن کاملPatents as a measure for eco-innovation
MEI is a project for DG Research of the European Commission (Call FP6-2005-SSP-5A, Area B, 1.6, Task 1) about measuring eco-innovation. The project is done in collaboration with Eurostat, the European Environment Agency (EEA) and the Joint Research Center (JRC) of the European Commission. MEI offers a conceptual clarification of eco-innovation (developing a typology) and discusses possible indi...
متن کاملPatents as Quality Signals for Entrepreneurial Ventures
To what extent do venture capital (VC) investors use information from patents to assess the quality of new ventures? Using a sample of 370 U.S. semiconductor start-ups, we examine when patents improve the terms by which new firms access venture capital.
