摘要：

The average quality of agricultural biotechnology patents appears to have declined substantially during the past two decades. This quality deterioration may reflect either a decline in the significance of new inventions or an increased use of patents as "protective thickets" against competitors' challenges to more important discoveries. Either way, patent proliferation may be boosting the transaction costs in intellectual property markets, imperiling intellectual exchange and hence technical progress.
