"Cisco Vice President Mallun Yen said that the number of patent lawsuits against the company has quadrupled over the past five years. “The patent system overvalues patents, particularly weak ones, and thereby suppresses innovation,” she said. Yen disagreed with Peter N Detkin, founder and vice chairman of Intellectual Ventures, who attempted to recast the patent debate as one between big players, like Cisco and IBM, against individual inventors. Detkin said these small inventors do not want to commercial their inventions. Instead, they want to reap the appropriate reward and go back to inventing. As an example, Detkin cited an inventor who figured out a way to accelerate router speeds by 10 percent. That inventor didn’t want to compete against Cisco in the marketplace, but wanted to licence its technology to Cisco, he said."
