liz: john allison, cato institute.t bankers in history. >>> no question number of lawsuits over patent infringement has been skyrocketing. last year 6,000 claims entered u.s. courts. some were legitimate but others made for folks looking for a quick settlement from a company. a new bill coming out seeks to limit the number of frivolous lawsuits. others are concerned that the new bill would endanger small businesses or individual inventories who have patents or about to file them. one of those concerned with the new bill, congressman dana rohrabacher, who joins us now. congressman, great to see you. thanks for coming in. you don't deny a lot of these lawsuits are frivolous, do you? >> i deny the word a lot. there are, large numbers of suits that are filed because megacorporations, multinational corporations, are more and more going to the tactic of trying to steal from the independent inventor rather than respect the rights that they have because they own the patent on their inventions. yeah, there are some scam artist
