The cost of a successful lobbying presence is measured in the tens of millions of dollars a year, which is chump change for an industry as big and influential as the tech industry. Heck, construction companies have a much more organized and effective lobby, and they basically make no money at all (see the article on the front page about their 1% margins). Really, it's not that much money. Raise it on Kickstarter or whatever.
There is a bizarre mental block/persecution complex/"I'm going to take my balls and go home" phenomenon at play in the tech industry that's makes no sense to me. Silicon Valley isn't a special snowflake and Congress isn't going to divine its needs and tend to them. You've got one side telling Congress that absolutely everything needs to be patentable to keep the Chinese from stealing all our technology, and nothing but deafening silence in response. What exactly do you expect to happen in that circumstance?
