Silicon Valley's high-tech firms are fighting what they consider a deeply personal federal cut this summer that shelves a planned patent office in this innovation-fueled region.

While most of the country is feeling some pinch from the automatic budget cuts known as sequestration, tech leaders say this one is unique and unfair, because the Commerce Department's promised satellite patent offices were never going to be funded by taxpayers. Instead, they're supported by the $2.8 billion in annual patent fees collected from inventors, entrepreneurs and companies.
