In many cases.
1. Hardware patents can be enforced against software.
2. Hardware patents can be enforced against the critical infrastructure
for an Open Source program. For example, I run GNU Radio, a
software-defined-radio program. I have a Universal Software Radio
Peripheral (USRP), which is a hardware device essential to making GNU
Radio work for any bandwidth wider than what a sound card will handle. I
want to protect the USRP against patents too, or GNU Radio is pretty
3. We should be able to protect the OpenCores VLSI designs and other
Open Source hardware designs. They are also potential hardware
infrastructure for Open Source software. Someday the available
off-the-shelf PC hardware may be bound to Trusted Computing features
that do not admit Open Source software. Thus, it's in our interest to
preserve our own path for VLSI creation.
4. As you can infer from #2 and #3, the line between hardware and
software is blurring. Thus, we are getting many purported hardware
patents that are actually software patents.
