I'd guess so. Every lawsuit that a patent survives makes it stronger for the next, no? IANAL, but as a developer I loathe every S/W patent that does not have source attached and therefore does not properly describe the patented thing.

Having all three layers of protection means that corporations can reap the benefits of patents (legal monopoly) without "paying" the price (public disclosure of innovation).</soapbox>
