Not really. Ownership of land, chattels, etc. are usually considered natural rights--- the government protects your ability to own things, it does not grant you that ability.
Copyright, trademark, patents, etc., are different; they were not considered natural rights, but are a social engineering effort, attempting to produce specific effects in society ("the progress of science and the useful arts", e.g.) by means of government-subsidized policy.
As an analogy, consider another government-granted monopoly, say taxi medallions. They're quite valuable in some markets. But they're entirely an artificial right, created by the city for the city's own reasons, not an inherent one.
Or on the opposite side, consider e.g. liberty or free speech. In the American or liberal conception, those are innate, inalienable rights. We create a government that hopefully helps us exercise those rights, but the rights inhere directly in us--- they are not granted by the government or some other third party.
"natural rights" are of course nonsensical without resort to the supernatural. The founders are Christians and diests, for the most part, so natural law fits within that framework. It has no relevence in a post-religion world.
