Utility patents and Plant Variety Protection (PVP) are independent mechanisms for protecting plant germplasm. PVP has a research exemption (i.e. PVP protected varieties can be used in breeding without restrictions) and a farmer exemption (i.e. farmer/grower saved seed for personal use is allowed without restrictions). There are dozens of current tomato lines protected by PVP. Utility patents restrict all commercial use of the patented material - no breeding, no saved seed, etc. Although the parents for most commercial corn hybrids and most soybean cultivars are patented, this has been rare in tomatoes.

Interesting thread. The never-ripening tomatoes probably were meant to never ripen on their own, so they could grow to full size in the field, be harvested all at once, and then be ripened by being gassed with ethylene in a warehouse. This trait might be useful to home gardeners who could store them over the winter and ripen them as needed by putting them in a sealed container with an ethylene source such as apples. But I think there are naturally-occurring genes that do pretty much the same thing without patent issues.
