I’m inclined to think this is a flawed study, as Lyn suggests; just a single snapshot of an entity with many facets.
Consider the following statement from the article:
They found that despite the purported incentives to American rosarians through patents, “European breeders continued to create most new roses, and there was no increase in the number of new varieties per year after 1931.â€
It does not take into account the fact that there have been (yes, past tense) at least two hugely successful companies in the US that enjoyed long and prosperous lives, and it is not a coincidence that these were the two that adhered strictly to the innovate-plus-patent paradigm. If this approach to creating proprietary varieties didn’t work, then you can be sure these companies would not have embraced it. The fact that both are now defunct has far more to do with the fickle nature of fashion in the industry, and the general decline in the horticulture industry than anything else. You can’t even begin to blame the patent issue on their demise.
Do more new cultivars really come out of Europe than anyplace else? I find that a suspicious statement and would like to see the raw data to support it. Perhaps Kordes alone tips the scales in Europe’s favor, who knows! All it would take is one or two entities aggressively developing new material to make it appear as though their region was far more successful at the process, but to conclude that the patent system is a pivotal factor is supposition and nothing more. Two or three data points per continent is not enough data to draw conclusions that suggest who is more successful than who, and why. Of course, with both Weeks and J&P gone, there are no full-sized corporation type nurseries doing R&D in roses now! Of course Europe is far more prolific in creating new cultivars, because they still have nurseries doing it!
While I generally feel that patents are unhealthy for many of the industries that employ them (software especially), it is a different scenario entirely when living materials are concerned. Neither you nor I can make endless copies of the latest Intel CPU chip nor clone a word processor from its source code and sell copies to all our friends, but we can make unlimited copies of any given rose, and there is very little to stop us from doing so. But the patent system at least suppresses such activity, and I believe that it discourages commercial nurseries from propagating patented plants without obtaining a license and paying the royalties. That is not an unreasonable application for the patent concept, as it provides at least a partially successful avenue for the developer to generate revenue from their creation.
That said, it is no secret that patents suppress innovation. I’m not even going to start to make the case for it; its a well-documented phenomenon.
Regarding ‘Bridal Pink’: I’ve said this many times in the past: if a rose persists in commerce for more than twenty years (or ten even!), then it must be a good rose in some regions. If it was crap in every garden it was attempted in, it would have vanished long ago. I wouldn’t dare suggest that because many Austin roses are disastrously disease-prone in my garden, that they are going to be failures in every garden, every region; that would not be true.
