Signal Relief Patch costs about twice as much as Actipatch, but is much less effective at reducing pain and will probably never gain FDA approval. However, they do have money for marketing and advertising - I see their ads on TV every day, along with on-line media. They could be a good partner for Actipatch - we could use their advertising/marketing budget, and they could use Actipatch (integrated with their patch) to make their devce more effective at reducing pain.
