As a surgeon there's nothing more devastating than being in an operating room and having to replace a piece of tissue or an organ and not having one to replace it with or not having the ideal treatment and you know you're not doing the right thing by doing that, by the see your only choice. And so for us to actually place these tissues in organs and to create them outside in the laboratory and to have them available would be a really good option for some patients and that's when inspired our work. You know innovation has always been present in this field dating back to the early days of just the concept of getting it done but it's really interesting you know innovation occurs when the science has actually gotten to a certain point where the breakthroughs can occur. You know and so what we have done is basically any time we saw barrier we had to find major ways to get around it you know and it's not till you get to that barrier when you start thinking about how to get around the barrier. So the first step to innovation is really just to try because if you don't try you'll never find a solution. One of the most important things that I think is related to innovation is to just not accept the accepted truths of the field because what happens is those accepted truths were true when the science was not yet that advanced. So you have to keep re-examining the questions that you look at given the new tools that you have at your disposal. I think it's extremely important for innovators to be able to protect their work. First of all there's the issue of putting a stake in the ground that this is the work you've done and to this work actually allows others to know what has happened and it allows them to go after new inventions and make new advances as well. The second thing is that if you are able to have the intellectual property at hand it allows others to really make an investment and if you don't have an investment the technology will never be transferred. So people will invest in the technology they know it's protected because they need to know that their investment is safe and sound. Literally takes hundreds of millions of dollars to really create these technologies so they could disseminate it to the public. People need to know that they're going to get a return to their investment for these technologies to be used and therefore if we really want to see these technologies used in patience you need to have intellectual protection. There's so many things out there that are really good technologies that because they didn't have adequate intellectual property no one ever invested in them and they never reached the public. So at the end of the day is not a question of whether we need intellectual property, it's a question is can we afford not to have it because it can impact patient's lives, the technologies depend on having intellectual property protection. We are focused on making sure that we create the best technologies that are going to be transformative for our patients and are going to improve the patient's lives and if that is true, if we are in fact able to create technologies which are transformational and that will make patients better, then healthcare providers by default will want to use that technology because it is transformational and the difference is much higher than another technology. It all starts and ends with having a technology that is transformational for our patients.
