Hi, Kathy! I know you’ve been working on your patent and researching it for what, two or three years now, and, as you find out, it’s not as easy or straight forward as you’d like it to be, so you’ve been coming to the library to do a lot of your research. And could you tell me more bit about it or how it’s helped you by being here?
You see KATHY STARK responding to his question.
Yeah, this is really kind of a one stop shop, I mean it’s gonna…it’s gonna to accomplish a lot by coming here. Um, first you’re going to be able to see um prior art by looking at trade journals, and academic journals, and magazines and newspapers. I mean you helped me figure that out, and that was really helpful, but then I think the average, you know the person who has this burning idea for an invention, I think they’ve got a couple of things that are, that’s top of mind. One, um, is my idea unique, is it novel, and um so you need to search patents and patent applications, but then also you may want to pay um ah an intellectual property attorney to do a search and you’re going to be able to minimize that cost if you have better information.

Database search engine for patents in the state of Minnesota and it’s, for me it was, and it is just much more, it’ s just more robust in the display function. So I had four hundred and eighty patents to look through. Um, you advised me to write to the patent office and because you spent two years there with your fellowship, I mean you really knew what you were talking about and you gave really great advice on what to do. So that letter that I wrote to the USPTO came back and it gave me class and a subclass to search under for patents. So, I mean this site really, um, it’s just, it’s just a really well-kept secret because anyone who has this burning idea, this should be your first stop because you’re going to be able to get great information and you’re going to save money.
