 All right, so I'm going to do a quick video that shows how to search for a patent on the website of the US Patent Trademark Office and how to download a PDF of that patent should you choose. So if I hover over the patents link here and then go down and find the link that says search for patents, I'm going to click on that. On this page it gives me several other links. This first one is to the database for full patents and that is useful in most cases. The next one is for the database for patent applications, which could be useful if you are looking for something that's relatively new. For this, I'm just going to stick to regular issued patents. On here it gives me a bunch of other links. I think this first one will work for our purposes, which is searching for full patents, full-text patents since 1976 and I'm just doing it. I'm just going to do a quick search and I'll pick something to search. Perhaps robot made would be something I'd be looking for and that search brings up two results. The second one looks closer to what maybe I am looking for and if I click on that link it brings me to the full text of the patent and I can see that this one is actually a patent for the Roomba, so it's issued or assigned to iRobot and I could scroll this page and it will show me the text of the patent and a bunch of other things not formatted very nicely, but all there. If I want to view say a PDF of this and view some of the images and things like that, I'm going to go ahead and click on images and this brings me to a page that will bring up a PDF document. So this first document that's showing me is just the front page of the PDF or of the patent and it's useful often times just as a summary. It doesn't include all the information, but gives me the high-level overview. I could click on some of these other links on the left-hand side to view other things, so get into the figures and page through those using the navigation and such. But suppose I just want that summary, so I'll go back to the front page. Here I can go ahead and click download and it'll download a PDF of that front page. I can save it. Great. Now I have a copy of that for my records.
