Which credit fits your investment project best
Using the patents that are most similar to your invention, click on the link for each patent that is listed under “References Cited.” This is the prior art that has been listed as being the most similar to that patent. This is where you will find the patents that are similar, regardless of when they were issued. Often you will find patents dating back many years in this section. Examine each of those carefully, looking at the images if you need to, in order to understand how they are similar or dissimilar to your idea. If you continue to pursue your invention and a patent application is filed, some of these same patents may be cited as prior art on your application. Look at the classification numbers on these patents to make sure that you have not missed one that should be checked.
