Find That Patent
The U.S. Patent & Trademark Office says:
"You can search patents on the web, but you can't do a patent search."
In order to apply for a patent, one needs to know whether anything like it has already been patented. In order to determine this, one needs to conduct a "patent search" to discover if a similar product has ever been patented.
While we recommend getting a patent search with a qualified patent attorney, we also suggest that you do a preliminary patent search yourself because you will learn a lot about your product by doing this preliminary research. By doing a preliminary search yourself, you will also be able to compare the results to see whether you came up with any patents that were not on the patent attorney's list.
FindThatPatent.com provides full-text search ability for your preliminary research. All the patent bibliogrphical data, titles, abstracts and claims are fully searchable. The database contain all the patents issued after 2 Jan 2001.
