Patent Search Tools
Some good patent search tools when doing patent research or looking for help with the research.
The US Patent and Trademark Office (www.uspto.gov/) has an excellent pubic interface. And while not the definitive search for all patents, it is for the US and the US firms still generate about half of the world’s patents.
Google now includes EP (European Patent documents) that one had to search for separately. Google also has a prior art tool that can be accessed from within any patent document searched on Google/Patents (www.google.com/?tbm=pts) . As cool as this is it does not search other prior art database Google does not have access to.
These are direct links to search for patents in Europe, these are searched (worldwide.espacenet.com/) by Google, and see what is registered, (register.epo.org/espacenet/regviewer) but it also makes sense to trust be verify.
Is the fee service for searching patents offered by LexisNexis and is a fine, if expensive search tool. internationalsales.lexisnexis.com/our-solutions/corporate/research/totalpatent.aspx
