Patent databases and Patent websites that include millions of Peer-reviewed articles
The following government websites provide patent databases for searching.
Canadian Intellectual Property Office Patents Database : www.cipo.ic.gc.ca
US Patent and Trademark Office: www.uspto.gov
European Patent Office: www.epo.org
In addition, there are two websites that have features not included in the government websites, and often with patents from elsewhere in the world, not listed in the government websites.
These two websites also have several million articles, mostly peer-reviewed, that provide a comprehensive resource for research in science, technology, and medicine.
