Although there are many comprehensive databases available, the most thorough search you can conduct is through a patent attorney (feel free to skip to the last paragraph!). Most of the free websites are very similar to each other, which makes it difficult to pick one as the best. Here are some for you to check out:
- – probably the best because it’s from the source itself. You can search by keywords, classification, inventor, assigned entity, attorney, etc.
- – probably my second choice because the advance search provides a ton of filters.
