Law & governmentfree
Free worldwide patent search from the European Patent Office. Patent PDFs upload well for prior-art review and technology landscape notebooks.
Espacenet gives free access to the actual claims and citations in a patent, not just a marketing description of the technology, which is what a notebook doing prior-art or technology-scan research needs. Patent language is dense and legal, and searchability differs by country and filing date, so treat a null result with some caution.
