Finding nothing is the easy part. Deciding whether what you found actually blocks your claims — and drafting around it — is the work. Our registered Patent Agents do that, and it starts with ten questions.
Protect Your InventionCoverage. Two indexes: Google Patents, with full text for the US, EPO, WIPO, China, Japan, Germany and the UK; and the European Patent Office's DOCDB collection through its Open Patent Services, covering over 100 patent offices.
Indian applications are included — with English titles and abstracts — which is a real change from the Google index this page used to run on. What is searched for India is the title, abstract and bibliographic record, not the full specification. For the Indian legal position — status, oppositions, renewals — the official source remains InPASS, and we can run that search for you.
An absent result means “not in this index”, never “the field is clear”. A professional novelty or freedom-to-operate opinion looks at non-patent literature, foreign-language equivalents and claim scope — none of which a keyword search sees.
