We are reviewing the patent databases that we subscribe to and wondered if anyone else out there uses Thomson's Derwent Innovations Index and what their views are on this database?
Has anyone decided to cancel Derwent and rely on free patent databases over the web?
Can anyone recommend reliable patent databases that are available over the web?
I would be grateful for any advice and I will summarise responses for the list.
Many thanks
