Sites like HalfBakery and this shared Google Doc act as open repositories for potentially patentable inventions. In effect, these sites act as anti-patent databases because the inventions are never pursued, but are available as prior art in the public domain. Is there currently a site or service that aggregates all of these different open repositories into one location?


Defensivepublications.org has done some work in this direction, but there is no centralized database that I'm aware of.


Don't know of a centralized database. Yet another resource is IP.com. They have have a defensive publication service. You have to pay to publish there, but you'll have the benefit of a more trustworthy documentation system.


Research Disclosure have been offering this kind of defensive publication service for a long time.

Research Disclosure is included in the PCT minimum documentation list, the major patent authorities are required to search the archive when examining patent applications.

It's a paid service but if you're looking to create an effective block against future patents it's a good solution.

  • Note that I believe Defensivepublications.org publishes their materials into the RD database, so there may be a two-birds, one-stone solution there.
