It is now possible to get access to US patents online through Google. These are sometimes rather erratically captioned but once you get the hang of the categories as defined by patent-lawyers its relatively easy to work out a way to what you’re seeking.
Does anyone know if other countries patent services are also online and if they are, how one can access them?
Patented designs aren’t only the well thought out and commercial, they also hold details of the seriously wacky and the strange beyond reason. In other words, a goldmine of delights for anyone interested in the inventiveness of the human mind.
Happy collecting, Peter
