Neil,
Although I respect the spirit of that restriction; I'm curious as to why 'patent' is included in the list 
… By their very nature, patents are public disclosures.

Pedant Alert!
Also trademarks. This thread names Dormer and Presto. Even more shocking, the rest of the forum is littered with mentions of the e-commerce site that may not be named, the Tight that is Lock, Yourford, Microsnot, Mug Alloys and many other examples.
I'd mention 'Rules are for the obedience of fools and the guidance of wise men' except it's ©Douglas Bader.

Simple enough, if it's legal to use/share the material and you are not infringing anyone's intellectual property rights you have the necessary permissions.
It's not unknown for forum members to share things they don't have the rights to and when this is realised or pointed out to us we take the material down.
The best way (and what i try to do) is link to third party material if there's any question – like those loctite manuals, link and let people download from Henkel, we don't have permission to host a pdf copy on this site.
