IP is a slippery slope indeed but personal use is allowed in all cases. Ironic seeing how the whole point of establishing the patent system was to encourage open ideas and sharing of innovation while protecting the inventor for long enough to recoup R&D and some profits. Now days I have seen electronics patents that have been granted for 40-60 years!

Now what about providing free plans for others to use? The Russian who made the Portable Slot Mortiser would be hankering for a lawsuit if in the USA but then I discovered Stumpy Nubs version and I wonder if they have had any legal pushback.
