I'm not a lawyer either, never was, and never plan to be. The above is 
probably an appropriate explanation of the license as intended by the 

But I'm wondering whether such a licence would actually hold tight when 
considering patent exhaustion (first sale). Under patent exhaustion, it 
seems impossible to e.g. sell patented bottle openers but restrict their 
use to home use, in exclusion to commercial use (e.g. in a restaurant or 
bar). What is it that would allow such distinctions for cameras but not 
for bottle openers and the like? Or is it just that nobody yet has 
brought a case before a court?

Just wondering aloud.
