You could maybe tax them at an appraised value, such that the patent right has to be licensed at at most x% of that value. If they under value then it's cheaper to license it, if they overvalue they pay more tax?

Or maybe a first-sale doctrine that allows a single sale but doesn't allow further sales. You better be sure you want it because once you bought it the resale value is zero? Then troll companies wouldn't be able to sweep up lots of older patents to use in trolling.

Or, it could be like trade marks, of you're not using the patent in a product then you lose it, unless you're the original inventor. If I sell you the patent, then you keep it to troll with you have to make a product that uses it, and sell that product, otherwise the patent expires. It doesn't return to the inventor - they got paid - it enters the public domain.

These ideas are entirely my own and presented for entertainment only.

Nitpick: that’s the exact opposite of the “first sale doctrine”. The first sale doctrine says that, once I buy something, I can do whatever I want with the product. If I want to shoot bullets at a $1000 smartphone for YouTube views, Apple, Samsung, etc. can’t prevent me from doing so.

There are exceptions to this (EULAs and all that), but the general idea is that.

Yes, that was confusing: 'The' first-sale doctrine is about exhaustion of the rights of an IPR holder though (as you correctly state); a consumer can resell because the creator of the IPR no longer has power over the goods.

My off-the-cuff proposal would be 'a' first-sale doctrine that would exhaust the rights of an IPR creator by preventing them from being transferred. To a [further] third party. This mirrors 'the' first-sale doctrine.

Of course 'a' first-sale doctrine is just a protocol related to a first transference - in the case you reference that's transference of goods to a consumer, in my proposal the transference was of IPR rights to a manufacturer/troll/company.
