Patents

I started as a mathematician (PhD from Warwick Mathematics Institute in 1972), when mathematicians did not write patents:  but writing Claims turns out curiously akin to the core mathematical activity of devising a good scheme of Axioms, to capture the shared character of a significant kind of Thing. (Axioms are not 'self-evident truths':  the axiom X Y  =  Y X holds in many algebraic systems, but in English Killer Rat  ≠ Rat Killer ;  the axiom defines "commutative", so we can test which systems obey it.) A good set of Claims captures the 'spirit of the invention', just as a set of Axioms captures what it is to be a ring, or a field, or something else worth being. As Ian Stewart says somewhere, "The future does not lie in the theory of generalised left pseudo-heaps":  tweaking Axioms or Claims without a target is profitless.
My first patent took some months to write, and was filed when I was 50.  Now I am 65+, they come a bit easier:  the most recent (with the deadline of a need to go public at a conference) was drafted in about a week.  Our actual inventing did take longer…

In medicine an artery is patent (open) to the extent that it is not clogged: the dates below show that something else is clogged.  A pity, because the system of exchanging a temporary monopoly for making an idea open instead of a trade secret once boosted technological progress.  Nobody seems to remember that it started as a way of easing useful knowledge into the public domain:  the private monopoly, not the public patency, is the idol in the temple of Intellectual Property.
If an idea could really be property (people who worry about others 'stealing their ideas' usually have rather few), it would be property without a time limit, like freehold.  A patent is a loan of exclusivity from the real owner — society — in the hope of development and deployment as interest.
I do my best to pay it.

Where development can attract resources without that temporary-monopoly trick,
I would rather go copyleft and open source.
