Extract patent numbers from case law, filings, etc.

[mlissner]

This is a request I've gotten a number of times over the years, but I've never really looked into how feasible it is. I suppose a regex would get you close, but I imagine it would have a lot of false positives (maybe AI could help eliminate these?).

Lots of IP lawyers around here. Maybe somebody has thought about this.

Once we've got the numbers extracted:

• Let people follow them
• Put them in an API
• Make them searchable

What else?
