I think you could come up with some sort of patent truce, you use a search engine that finds overlapping patents. The truce comes with a constitution/trust that declares some metrics for that search engine. Any patents that go over that metric are not to be used for litigation by members of the truce. You can require members of the trust to invest in the trust at level relative to market cap. Breaking the trust results in loss of the assets/cash invested. The trust can also fund a defense pool/lobbying budget to protect the interests of the trust. Namely that members outside of the trust cannot successfully litigate on patents the trust hase agreed are frivolous. edit: obviously transparency, open membership and some high profile members are useful for such a plan.
