Your assumption is right.  No scope is the same as no patent; it won't help to defend PostgreSQL community against
rivalcompanies/communities of other DBMSs.  Or, I think we can set the scope to what OIN states.  Fortunately, anyone
canjoin OIN free of charge.

Are you assuming that developers want to use PG code snippets for non-PostgreSQL or even non-DBMS software?  I believe
thataccepting patented code from companies would be practically more useful for PostgreSQL enhancement and growth.
PostgreSQLis now a mature software, and it can be more corporate-friendly like other software under Apache License.
